If the 3-4 shift solenoid fails, the transmission may lose overdrive completely.To fix a 4L60E that won’t shift out of first gear, follow these steps: Check the transmission fluid level and condition. Inspect and test the throttle position sensor. Examine and test the shift solenoids. Check the vehicle speed sensors for proper operation.When the 1-2 shift failure occurs on the 4L60E transmission, it is usually caused by a faulty throttle position sensor (TPS). It is important to test the TPS for a smooth and linear electrical response over its range of motion. If this fails, then it should be replaced with another known good unit.
