Hello. My 1994 Eldorado ETC (4.6 Northstar) was showing a CEL and throwing P094, P095 and P076 codes. I replaced the A and B solenoids, reset the codes and test drove. The P094 and P095 codes are gone and have stayed gone. However, the CEL came back on almost immediately and the P076 code is still there. The car will not shift into third or fourth. It shifts only from first to second. HOWEVER, if I clear the PCM codes and leave the diagnostic function engaged, the car shifts fine. When I take it out of diagnostic mode (pressing defrost) the car immediately goes back into second. I have the pressure solenoid and will put it in, but I got to thinking that there may be an electrical issue I am missing since I can apparently override the "malfunctioning" pressure solenoid by leaving the diagnostic mode engaged. Anyone have any clues? Many thanks in advance!
