Transmission issues
Hello I have a 1997 blazer with a 4l60e
theses are the codes I pulled from it
po740 torque converter clutch open circuit
po753 shift solenoid a
po758 shift solenoid B
po785 shift timing solenoid
If I pull The transmission fuse it gives me third year and reverse but with the tranny fuse in I only have reverse is there something I can do to fix it or is it just done for? What do you guys think? Thank you

The transmission is in limp mode with no power to it. It will have 3rd and reverse with no power to it by design. You most likely have an electrical issue. Do proper diagnostic on it before throwing parts at it. Could be just a bad ground wire. Need to have it on a live data stream to see if PCM is commanding the correct information.
