i have a 92 3000gt sl and a 94 3000gt base. the engine crapped out in my 92 and the trans did the same in my 94. i was thinking of swapping transmissions but im not sure of the wiring was the same. i ran into a small problem where everything fit but the plug was wrong on thr radiator fan and i had to cut and splice the 94 plug onto it.
anyways, is there anything i will need extra for the swap?

Should specify auto or manual, but you will need to swap axles.

Not going to happen without extensive work. The valve bodies are different, the solenoids are different, the axles are different. Lots of work. Why Mitsubishi was such a pain in the ass on their early 90's ATXs being so different is beyond me.

could you explain a bit on the extensive work needed?

enough of a PITA to make it worth your while to simply source a correct-year transmission.

Real information on the Mitsubishi ATX's is elusive. I tried putting together a thread before asking for info on direct swaps and the like and got little help. On my own I figured out that 91, 92, 93, and 94 all were completely different part numbers, but SOHC and DOHC were the same. And that 95-99 were the same part numbers, but DOHC and SOHC differed.

Mitsubishi pulled the same crap in the DSM's. I had a 93 1.8 Eclipse that the trans went out on. I had a used car warranty with it and they wanted to just replace the transmission. After they did their research they found out it was a 93 year only transmission. They searched the entire country and realized the only option was to rebuild my transmission.

My brother ended up with a 93 1.8 Talon. His transmission died. We lucked out and found 1 transmission, only to put it in and find it DOA so we converted it to MTX. For simplicity's sake, either get another 94 ATX to put in, or just MTX swap it and be done.
