SOURCE: Trans stuck in 3rd gear, key won't come out of ignition.Check eng light is on.

The most likely cause of this condition may be a loss of voltage to the transmission on circuit 1020. This loss of power may be caused by an open in the ignition switch. This condition my also be the result of an incorrect installation of an aftermarket electronic device such as a remote starter or alarm system.

You might want to check for a mouse nest under the Underhood fuse block, seen them chew up wiring under there many times.

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!
