Hello folks, Well the kid decided to take her truck 4 wheelin' and mud boggin' and now I'm trying to fix the truck. The truck is an 1996 C/K 1500 regular cab, short bed, 4.3 vortec V6 with a VIN of 1GCEK11W5TZ140050
, manual 4x4. The truck was running fine, no service engine or check engine lights until she was done with it. Now the rig has the “service engine soon” light on and doesn’t upshift or downshift like it should. I took it to Autozone to have the codes read. Well, lets start with:
, 1-2 shift solenoid electrical circuit
, 2-3 shift solenoid electrical circuit
, Torque converter clutch, Pulse Width Modulation, solenoid electrical circuit
, Torque converter Clutch Electrical circuit
Shift Timing Solenoid circuit
Obviously I wasn’t a happy camper when I was done at Autozone. Tried finding a manual to repair the truck, with no luck. Every manual I could find is your basic tune-up stuff. Any one know where I can find a wiring diagram so I can try and fix this thing since everything seems to be electrically related. I’ve given it the general once over looking for broken wires, vacuum lines which I’ve found this truck doesn’t have.
BTW, it is also is throwing a P0152
codes which I’ll deal with at a later time.
