Have a 2008 Chrysler Aspen with P0765 Code from hell

Tech over kill , The problem could be anywhere in the wiring , The systems are so complicated you'd need a technician that actually cares to trouble shoot it . If the next tranny doesn't do the trick then I hope you've learned what cars NOT to buy . Drive around town till some idiot runs into it and you can collect the insurance money , should take a week or two

Shift solenoid D under drive on/off po765 is there an accompanying codes? Po700 or po888 look up ground connections for shift relay, once located flip fuse box over w a test light on the shift relay,connect clamp end of test light to known 12v-+ probe ground wire, should be black w a red stripe, traced out it will be in one of the main ground clusters on body should be the only wire w red on it rest In the group should be black w white stripe or solid black. Chryslers share this common issue. If wire does not test out you can fix it by completing circuit bypass, direct to ground, please pull wiring schematic to verify location and wiring color.

Ps shift relay completes ground to pcm for triggering next gear range. No signal or intermittent signal will give these kind of issues
