So I found a 1994 4l80e transmission for 600.00 that came available because the 6.5l diesel suburban it was in caught fire. The harness and speed sensors were melted but the trans fluid was clean and the owner claimed it had only 18000 km on it. After some time I had a transmission shop install it into my 1993 2500 4×4 with a 454 engine .
The truck is not showing any error codes, but it does not shift unless you let the gas off . I don't believe it goes into 4th at all and the kick down seems almost hyper sensitive.
I should also mention that we used the electrical from the 93 trans that was in there, but did not change the solenoids or torque converter. From reading here I think I understand some of the differences between the years, but was really hoping some one could offer some work around to make this 94 work I the 93 truck.
