1st gen LH, 42LE trans. it's in limp-in mode. getting code for the output speed sensor. went ahead and changed it since its cheap. changed fluid and filter, cleared codes but still in limp mode. need to check signal to the sensor and ground. both wires to it come from the TCM. but, i cant find any info on the signal IN. is it 12 volts? 5 volts? is it a constant signal or a pulse? need to find out what to look for.
Alldata also tells me there's a fuse for the TCM in the power distribution
center, but there doesn't appear to be.
