1999 GMC Jimmy 6 cyl Four Wheel Drive Automatic
i have recently rewired a 99 gmc jimmy at the power dist. Block and at the pcm. I used the mitchall manner diagrams. I have cheked all the wires three times and i'm still having problems with the torqueconverter locking up as soon as it shifts out of 1st gear going into 2nd. The speed sensor calls for 5volts and I am only getting 0.64volts. I have replaced the pcm and still have the same problem.I have scanned it for troble codes but come up with nothing. The "check engine" light gos off like it is supossed to. The engine runs fine. Where does this problem sound like it may start
have the same problem?
