You are very welcome

Thanks, bcframers!

Thanks again, Kevin!

Thanks, man! Appreciate the views as always.

Yeah this guy is the real deal. I have to replay certain parts a few times to let it sink in.

@@doctorwebinstein4101 Yup Yup

Hi Daniel, thank you for watching! Are you producing these drums mentioned above? If so, do you have a link to website to find out information and pricing on them?

@@nickstransmissions yes. We have. What is your email address? I will send to you photos. If you are interesting. I can send to you samples

Hi Daniel - please send me a direct message on Tahoeyukonforum.com and I'll reply with my email address. My user name there is NickTransmissions. Thank you in advance!

@@nickstransmissions I just did. Hope you received. Thanks

I just sent you a PM on the Tahoeyukonforum. Please respond there with a link to your 4L60E drum when you get a chance...Thanks, Daniel!

Thanks, Edward! Yes, you can retro the #7 back to any year 700r4, including the early 152 and 368 drums.

Hi Keith, thanks for watching. Yes you can use the 05 pump assembly and input drum in the 2006 case. Since there's no speed sensor in your scenario and your ECM wont be looking for one, it will work. Main thing is to avoid mixing incompatible pumps and input shafts...

Hey Kevin, .042 clearance should be fine...If you're going to be doing lots of RPMs behind a big power motor, I'd install Transgo's high rate return spring kit as well, assuming you haven't done so already.

Yes I do have the transgo high rate return spring kit installed. Thank you.

We did upgrade 4L60 input drum, the new design is 10mm bigger diameter 3-4 piston. Take care of 3/4 clutch pressure problems. And we foundry steel 3:59 , then machining to steel spline. It will no cracked

Hey man, thanks for watching. You're close - but you want a '152' forward drum instead (video explains the reasons) if you're working on a non-aux body 700R4...The 716 and 097 drums were designed for 700R/4L60s/4L60Es that had forward accumulator circuits. Correct on the pump and torque converter. You will want to use a late '84-'86 pump cover/stator that was designed for the 30-spline input shaft for non-aux valve body 700R4s.

I actually have 99 4L60E the input drum was damaged by the reverse drum. It has the pilot style and I wanted to upgrade to the 300mm. Can I?

You didn't specify that so figured you were working on an early 700R4 as no 4L60E ever received a '368' drum - they went out of production in 1984....And no to your second question as there's literally no point to doing so if you have a Gen1 small block (agin, specify what you have and working on). thanks

I like them for the 3-4 pack, especially in a 7+ clutch stack up. I can't recall whether anyone has the tubular-style Kolene steels for low reverse or reverse input. No clue on the notch vs no notch.

Thanks for watching, dragonfist! Do you have a 700R4 or 4L60E? What year is your transmission?

@@nickstransmissions I think is a 700r4 but not really sure. The case number is 7YPM. It was in a 84 trans am.

Well, it would be an early 700R4, the "7" indicates a 1987 model year unit with a first generation valve body that has two pressure / pulse switches installed... Does it have a 27 or 30 spline input shaft? If it's a 27 spline, dump it and the pump and move to a 30 spline '152' drum and 303/304 pump body and cover combination. That will mitigate any risk of premature input shaft failure, especially if you're going to be hot roddin...

@@nickstransmissions. When I count the input shaft I get a 30 spline. That’s the shaft that’s connected to the drum.

Ok, than you have a 1987 unit, which is good because you don't want the very early 27-spline style 700R4 in there...Someone must have (wisely) swapped the original transmission at some point in the past.

Because they LEAK!!! Use 4L60E tan viton/rubber seals instead.

You can install any 700r4 or 4l60e input shaft into any era drum though all 4L60Es that went into V8 or 4.3L v6 applications as well as those that went into the inline five cylinder engines in the 2000s all received 30 spline input shafts. I would not recommend doing this with an 82-84 700r4 drum as you would want to use a “152” Drum instead as it has the updated 3/4 clitch pack bleeder oriface design

Ok, just thought I’d ask. Thanks for your reply. Thanks for your Great Videos

You’re welcome, Al and thank you for watching.

Yep, no issues with doing that. You can install them in 700R4 drums also...Some builders actually prefer the separate configuration vs the conjoined for high performance/high rpm applications but for stock/mild builds doesnt matter which configuration you use.

@@nickstransmissions Thanks a lot man, Im rebuilding my first transmission, it had something weird going on I dont know if I can explain you my situation to see if you can throw me some light

Well you can try and ill see if i can help steer you in the right direction. First - buy the ATSG manual for the transmission, assuming you dont have it already. That one manual usually helps 99% of the time. If you already have it and it's not helping then reply w/the question here, using all the correct terms for each part so both of us are on the same page about what parts of the trans you're describing or referring to.

@@nickstransmissions I had this 1994 4L60e stock on my Pontiac Firebird it was working good no slipping but one day at a red light when it turned green the car felt soooo heavy, felt weird cant really describe if it was starting on 3rd or 2 gears trying to go at the same time. and even on neutral if I revved it up it moved a little forward. starting the car it lurched a little forward. I bought another Transmission at a Junkyard put my valve body on it and the car ran good and sold it that way, that happened 3 years ago. But now I have another 94 Camaro and I need that Transmission so im rebuilding it, thing is it has no burnt clutches and everything looks good except the forward sprag on the 3-4 Drum looks way overheated and one of the faces of the sprag itselft its like welded to it, Im going to replace it but I dont know if that was the problem, or maybe there was something stuck on that drum that and I didnt noticed, The Manual I have says that the input shaft has to have a little play before dissasembly but this transmission didnt have any so thats why I think that maybe something was stuck, I tried on another transmission and could feel the play, if you want pictures or more info let me know. any input would be greatly appreciated, this is my first time inside a transmission

Hi Denis, replace the sun shell with a heat treated version, never reuse the factory shell in these transmissions. Ditto for the accumulator pistons -they are always replaced on overhaul. Buy the kit that corresponds to your year range, which is 87-93. Good luck with the build!

O.K., but what sun shell? there are a lot of "made in Taiwan" versions. In Asia, they put any word in its products: Treated, Special, Heavy Duty, OEM, USA, Germany, etc. Hard to believe everything they say. What do you use for the 4l60 rebuild?

Sonnax makes the best smart shell on the market so if this is your personal build, I'd make the investment and go with that one...TCI is also an option (very similar design)...Most of my 4L60E shells come from Transstar and I've been using them for over 10 years, haven't had one strip or fail yet. I imagine the shells come from Taiwan, which is fine. Taiwan =/= China, quality of Taiwanese produced goods is generally much better than anything equivalent coming out of China.

Hi Denis, thank you for watching. I'd buy the used Blazer transmission but if you can, inspect it before you purchase...You can check out my video on how to buy a used transmission here: kzfaq.info/get/bejne/pK1oibx5sLmxpmQ.html The 1991 will have an aux valve body and better 3-4 clutch pack compared to the 1986 forward drum so shift feel and timing will be a bit improved plus the 3-4 pack itself is a bit stronger though you can install a max pack or 4L65E pack to make it even better. The pump in the 1991 transmission will feature a 10-vane rotor and slide vs the 7 vane installed in your 86 transmission. Keep your existing trans in case you need gear parts and transfer your output shaft and extension housing from the 86 to the 1991 unit so you don't need to buy a new speedometer drive/driven gear kit and speedo housing. Also install the Sonnax throttle valve sleeve and plunger kit to proactively address any wear or leakage w/the factory sleeve and plunger...Insufficient line rise is usually due to the TV sleeve and plunger being worn. Hope this helps, let me know if you have any other ?s and good luck with the build!

Oh, thanks for take your time for a quick reply to me. My previous search was many days watching your "master class" videos @@nickstransmissions

You're welcome, Denis.

Hi Marcus, thank you for watching! You will need to acquire an input shaft w/the reluctor gear for the speed sensor and corresponding pump assembly (or swap your pump/input drum from the 2007 unit that you're replacing over to the 2006 unit if both are in serviceable condition) as the 2006 non-turbine SS pump/input shaft parts won't work. And replace the speed sensor itself w/a new AC Delco one as you won't be able to replace once it's been installed without taking the pump back out again. Everything else is the same, case-wise (inside and out).

@@nickstransmissions thank u so much for ur fast reply, the speed sensor always jave to replace when rebuild the pump?

Yes - always replace the forward speed sensor unless you don't mind taking the transmission back out again to replace the pre-existing one if it fails at any point after the rebuild.

Just took apart one with a 716 input drum with bonded pistons

Hi Gilberto, You will also need the updated return spring assembly, GM part 2426085 (reuse the one that came with it if in good shape). If you want to run a 4L60e 3-4 pack, you will need to install a #7 apply ring and 4L60e 3-4 backing and apply plates (delete all the 700r4 plates and apply plate support). What's the application (ie daily driving/cruising, street strip, off road, etc)?

@@nickstransmissions And the 716 input isn'tinterchangeable?

What year 700r4 are you trying to retro the 716 drum into?

@@nickstransmissions it came out of a 71 Chevy. Some one put in a 1991 700r4.
