Hello; I am new to the site so I hope I am in the right area.
I am getting the PCM 0734 code which indicates a 4th gear issue. I had the car checked at the dealer and at a transmission shop. Both said nothing wrong with the transmission and the code was cleared. This done about 2000 miles ago. Now the code is back, the transmission shop says it is an electrical issue.
Anyone have an idea what I should check next, as to wiring harness or ground issue?
