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

    Hey Everyone, Starting a similar thread to the one available for the 700R4 but dedicated to the 4L60E as countless GM cars, trucks and SUVs were fitted w/them from 1993-2013/14 and often retro-swapped into Squarebodies. Posted below is my teardown and inspection video that covers everything you...

    TH400 Information Thread

    They look/sound familiar, perhaps they're on eBay or sell via Amazon...If they provide kits w/Alto, BW, Raybestos, etc friction elements they should be good to go...Most of my soft parts are either sourced locally via Transsttar's distributor here in town or distributors out of Cali. Transstar...

    TH400 Information Thread

    Since you're outside CONUS, best bet is probably eBay or perhaps Amazon. I like the kits sold by Transparts Warehouse (ebay search: "TH400 Deluxe kit); most come with upgraded Alto high energy clutches, new steels, both bands, paper/rubber kit, bushings, filter, etc. For a stock build, you...

    TH400 Information Thread

    You're welcome, Ken...Symptoms can be an indicator of worn applied elements, particularly the forward and direct clutch packs...There are two applied elements working when in reverse: The low reverse band and direct clutch. If the direct clutch is stressed, it won't grab until there's sufficient...

    Remove the housing retention bracket then speedo housing/driven gear from the case. Then count the teeth on the driven gear if there's enough of the teeth left to count. You should also be able to view the drive gear and count the drive gear teeth by rotating the driveshaft...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    No one does a cut and clean, if its going to a converter builder, it will be completely rebuilt, which is exactly what you should do. Never reuse old converters with a rebuilt transmission. I always provide a new one with my rebuilds...

    You can use the TCI gear calculator to get a good idea of what you need, drive and driven gear wise when it comes to tooth count. It will get you close but the only fool-proof way is to simply count the teeth on both gears...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    The trouble spot is the 1-2 check ball location...much more so than the others however if Torlon check balls were used, it's not likely to be worn as if steel 1/4" balls have been installed. If you have to drop the valve body and plate again for any reason, please post a picture of it cleaned off...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    You're welcome, man and appreciate the views and sub! Gotcha, yea for now, keep the 7 check balls...One question - do you have a picture of the spacer plate all cleaned off? I'm curious to see what, if any, mods they did to it...From what I recall from the last one I did, they drill the plate...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    Anytime there is failure in the gear train, thurst-driven destruction is almost guaranteed as once individual components start breaking up, teeth start stripping, you being to have significant, uncontrolled (and violent) longitudinal travel of the rotating assembly, either in part or as a whole...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    POS shell! But it didnt fail...Have to look elsewhere...Rear gear train failure mimicks/replicates the symptoms of sun shell failure, the loss of rev, 2nd and 4th... Man, what a mess.

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    Technically, you dont adjust rear end play in the 700R4s or 4L60Es as everything is free to thrust against the pump. But excessive front end play can also indirectly cause this sort of failure...Excessive play results in the forward drum thrust bearing being hammered by the stator as the parts...

    4L65E Mega Monster Transmission - Destruction and Shift Kit check balls

    Monster Transmission, LOL!!! All the monster transmissions I have torn down (mostly 4L60Es and a few 4L80Es) all looked basically stock inside, including stock frictions, basic shift kits or mods and nothing overly innovative; same is true for their OTC 'Monster in the Box' kits...You can buy...

    700R4 Hard/Delayed 1-2 shift

    You can simply remove the governor from the transmission and do your mods to it with the kit on the bench; no need to remove the trans. The governor can be accessed at the rear of the transmission. Simply remove the governor cover retainer clip, if one is installed then take a smooth, flat blade...

    I’m interested in swapping out the TH350 for a 700R4

    What is a "4700"? No 700R4 came from the factory without a converter clutch however you can convert to a non-locking converter using transgo's Non-lock up conversion kit.

    700R4 Hard/Delayed 1-2 shift

    You likely have a standard governor causing shift points to be later when a diesel governor would be more appropriate for the diesel given their torque curve vs a 350 gas engine's. You can pick up a Superior Tech governor kit to modify it so it shifts a bit earlier so it doesnt wind up the...

    Turbo350 w/shift kit slamming 2nd gear

    Fun Fact: Chrysler was nearly bankrupt for large portions of the 80s and early 90s and didn't get around to developing overdrive transmissions until nearly a decade after GM and Ford. When they did, they leveraged their A345 design from the mid-70s, which was a an optional extension assembly...

    Turbo350 w/shift kit slamming 2nd gear

    Yep, avoid 82-E84 700R4s or convert them to L84-87 standard (30-spline shaft, newer design "152" drum and 29 element sprag. Top it all off with a factory 10-vane rotor/slide kit and it's good to go for most applications.

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

    Glad you were able to get it fixed! That said, it wont be the problem here as the 700R4 doesnt use a vacuum modulator. The modulator system for managing line pressure and p/t shifting was replaced with the throttle valve system for the same purposes in the 700R4.

    HT350 and Overdrive Question

    No towing in OD if you can avoid it...trans coolers are always recommended, esp in heavy duty applications like towing/hauling. There's a few other things Id do to the transmission specifically for towing, let me know if you need a quick list of them. Main thing you need to know with the...

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

    Agreed - ive rebuild several Monsters and they leave a lot to be desired...I also provide a brand new detent cable with all my 700R4s and 200-4R builds to eliminate the stretched/worn cable scenario as it is common for them to not hold or simply snap. Even when the customer burns up the 3-4...
