This gearbox was used on RWD 4WD cargo vehicles and off-road vehicles with the engine from 3 up to 6 liters. This 4-speed transmission for RWD cars was constructively based on the popular HydraMatic 700R4, but produced at the GM factory in Toledo (Ohio) and proved to be very efficient.

They're where I get all of my stuff from and have great prices.The 4-speed family of GM transmissions named as TH700R4 (Turbo-Hydramatic) 4L60E/ 4L65E has been launched in production in 1982 and after some minor changes was renamed as 4L60. I would suggestion looking up Oregon Performance Transmission for rebuild parts.

(aka sun shell) The OEM one is a known failure point, and the aftermarket has solved that with various upgrade pieces. The only thing really worth upgrading internally for a stock or near stock engine is the reactive shell. With a rebuild kit that includes all new clutches (duh), thrust washers and especially seals, you'll have a good piece on hand. Since you have two transmissions on hand, I'd use the planetaries, sun gear and reactive shell from the 2000 in the rebuild of your original transmission as those are upgraded parts from GM. Like I said, you're going to be rebuilding it anyway. The valve body from your 94 will not interchange with the case of the 2000 because on 96-up transmissions, the TCC apply valve is in the valve body, and in 1993-1995 transmissions it's in the pump housing itself. To answer your questions in reverse, you can't do that. If you were to grenade a set of planetaries for example, a GenIII transmission is a great source for OEM upgraded parts on the cheap.

*edit The only reason I went that route to begin with is I was able to pick up complete late model units with upgraded hard parts and miscellaneous stuff I needed for like $75, plus I'd have spare stuff for rebuilding transmissions of later years on hand. It's confusing and you just wind up with a frankenstein. For a couple of years recently I kept two on rotation because I broke so many parts, so I've been down the route of picking up used transmissions on Craigslist from various years and swapping parts until I stopped beating on it so much. You're honestly better off though ordering a complete rebuild kit and rebuilding the one you already have in my opinion. Output shaft, planetaries, reactive shell, sun gear, etc all can be used on older models. (to simplify it, all the round guts will swap just fine, including the torque converter) Want more confusion? You COULD use everything out of the 2000 transmission you bought EXCEPT the case, pump, valve body, torque converter, input shaft and input drum. Everything except the valve body and pump will interchange, if that makes sense. Namely, keeping the case, pump and valve body (including electronics) from your original 1994 transmission, and swapping over ONLY the hard internal parts. If you were versed in rebuilding these things, you could use anything up to 1998 with a little fuckery. The only two years that will DIRECTLY interchange would be 1993/1994. No other year will interchange DIRECTLY (more on that later) due to the design of the valve body and PWM TCC valve.ġ999-up will not interchange with anything previous as the GenIII engines used a transmission with different length input shaft, among other things. 4L60Es had so many variations in trucks.ġ993/1994 transmissions are interchangeable.ġ995 is a one off year.

This could get long, but basically you're SOL.
