Im having this exact problem! I have been chasing the code p0758 shift solenoid B fault. Ive dropped the pan three times now on my l460e. Ive suspected various parts but non the less. Tried them all. What started as a fluid and filter, at 238k started a nightmare from hell. I'll be doing this first thing tmrw! Scottie!! Keep up the great advice and content! You may have saved my a$$ and pocket💪😎🔥🔥

So I just recently ran into this problem with my sons LS swap camaro, everything he explains in this video we have done and still no first gear. It turns out it was wrong or bad o2 sensors. I guess the trans grounds thru them. Put new ones in and works like a dream. Just wanted to share our experience with everyone

I bought a 4L80E off of ebay rebuilt. Same problem! Already changed the 2-3 B solenoid will have to try your fix.

Thanks man. You are genius. I think I have the same problem because my b solenoid valve won't come out. Thanks again.

Yup agreed.... This is the first video (after watching probably 20+) that talks about cleaning the valve area. This was my line of thinking from the beginning especially since I added transmission cleaner and then instantly the transmission didn't function properly... how would a solenoid fail immediately after putting that stuff in....

I just bought a 97 Z28 and thought the shift solenoid was bad but it ended up finding out that the guys that had the car before me put a new transmission in and did plug it in to the pcm😂

Thanks a lot man! Just got done doing what you did here to m 96 trans am ws6 and it worked like a freaking charm! Thanks for the info!

Lmao I just lost first gear gettin out of work😂watching for help thank you

Thanks for the info. I'm not worried about this not being a Marvel's studio production

I had that problem a while back and drove it like that for a while before I changed them out but mine just started acting up it acts like it's in neutral if you try to take off in OD or 3rd but it will take off in 1st or 2nd and when I'm up to speed I can switch to 3rd and then OD and its fine but it won't down shift if I apply enough throttle for a downshift I just had my valve body out because both solenoids seemed fine with a multimeter and hooking up 12v but I had one that I was pretty sure was good and replaced one of them and I thought I switched them so if I was putting in the bad one the symptoms would be different it was the same but now I am getting a code for shift solenoid b so I ordered 2 new ones and am going to double check the wiring too

I’m having this problem I replaced all the solenoids in my blazer but still moves slow in D but 2 works somewhat better at slow speed.

KINDA LATE TO THE COMMENTS, BUT I LOST FIRST (IT WOULD ENGAGED, MOVED A FEW FEET AND ENGINE JUST REV LIKE IN NEUTRAL), I FOUND METAL SHAVING IN OIL. I GUESS MY PROBLEM IS MORE LIKE MECHANICAL THAN ELECTRIC. DID YOU HAVE METAL SHAVING AS WELL ?

Mine is slipping 2nd gear, im pissed because we fought that damn pan out and changed the Solenoids but i didn't check or clean the valves

I have a 1994 Camaro with that transmission, the selenoids are fine but I have the same problem of not having the first gear only 2 and 3 gear, the board does not mark me check engine Do you think the valve could be dirty?

Which one is solenoid A and which one is Solenoid B. Is there any difference in solenoid A and B? Do I purchase 2 of the same catalog number for A and B to be replaced? I have a 2015 5.3 Yukon with a transmission 4L60-E-RWD. Will you tell me what the catalog numbers are using AC Delco parts for these 2 solenoids. Thanks Chris

thanks

hi i have a 2006 Mitsubishi eclipse an I flushed the converter an the pan an put back factory fluid in it an went to drive it 5 miles well it kills on me in reverse an it kills in drive , it killed on me while I was driving an it took a while to start back up . it only throws me po741 an its a automatic . The new fluid color even changed within driving 5 miles to a real light brown . Any help with my issue or issues is greatly appreciated

really thank u

every p0756 that you have solved. has been by dirty shift selenoid or dirty valves inside the valve body?

I have a 1995 k1500 4x4 truck and I have too manul shift it what dose that mean

I'm going to be doing my 94 k1500. I'm doing maintenance on the transmission to try figure out jerk shift out of park to drive or park to reverse. I'm switching the a & b solenoids, 1-2 actuator, filter and fluid. I actually should change the pressure plate. I was wondering about cleaning the valve bodies on the a and b. Did you work out the valves with a small pick or just use compressor air? Thank in advance. All my other gears shift great. Maybe I have a tow package upgrade in my transmission. Not even sure. I'll find out when I drop the pan a guess.

I have a 2003 GMC Denali awd my first gear is sluggish and second gear is gone third is fine and overdrive is gone. What do you think it could be.

i have a 01 chevy it feels like 2nd gear is gone. i have to let up off th gas for it to change then it rides fine. do you have any ideas on what it may be.

I have some code lexus gs300 2007 i went to garage and they said i neet to replace gearbox

Is that 2-3 valve supposed to be spring loaded? Mines not

buenas noches tengo una duda con una transmisión 4l60e de una Suburban 2008 repare el cuerpo de válvulas por fuerte golpe de 1-2 y funcionó solo que ahora solo golpea muy leve en aceleración baja y en aceleración alta no golpea nada no encuentro detalle en el cuerpo de válvulas y quisiera saber si hay un kit de correccion para 1-2 que me recomienden buena noche

Same tranny 03 Escalade. No codes, should I bother with solenoids? Already tried btsi fuse. Issue is, jerks kand won’t go to 2nd, can’t get out of first rpms red line. Do you do mobile mechanic work? Thanks for your solenoid video, so do you think I start with solenoids?

What scanner are u using to diagnose the transmission problems

So my 2005 chevy avalanche has started doing the slow to accelerate. I changed both a and b shift selenoid and it didn't fix it. My code reader thru out 3 codes and 5 pending codes. When you shift into drive it's feel like it drops to a different gear I'm thinking that it is going into limp mode. On the highway it runs at 100 km at 3000 rpms.

Thanks...

So that's it, I cleaned twice and replace solenoids and wiring harness plus swapped the valve body and still same problem any advice

Mine is doing the same thing

My transmission didn't have first and overdrive and it read solenoid A change it now I have all four gears

what kind of vehicle is this valve body for that you are working on...?

Do you think redline d4 atf is a good atf to use to replace the original dexron 3 and better than dex6 in a 2001 Silverado 4l60e? Going to change all my solenoids soon want to use a good synthetic atf do you think synthetic is best for these older 4l60es?

Whats up man i have a question

I have a Chevy 2500 HD 2007 I had selenoid changes all of them and transmission. reset but nothing. it takes off first shift but kinda get stuck on 2nd before it kinda pulls before taking off what can it be

Dude tell every one to go to top 5 auto repair on shift solenoid, rather then chasing there tails like you and trying to figure out (y) its still not the problem...

hello my is gear 2 it skip then just go 3 what can be the problem

Finest

Have the same code on my 2007 Escalade going to try it out

dont have nothing to do with not having first gear.

Could a Check Engine Light (CEL) code: P0756 Shift Solenoid B Performance or stuck off for a '04 Honda Accord EX 2.4L 4-Dr Sedan Automatic (approximately 259,000 miles) just be a Solenoid issue or something else (Pressure switch, etc) if the car is not going into Reverse for up to 2 minutes & the same thing for Drive (Have to wait a few seconds up to 2 minutes) Drive light blinks, Check Engine Light is on & that is the only code displayed; P0756 Shift Solenoid B performance or Stuck Off (Other issues: Sometimes there's a quick grinding sound when the car is switching into gear usually after the car is stopped at a stop sign/light then moving again, RPMs rev up high but the speedometer stays low & takes a while to switch gears. After the CEL had been cleared the car drove fine in all gears, 65mph no problem, etc then when the CEL & blinking Drive light came back on it had the issues listed above). Other Notes: Honda dealership recently drained/filled with new transmission fluid approximately 3 weeks later while up in the mountains I had a loose negative battery connection; dashboard lights flickered, RPMs reved high with harder shifting, after I realized it was a loose negative battery connection I used a SHIM to fill the gap>Battery connection issue fixed but then I started experiencing transmission issues; Just delayed shifting (High RPMs before kicking into gear) took the shim off which obviously involved disconnecting the negative battery cable then lone behold the car was shifting fine. Had to put the shim back in (loose connection) then the same transmission problems started to occur again & became progressively worse as mentioned above. Later after the car finally kicked into Drive it was taken to a transmission shop & they said they were barely able to get it into their bay by pushing it (While in Neutrel) They said it needed to be driveable to run their scan tool to pull codes/test the transmission & their final result is they said it needs a rebuilt transmission ($4500+) no code scans, test drive, they believe it couldn't just be the solenoid, etc. Since it delays so long and or doesn't go into Reverse gear or drive (Not sure how long they actually waited to give the car a chance to go into those gears). If the transmission is actually no good I will take it to a shop that takes the exsisting original transmission out & rebuilds that $2000-$2800 instead of this shop who only orders comptely rebuilt ones for $4500+ (They said they don't rebuild transmissions on foreign cars because they had too many issues & only rebuild original transmissions on American vehicles). Just wanted some feedback, opinions if they still could've scanned the vehicle properly since it starts & even if it can't kick into gear to test drive it and also based on this info if it still could be a Solenoid fix etc (Lengthy info in case this is helpful to determine the issue better & in case this is beneficial to anyone else experiencing similar issues).

Did you have lost of forth gear as well I have a 2000 gmc sierra 1500 4.3l v6 4l60e A/T and I do not have 1st or 4th

Your Transmission is failing & worn out, get new transmission

To do these, don't do it unless you're doing the video on.how you do it. Not just talk about it.

Boy you weren't lying about this being a shit video

get to the point bro

really thank u

i have a 01 chevy it feels like 2nd gear is gone. i have to let up off th gas for it to change then it rides fine. do you have any ideas on what it may be.
