4L65e won't shift
#1 · August 20, 2022, 2:18 pm
Tranny has been shifting great, tried to reset IAC, won't show gear position on hand held. It won't shift out of low. I checked all of the connections. Any ideas?

I found out this morning that there is no speed registering on the hand held. I changed the VSS, but that didn't help.

After driving the car for three weeks, Fitech tells me I don't have the correct sensor. Bought the one they wanted, still doesn't work.

Sent the ECU back to Fitech, waiting for an answer.

Have you checked to make sure in the initial set up menu under transmission that the 4lxo is check and not other. I ran into this issue and mine did the exact same no shift and no speed also didn't show the selected gear.
