What is a transmission range sensor?
when the engine is not at temp and I drive in the D position on the shifter I can usually get a CEL and the code comes up as transmission range sensor when I get it checked at autozone. Also when the light first comes on, the torque converter won't lock when it get to high rpm in 3rd. If I turn the car off and then on, it will then lock up but the CEL stays on for a few days. If I let it warm up then drive it I never get the light to come on. help?
