anyone?

 

Yes there's a computer just in front of the shifter underneath the radio. Un-plug it, and it will force the transmission to run manually. 1 shifts 1, 2 shifts 3, and D shifts OD. That will allow you to narrow it down to mechanical or electrical.

 

the other day mine wouldn't come out of park unless i used the unlock button to shift into gear it was dark couldn't see . next mourning i took the cover off and cut away all the small filmy slips. low and behold some of them had broken and lodged between the lil pin
fixed

 

mine doesnt have any computer in front of the shifter under the radio i took everything out any other ideas im at a lose does the ecu control the transmission on this model?
