How do you adjust bands on GM TH-125 transmission?

To adjust the bands on a GM TH-125 transmission, first, ensure the vehicle is safely raised and supported. Locate the band adjustment screws—typically found on the transmission case. Using a socket or wrench, tighten the adjustment screw to the specified torque, usually around 15-20 ft-lbs for the front band and 10-15 ft-lbs for the rear band. Always refer to the specific service manual for precise specifications and procedures for your vehicle.
