If you could choose any manual transmission to throw behind your 12 valve which one would you pick? Comment Below!

I have a 91 (unmodified) with a Getrag and shifts smooth as silk. As much as I know these are work-horses, I drive it right and don't lug it. Treat it with respect and your bank account will love you for it. Great info.

Excellent information on the manual transmissions. 👏 It's amazing how many hours can be spent with Google and reading on forums trying to find clear answers. Tim thanks for a much simpler answer.

I had a 07.5 with the g56 and really liked it. Idling in neutral It rattled like a bag of marbles til you mashed the clutch pedals. I only had the truck 3 years but I hauled some heavy loads with it and the truck never even hiccuped. A 3 axle trailer with 14 round bales was the biggest load I ever towed and it never even lost any RPM’s in. Those control at 65mph. The wife was really impressed when she rode along on that trip. She never really understood why I insisted on a stick shift or a Cummins but she said “now I understand why you wanted this kind of truck”.

Great information. After doing a lot of research myself and scouring online forums for hours over the course of the last year or so, this is probably the best single place to find the information that you've gone over comparing these transmissions. Super informative and well put together. You're gonna save LOADS of time for people in the future. Thanks for all your other videos, too. They've helped me a lot on picking things to do for my 85 crew cab build

G56 AE is what I would want for my 1st gen. Thanks for the video helped me learn a lot more about these! Can’t wait for the next video too!!!

This video is gold!! The information is spot on and super helpful. When they built my g56 they used some early g56 parts instead of keeping the late g56 parts in it and it was night and day.

You got me on edge - can’t wait for the video man!! I have a G56 in my 3rd gen with 250,000 on it and can’t kill that thing, was also thinking about putt on in 1st gen and this video will be awesome - keep up the good content I always look forward to you videos. 🙏🏻

Excellent video!!!!!!! One important thing to remember is higher gearing does not always mean better fuel milage. Engines can be over geared and get worse fuel milage. The most important thing to remember is correct engine RPM at a certain MPH range. HP and torque need to be taken into consideration when choosing gearing. Ultimately you want a low enough first and reverse with the correct final drive gear ratio, with enough ratios in between to accomplish the task the truck is expected to perform. Diesels like 6 or more gears for moving heavy weight because of their narrow power range. If a vehicle is slightly under geared there will be no noticeable increase in fuel usage. If slightly over geared the engine can struggle and cause increased fuel consumption. Also, the speed of the drive shaft in relationship to the engine crankshaft does not automatically decrease or increase fuel milage ("over drive") but is just a term that is used to describe the crankshaft turning slower than the drive shaft as power is transmitted through the transmission. Weight of the vehicle, wind resistance, engine HP and torque, rear end gear ratio and tire diameter all need to be taken into consideration when choosing the final engine RPM. A transmission does not have to be "over driven" to have all the correct gear ratios that are needed for a specific application. This is why there are different rear end gear ratios and or tire diameters available.

Thank you!! I cant wait for the series

So ready for these vidyas. Awsome job Mr Tim

Great video again and looking forward to your upcoming trans swap videos (planning to swap a manual in my 1st gen as well)

Excellent video. Simple and right to the point and the diagrams kept my attention. Very good. Thank you.

Excellent video, good recommendations! I've always been curious about these things

Fantastic information and very well presented!

Awesome, really enjoying the channel, learning a lot, keep up the good work

Great video and information sir!!! Very good stuff, can't wait to watch your conversion!!

Fantastic information. Grate job keep up the good work. Look forward to seeing more

My first gen is needing a transplant soon, so definitely following this one.

I have a getrag and G56. G56 for the win. Thanks for the content

The G56 AE model for the win😎🤘🏻 That’s by far my favorite manual transmission. I do own two trucks with NV4500’s and I’ve always like them as well. Great video Tim!

Great video, I can't help but think that the benefit of the cast steel case over aluminium is actually more about the gear shafts not "walking" and creating excessive backlash and adversely binding the engagement area of the gears. Aluminum is stiff, but cast steel would be better at maintaining the overall structural integrity needed in such a high torque area.

so excited to see this!!!

Great video! I have a 93 w250 which is highly modified. Running a p7100 pump from farell diesel. Borg Warner 362sxe with massive Haley speed injectors. Still running stock rebuilt Getrag, she feels stout. Of course it’s overfilled 1 qt to help with cooling as much as possible (running royal purple full syn gear oil. I would estimate truck turned down right now is about 500whp. No issues at all, running a southbend dual disk clutch. Thanks for the info!

I'm 4 days post-swap. 07 5.9 48RE to G56. Pulled the 48RE with my Dad one weekend. Put the G56 in the following weekend with 2 Cummins enthusiasts. Huge thanks for the work and the format of your videos. Helped build confidence to do this. You also helped me ensure that I got the AE model witch fit my driving/pulling/fuel economy needs. Couldn't be happier!

I had a 2001 Dodge turbo diesel 4x4 6 speed manual and really liked it. I sold it and now want to get a 1992 or 1993 turbo diesel 12 valve inner cooler, regular cab, long box, 4x4, manual and want to keep it stock. I haven't driven one since I was 16 so don't remember how they drive. I hope that I'll be happy with it and not want to change a thing but we shall see. Great video!

EXCELLENT VIDEO! There is so much confusion/ inaccurate information out there about this topic and others surrounding dodge diesels. I didn't see the g56 swap coming, hopefully it works great for you. I have a suggestion for a future video. You did a great job explaining the manual tranny options for a cummins, why not do the same for the automatics that dodge offered, and explain all the misinterpreted things from the diesel forums( which transmission was offered when, which trannys had overdrive, which ones had lockup torque converters.) Just my $.02.

I had the nv4500 in my 1990 I really enjoyed it.

Excellent info. I needed this

I have a G56 in my 07.5. I’d love to have one in my 1st gen. Can’t wait to see the install

Excellent video. Very informative. Enjoyed it. Thank you.

Nice break down Tim. Both The Dodge Whisperer and Half Way House Garage have done the G56 in their 91.5 W350 and 93 D350 Dodges. Great swap and worth the investment. Feel free to hit up either one of those guys if you have any Questions. I think Halfway House Garage has short over view video on his. My current plan is a Eaton Fuller 6406 and if I can't find the one I need then I will go G56. Great Video Tim!

A lot of info and very detailed. Thank you

Great Information. I actually have an 84' crew cab that im currently working on for a friend and it has the G56 trans. The only issue is fitment. It rubs against the tunnel and vibrates the floor. Hoping your series of videos will address this concern.

Cant wait to see the videos on the g56 swap. I definitely intend on doing a g56 swap on my 4th gen when my automatic goes out

My Dad and uncle both had 2011 crew cab duallys with the g56 and both put upwards of 275k miles on them with no problems whatsoever. Personally I’ve driven all dodge manuals and can’t say I prefer one over the other. It just depends on your set up and what you do with the truck daily. Looking forward to seeing more videos your content is great!

Very good video Tim 😉👍🏻

Great info Tim. You make me want to put a six speed in my crew more and more 👍👍👍

Your video just popped up on my feed. Great video. I've been lucky enough to drive all 4 tranny's. However, my daily driver for the last 21 years is a an '01 2500 with the HO motor. 5600 behind it. I wouldn't trade it for anything. I've gotten so used to it, I don't even use the clutch. It floats as smooth as silk. Upshifting, and downshifting. And the icing on the cake....being able to drive it this way, I just changed out the factory clutch. At a half million miles. I'll be a 5600 guy forever!

Tanks great video I have 2004 5.9 24 valves cumins 6 speed I loved my truck

awesome video, great info!!

The NV4500 was also offered in some 2003 trucks. It came with the S.O. Engine option. Great video.

good to know i have the best of the best in my 01 3500 nv5600. i love the trans its smooth as butter

I got lucky with mine. 2000 non53 block 2500 HD with NV5600 6speed. It did have the smaller trans shaft. But when the synchros started to go out in 5th and 6th, I had it rebuilt to the beefier spec. It's my forever truck, lol. 😎👌

Great content! I have A 01 with a nv5600. I bought it with 140k it already had a slight bent input shaft some kid owned it and I'm sure he was doing burn outs with it. It now has 260k At 215k the main seal started to leak so I just did a budget fix and put a new seal in it. Lasted 30k miles and started to leak again. Now it just has a very light leak. Every 6000 miles I add 1 qt. So far most I have towed combined weight is about 28000. I just hauled a d2 5j dozer 8 hours out of town. Once it starts leaking more I think I'm just going to overhaul the nv5600 as I have blown up at least 3 nv4500s. I tow heavy all the time my truck never sees daily driving.

The nv4500 5th gear nut will not grenade the transmission if it backs off. If 2wd, pull the driveshaft and tail housing and simply screw the nut back on. YOU MUST USE GL4 TRANS FLUID! It’s like $300 for a full rebuild kit and very easy. You must buy a bearing puller and heavy duty lock ring pliers along with a new main shaft.

Great info, I’m a huge manual dodge guy and have multiple of each manuals besides the getrag. You hit all the points I could think of. Nv4500s are great for lower hp or stockish pickups, the only competition use where an nv4500 fits very well is sled pulling. Guys run tons of power through them by only using direct drive and installing 4.56-4.88 gears. For anyone putting together a street truck though the nv5600 is arguably the best choice. I’ve got one In my 03 that has around 750hp and it’s been awesome. All factory 300k mile trans. Worst part about an nv5600 imo is just how complex of transmission it is and how it’s harder to rebuild than any other dodge manual. Cody alberect has really been backing the capabilities of a g56, supposedly the early models with the lower ratio od are stronger and he can swap later .74 models to the .79 ratio. Between that and his new input shaft he’s released a g56 may be a great option for a hot rod stick shift truck

Awesome video!

I had a 1993 1st gen with the Getrag. I bought it with 29k miles and the Getrag had the “sound of imminent death” . I bought the extended warranty because I didn’t expect it to last more than a couple of months. The tranny finally died at 179k miles. It was only at stock power for the first month I owned it. Torque at the rear wheels was just north of 1k lb/ft for a couple of years before it died. Believe it or not, I ran Rotella 5w40 synthetic in the tranny (engine too). I filled it through the shifter so that the oil level was greater than just filling it through the fill plug on the side.

Great content. Been wanting a 6 speed for my '97 for years. Thanks.

I've owned a 1992 with a Getrag, 1997 Nv4500, 2002 with a NV5600 and now a 2006 with the G56 AD model. None of these trucks are modified. Just plain tow rigs, farm truck, cattle haulers and hotshot work The early manuals were always decent in their day. I could always criticize the 5 speeds for huge gaps in gears when pulling heavy trailers (10k - 20,000 lbs) The G56 is awesome and matched well with the 2006 cummins. Excellent truck as long as you don't need to ever go faster than 75mph My 2007 Megacab with an automatic is smoother and nicer. But I always have concerns with any auto. I'm looking forward for a G56 AE sometime

I’ve fixed several nv 4500 5 th gear nuts for several people never seen one explode myself you just lose 5th gear they keep driving them till they can get them fixed when I ordered my 02 I ordered it with the nv 4600 trans, shift on the fly no vac disconnect on front axle, high output engine so that it came with the Dana 80 rear axle I new about the issues and and that is why I ordered it with these options that I did I’m still driving it today 👍it’s been pulling backhoes excavators dump trailers camp trailers still going and still looks good !

mmmmm good to know about this , i own 92 d350 with 5sped n i can tell synchro's going out n i had 06 g56 truck n love the g56 but like u said gearing is to low at 65 i had 2200 rpms , drove 2016 g56 and it was much better . keep up the good work cant wait to see this 6sped in ur cool truck !

Super informative. Thanks.

Awesome video man. I also really liked your series where you installed the g56 in your truck. Did you notice a significant difference in power/fuel economy when going form your automatic to the g56? I have a 1993 W250 with a 47rh. Thinking about swhiching to the NV5600, but not sure it will be worth the expense. I'd love some feedback form any of your guys who have done the swap.

Great content! Gained another subscriber

That button up is fire

Both our work 2nd gens have NV5600's, and I've got zero complaints with them.

I switched from the G360 to NV4500 with finned cooler (one with a filter) on each side for my 93 (rwd). It required modifications to crossmembers, shortening the driveshaft and sheet metal work. The 1993 Service Manual included a section for the NV4500. The NV4500 weighs a lot more than the G360. Using the GL4 synth oil in the NV4500 has been expensive. The NV4500 has been rebuilt once since installed as a new unit.

Great video. Thank you.

Great info 👍 Thanks!

I have a 2017 with a g56, reverse is to high especially when backing up in tight spots such as campgrounds. To avoid smoking the clutch I put a 2 low switch in and it works very well…….

I’ve gotten 06 3500 all I do is use it for pulling but you get on the freeway sixth gear at about 65 mile an hour you’re about to red line, it’s screaming. I hate getting on the freeway with it, but it’ll pull anything

Nv5600. Bulletproof in my 04 with a southbend single infront of it. 4.10s, 4 door dually with an aluminum flatbed. I’ve hauled 20k behind it up here in Alaska multiple times and it doesn’t skip a beat. 40’ gooseneck tandem axle dually with a Gehl skid steer and materials.

I really like my 12 Ram 2500 with the G56 in it. It's getting a new throwout bearing and pressure plate right now, the rest of the South Bend Dual Disc clutch is fine and I hope to put another 230K miles on her!

Great video 👍

I went with a ZF6 from a 6.0 powerstroke and a WildHorse Mfg adapter

That's good info thank u!

I have a 2001 2500 with a nv5600 and I absolutely love it ive drove plenty of g56 trucks also and me personally I prefer the nv5600

Nv4500 was available in limited quantities up until around 2005. It was behind the common rail in the 3rd gen.

Pretty excited for that video. I have an nv 4500 in my truck, I'd like to put a 6 speed in it. Either one would be fine. I'm only around 400hp.

Hi amigo i live in Reno i like yours videos .yesterday i buy a truck here in reno it is 2002 ram 3500 with 130 Thousand miles for me is unique truck the owner pass way. I buy the truck to his wife but these truck it is on amazing condition db power turbo exhaust brake very very nice truck I can not believe the condition Happy to cheer pic with you.

Great video

After watching this I made some notes driving my 98 turbo whistle. 3 to 4 shift isn't that big of a jump. It's less than 2-3 and it's certainly less than the 1st-2nd. Shifting up at 2000 RPM 2nd = 1000 to 1020rpm 3rd = 1075 4th = 1150rpm 5th = 1475rpm I have noticed that fifth gear is only half a gear before but recording this definitely hammers that fact home. I would love if my overdrive was .73:1 or .72:1 like the baby 13 🤗 RTLOO-913 Ideal pickup transmission. Aluminium housing yessir 👍

My mid year 2003 has the NV4500. 5th gear fell off at around 275k. Barely ever lugged it. It's just one of those inevitable things & it won't grenade the trans, you just won't have overdrive. Drove it like that for 2 weeks. 5th is all the way in the back of the trans, technically not even in the main case and is easily fixable by removing the rear tail housing. 5th gear will just be hanging out on the back of the shaft. For reference, mine is a 4x4 model. Slid it back on, added the nut fix & it's now pushing 294k.

Good info.

Very informative.👍

I am not completely convinced that lugging them has any effect on the synchros. Synchros are only used when shifting from one gear to the next

Great input on transmissions for dodge

id love to have an nv5600 with a gear vendors behind it, 12 speed and deep overdrive is a dream

Can’t wait for the complete episodes of the g56 install I daily my first gen was a automatic put a nv4500 I like the nv4500 compared to the getgrag I have one in my other 1st gen Seeing the video I want to get the g56 as well Also if I can find. A good deal a nv5600 and a zf6 to see how they run 💨

Yea I don't know why more people aren't putting G56 in their first gens. Maybe the thinking of all the fab/wiring work scares them away. Personally I would swap one in my 06 to get rid of the 48RE before my first gen. Can't wait to see how yours performs!

G56 all day every day. I've driven them all and it is by far the best.

Great looking truck buddy. I just got a used NV 5600 6 speed tonight. I bought it for $1,000 it seems to be in great condition and was said to have driven to the parking spot where it was taken out. Thank you for the input it's nice to know that with the inch and 3/8 input shaft I have one of the best transmissions there is to put in my 2001 3500

I have had the nv 4500 and 5600. I like the 4500 better for daily driving and light loads , it shifts better and with 5 speeds you shift less. For heavy towing the 5600 is nicer . Ive got gear vendors overdrive s behind them both and if you have deep gears 4.10s or deeper the overdrive is really nice when empty. The guys do shift faster for sure.

Great video I personally have an nv4500 in my first gen and I have had to deal with the 5th gear nut I don’t wanna step on anyone’s toes but when you lose the nut you do lose 5th but the transmission isn’t destroyed you can easily fix this with the transmission in the truck I like these transmission because of how easy I can find them in Utah

My G360 has 518k miles on it never been rebuilt. Just keep it overfilled with 5w30 Royal purple and it loves life no matter what

They did also change where reverse was on the 2 different g56 trans. The first Gen reverse was beside 1st gear and the 2nd Gen was beside 2. Small clarification that is not really noteworthy but figured I’d tell you 🤙🏼

i bought my dodge in 1990 an currently have over 400,000 miles on the G360 trans. it's been good. the only thing i did was modify the vent for it. Just ran a hose up the firewall. cause the check ball was leaking.

I just found a clean looking second gen 12 valve 1994 2500 with a g56 already swapped into it. Going to pick it up Friday for $8000. I am excited 😎

Make sure to replace clutch components if you get any sort of vibration through it seen the g56 cracking bell housings before from bad clutches

If I wasn't doing a Eaton with overdrive I would be putting a brownie box behind a factory Getrag. A well taken care of properly driven G360 is hard to beat.

I've heard the complaints about the aluminum casing on the g56. As if every other transmission used in modern trucks isn't aluminum as well. I wouldn't call it a weakness as i've never seen one break simply because it was aluminum vs steel.

I have a 92 f350 dually with a 91.5 Cummins running the zf5. South bend clutch I put new synchros and bearings and new reverse gear. Got 4.10 rears, it was a gasser. feels like when the light turns green I have to get to 3200 rpm’s in third gear to pass pedestrians on the sidewalk.

Can’t wait.....

Gracias thanks 👍 NV5600 is the best

Love your channel just got your info through fab rats! I’m a Cummins nut at well

NV5600 with a big input is the best close to factory trans behind a 12v IMO. Throw in a dual disc clutch and they're beafy as hell, safe to 500whp/ 1000ftlbs all day. The G56 shifts better but not as robust. I think the best 6 speed manual trans you can put behind a 12v is actually a zf6, need some aftermarket parts to make it work but they shift as well as a g56 but are as strong as an nv5600.

I ordered a 2005.5 model when it first became available. When the dealer later contacted me they the dreaded Good News/Bad scenario. The truck had arrived but Dodge had initiated a system wide hold on deliveries due to reports of the G56 having catastrophic failures within days of driving off the lot. I was so disappointed but decided to wait for the cause of the failures to be determined before cancelling the order. Luckily, the problem was due to the factory lubricant fill being inadequate. Once they topped up the fluid I went and picked up the truck. Unfortunately withing a couple of months the synchro's for L failed and had to be repaired under warranty. Perhaps it was partially my fault although based on the fact there is now 350,000 miles on the vehicle with NO other transmission issues and the first clutch lasted 250,000, I would have to believe I'm fairly easy on my equipment. One thing that's been an ongoing annoyance ever since the warranty trans rebuild is difficulty shifting into 2nd gear when at a dead stop. Its like the shift collar gets jammed and cannot engage all the way.

Delo 5W-40 Synthetic oil solved our problems with the Getrag.
