Has anyone rebuilt one of these? The one in my 92 lumina has no more 4th gear. I'm looking to try rebuilding myself. Does anyone have a how to? Also was told I should add a shift kit to firm up the shifts when I do the rebuild

http://www.transgo.com/products.php?cat=4T60E&homeinclude=catalog&category_id=105&parent_id=105 Shift kit and accumulator parts. I've come to appreciate Transgo shift kits vs. B&M or other "famous names". There's a bunch of different wiring changes on the 4T60E, at the big round connector. For example, I can't swap a 92 Euro 3.4 trans into a '93 Euro 3.4 car. I have a Kent-Moore "special tool" that can shift the transmission into all the different gears, but there's a bunch of different wiring adapters depending on what application the trans is configured for. I don't have many of the wiring adapters.

I picked up a parts car 4 door 93 euro this morning and plan on pulling it apart and swapping its goods to mine. Picked it up super cheap since the body was a little rough but not bad. Maybe I'll have a running and driving car soon

There's nothing like a clean engine, this thing has been covered in grease from where it's never been cleaned although that may be a good thing knowing it hasn't really been boogered with by previous owners/shops. I think I'm going to do the plenum and valve covers red and polish the aluminum fins . I think it would go good with the white. Something similar to the stock fiero 2.8 look

Been making good progress got the engine and trans separated and the transmission out on a dolly. Plan on pulling the upper intake maybe tomorrow and see how the gaskets look. If all goes well maybe I'll paint the plenum and valve covers to dress them up a tad

A 92 with a 3.1 (LHO) engine you'll have the 440T4(4T60) trans which was the predecessor to the 4T60E, if you're going to attempt to do this yourself see these links. the *master* kit doesn't include the *hard* material, http://www.transmissionpartsusa.com/440T4_4T60_transmission_master_kit_p/370-000037003.htm you'll need the additional items to replace the damaged internals http://www.transmissionpartsusa.com/440T4_4T60_transmission_solenoids_s/6401.htm http://www.transmissionpartsusa.com/440T4_4T60_Transmission_thrust_washers_bearings_s/6387.htm http://www.transmissionpartsusa.com/440T4_4T60E_Vacuum_Modulator_s/6397.htm http://www.transmissionpartsusa.com/440T4_transmission_parts_s/6392.htm http://www.transmissionpartsusa.com/440T4_transmission_bands_s/6386.htm http://www.transmissionpartsusa.com/440T4_transmission_filter_s/6385.htm http://www.transmissionpartsusa.com/Transmission_Repair_Manuals_s/6395.htm obviously you've got to have a manual to guide you..........there will be need to remove & replace any worn bearing (some of them will be needle bearings), assembling the clutch piston, a guide for selecting the proper thrust washers for the input shaft end play, Try to get an proper manual for the trans, the more exploded views you see will help the process. good luck with this

The 2 revisions are with or without the 2nd gear switch 1994 4L60-E is very different. With the discovery inside the radiator in mind perhaps swap the entire 1994 powertrain?

Sounds good, I've been looking at rock auto and they sell rebuild kits for the 4t60 reasonably

two versions in 1992 looks like the second gear switch.

Someone had asked for my old write-up on the TCC apply issue, with no overdrive when hot. http://www.w-body.com/topic/41994-95-dohc-cutlass-p0740-no-overdrive-no-tcc-when-hot/

What is the parts car you have? I can look in alldata and see if that tranny is the same for you.

Unfortunately 4th gear doesn't work at all, I found this in the trans pan. I got the cradle dropped enough to where I can access the transmission stuff and get it out hopefully

If your 4th gear is working when cold, then goes away when the transmission is warm, you probably have an issue with the TCC apply piston...pretty common on the 4T60. The piston is known for galling the cylinder it rides in, and then it sticks in the bore. With the torque converter clutch unable to lock the converter, the ECM disables overdrive to try to save the transmission from high temperatures. I had this problem with my '95 Cutlass convertible, and it actually took a second rebuild by the transmission shop to resolve it, because they didn't listen the first time when I told them what the problem was. A scantool that can read torque converter slip percentage data from the ECM can confirm what's happening. Mine would work perfectly, until transmission temps exceeded 180 degrees, then it would disable 4th. Shutting down, and restarting the car once it was warm would allow 4th to work for a minute or so, then the ECM would disable overdrive again. You might find that simply replacing the valve body resolves the problem. There's a fairly long description of the problem that I wrote on this forum about 8 years ago that more fully describes the problem.
