ok i am still having problems with the trans in this thing...heres what i have...its a 94 z28 with a 95 pcm trans in it..the d6 to pin u installed into harness and the pcm reprogrammed with the 95 tune for the trans..still will throw the 3-2 downshift feedback fault..butt with a 95 pcm installed it dont throw that code and it dont go into limp mode but it does have check engine light on and fans come on but the scan tool isnt reading any codes..with the reprogrammed 94 pcm it will only throw the 3-2 downshift code also with the 95 pcm and maybee with the 94 pcm it engages real slow into reverse..fluid id up and it didnt do that when pulled from other car...at wits end with this car and i am about to go with a 700r4 maybee
