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

I have silverado 2005....2500hd 6L 8V i just have 1 gear...car have no transformesion and i get code p758 with p2761


p0758 is- shift solinoid B curcuit electrical, TCC pressure control solinoid CKT open,its a possibility that the ignition switch is failing! it shares the same curcuit. the code does not pinpoint the problem it just tells which curcuit its in. so testing is needed to verify problem. GOOD-DAY!

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!
