I just purchased 95 K1500 and, along with someone doing away with the emissions on the engine, I noticed when taking off the transmission starts in 2nd gear. ODB1 and No codes. I tested the A solenoid while driving (someone else was driving while I put a ground on the light green wire) and the transmission will shift into 1st gear. I'm thinking the computer being bad. Before I purchase another, does anyone have other suggestions?
