I've got a 2012 Dodge Durango SXT with the V6.  Overall it has been a pretty good vehicle.  I bought it brand new for the wife, and both my son and daughter have used it as a daily driver.  It now has 248k miles on it.  I got a call from my daughter this evening and she said when she put it in drive it actually went in reverse.  She put it back into park, shut off the vehicle, started it back up, and it worked normally.  Any ideas on what is happening here?

According to Chrysler, you are 230k overdue for a tranny replacement!

Jk! Good luck.

Sounds like stretched/slack shifter cable & worn bushings,

Could be that and iirc they got a transmission sensor that tells it what gear it should be in.

Hook it up to code reader, should give code(s) if sensor is issue.

Eta: first thing is check fluid level, make sure it's not low.

I had a 700R4 that started acting like it was in drive and reverse at the same time.  I got about 400 miles more out of it before it destroyed itself.  This was a low mileage trans.

First thing I would check is the shifter and cable for slack or worn parts.

Hop underneath it and have someone shift through the gears.

No transmission codes.

OP, since it is a physical cable, it may also be the linkage for it inside the transmission or the spool valve itself. Most likely it is the linkage, which will be a very simple little piece, IF the cable and shifter check out.

I'll have to crawl up underneath next week sometime.

I just finished up replacing the cam and lifters in a Dodge Charger RT.  I wanted to take a break.

If memory serves me correctly, coworker had this issue.  Something about a small plastic clip that just gets brittle over time and breaks. Cannot remember if it was at the shifter or under on the trans.

Replacement shifter cables are under $40.  Maybe that's my future.
