Sluggish Transmission on 1997 Chevy S-10


Here's the information on your trouble codes (which explains the problem you're having).

P0740 Torque Converter Clutch Circuit Malfunction
P0753 Shift Solenoid A Electrical
P0758 Shift Solenoid B Electrical
P0785 Shift/Timing Solenoid Malfunction
P1860 TCC PWM Solenoid circuit electrical

The good news is that it is an electrical problem rather than a mechanical problem. So, you should be able to get the problem taken care of without removing the transmission. The bad news is, you'll probably have to take it to a tranny shop to get the electrical bug worked out (unless you have the knowledge/equipment to test each of the electronic components of the tranny).

Hope this helps and good luck!
