i just did a tranny swap a mtx in a mtx 4 door, but i was told that the comp wil swap out. the 95 wont work in the 98, does any one know how to make it work?

 

easiest way is to get one from a mid 96 97 98 or 99 and swap that out

 

What does a manual tranny swap have to do with the computer?

The '95 PCM was unique to that year. The '96 PCM was unique to that year. The '97-'99 PCM are interchangeable. The only difference between the '96 and the '97-'99 is one pin, for the rad fans. The '95 is 100% completely different to deter swapping, since it is not 100% OBD-2 compliant (still OBD-2, but skirts some of the laws that '96-up had to follow).

The few people that I've known that have tried cutting and splicing the harnesses to fit have always had problems. Better to swap over the entire harness and just cut and splice the handful of sensors that are different.
