[quote=”Doug” post=203606]what actually fixed mine was: there are two identical sensors on the the back side (between the trans and the firewall/ attached to the trans) that have the same identical connection. I had those two connections swapped and didn’t know it. i swapped the two and it fixed everything.

hope this helps.[/quote]

An end to the mystery scooby doo
