Thank you very much for the info and sharing it definitely helped with a few questions i had. I did however have one question, you may have said but figured I'd ask just to check. I have a 05' 4l60e and a 06' 4l60e. I'm upgrading/rebuilding the 06' after a 3/4 burnup. After teardown i was not comfortable with the splines on the stator shaft of the 06' and figured id swap it with the 05'. After research ive seen the differences you talk about on the input shafts. I have the weird one your missing in your video. Now my question is and if you know, can i use the 05' pump, stator, input shaft assembly/housing in the 06' transmission in place of what was in it. Both input shaft housings are 716, but the input shafts are different hence why I'll use the corresponding pump with it. That being said the 05' pump has the old style sealing ring around it and the 06' uses the metal clad stepped type. So if i use the 05' pump in the 06' transmission case should i leave the original ring on and use the new metal one also since the case is designed for it or am i swapping cases also. Sorry if that's alot lol and greatly appreciate any info.

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...

Another great video. I'm wondering what you would consider minimum clearance in the 3-4 clutch pack on a performance build. I currently have a 097 input drum using a Sonnax 74140-01K HD 3-4 backing plate kit using a #7 stamped apply ring with the Borg Warner 3-4 maxpack kit with high energy frictions and kolene steels. I have 8 frictions installed with approximately .042 clearance, is that a little tight or is it ok? Thanks for any advise, very much appreciate these videos!

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.

Ok great info Just one question So i bought a used 4l60e transmission from a 2006 vehicle 4x4 my vehicle is a 2007 chevy suburban 4x4, i was checking the insides and noticed that the pump doesn't have the speed sensor like mine, and the imput drum shaft also doesn't look like mine with those groves for the speed sensor, can i still rebuild it like this or i have to get a different pump and input drum shaft? Also is the cases exactly the same or only the inside parts change? I will really appreciate your help

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).

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 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

Well, I finally bought a 700r4/4l60 transmission, from a 1992 Oldsmobile Wagon. The transmission + converter + cover with bolts + tube, cost me the equivalent of US$ 450 shipped.

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?

@nickstransmissions

6 ай бұрын

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.

Did not I understand you saying that I could put a 30 spline earlier shift into a 4L60E drum?

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

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...

Hi Nick, I am Denis From Chile.Please, help me with your recommendation for my project: I am starting with the rebuild/upgrade of my 1986 700r4 (86 Firebird 305 TPI stock engine for street/city use). My goal is to feel the automatic gear changes of this car as similar as possible to a modern car. According to my researchs, I have 3 options for this: 1.- Rebuilt my 86 trans with the necessary case modifications + valve body swap w/aux. + 87-93 rebuild kit + opening the pump hole and grinding a bit the case, for pipe installation. 2.- Buy a 1991 Blazer used transmission and rebuild it (local market is reduced for parts and import parts values are increased by freight costs + tax). 3.- Buy a 1993-2013 used 4L60E, remove and use all its internal parts + modified 86 case + valve body w/aux system + rebuild kit according for trans year purchased I don´t know yet what happens with output shafts and converter compatibility.

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: kzread.info/dash/bejne/oHtsuLuBe7azppM.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!
