This morning my service engine light came on. Went to the Chevy dealer
and found out two troubling things:
1. I'm out of warranty despite only 27,000 miles.
2. The 4 error codes indicate transmission problems.
740 Torque Converter Clutch Circuit Malfunction
758 Shift Solenoid B Electrical
785 Shift/Timing Solenoid Malfunction
1860 TCC PWM Solenoid Circuit Electrical
Service tech said it would be a week before he can have me in.
Couple of questions for this group:
Is this something a backyard mechanic can fix? Is there something
simple I can check/test?
Will I cause damage if I continue to drive my truck?
If you have had a similar problem (error codes) what was the
outcome...and the cost?
