    4L60E Information Thread (Includes 4L65/70/75)

    Yep - that's the Gen1-compatible two-piece case 4L60E - note the lack of a 12 oclock bolt hole, compared to the LS/Gen3 SBC 4L60/65/70s, example shown below...Compare the input shaft on yours to the one in the pics below.

    4L60E Information Thread (Includes 4L65/70/75)

    Do you have a picture of the front of that two-piece 4L60E by chance? My guess is that it was a Gen1 SBC two-piece case, those were produced for pass cars and trucks between 1998-E2000, had the Gen1 SBC bell housing bolt pattern (no engine-bell bolt hole location at the 12'oclock position)...

    Undertightened cork gasket on TH350 and whole thing flooded, clean and reuse?

    DO NOT USE CORK! A standard composite gasket is fine. Bolt toruque is 13 ft lbs. No RTV, either. If you have to use it, something's wrong.

    1984 k10 700r4 won't shift out of 2nd please help!

    4L80E all the way; the 6Ls cost nearly twice as much to build for any given application, especially when power levels exceed more than 50% beyond stock...

    '76 with stock 12 bolt question

    You'd need to tell us how much power the engine will be making (ballpark) and how you plan to use the vehicle. If power goes way up, Id go to a 14 bolt FF.... What transmission will you be going with?

    Performance 700r4 rebuild

    That sucks, man - sorry to see...i had a similar situation a month ago - found out the stator support was warped. Had to cannibalize another 700R4 core to put that pump back together.

    TH400 Information Thread

    Then a quality build with a rollerized output thrust, Sonnax LB1-TH400 kit, feed orifices enlarged a tad per your preferences along with the usual stuff (clutch module, new seals, sealing rings, o-rings, etc plus detent solenoid) should be sufficient...I'd have him install 4L80E center support...

    TH400 Information Thread

    Install Alto high energy frictions, Sonnax TH400-LB1 boost valve kit, dual feed the direct clutch, drill the spacer plate per application, shift firmness preferences and converter stall. If pushing more than 500 hp, id also install a billet rollerized forward clutch hub. Rollerize the rear of...

    Performance 700r4 rebuild

    Those rarely leak...try tapping it with a drift to reseat the check ball to see if it stops leaking...If not, replacement is easy as I'm sure you know.

    Performance 700r4 rebuild

    @Wumbo - For some reason this website isn't letting me quote but the round hole rev input drums are obsolete so yea, was def a cost cutting measure...Not the end of the world, just odd to see in one of their transmissions...Also odd to see Z-pack as it's the one Raybestos product that is...

    700R4 Information Thread

    I think there's a diagram for the transmission's internal wiring harness in the 4L60 ATSG manual - I'll pull it down and take a photo to post in reply a little later today.

    TH400 Information Thread

    You're welcome - the below video should address all of your questions and then some - it's of my TH475 build up but otherwise is identical to how I'd build yours, other than maybe dual feeding the direct clutch (I didn't do that in the video) but it's very easy. Hot tank the case and all...

    TH400 Information Thread

    @DoubleDingo - Yank and overhaul the unit...Sounds like all of your applied elements are worn but will be important on tear down to determine if the wear is simply normal for the mileage and usage pattern or if there are other causes like hard part wear/damage...Inspect the lip seals, their...
