Hello,

I have a relatively new to me 2006 LJ automatic with 150k miles.

I experienced limp mode issues after driving for 20-200 miles each time. Parking and turning the car off for a few minutes will return things to normal besides the check engine light.

The transmission shifts nicely during the time up until limp mode engages. I do not have hard shifts when cold, and motor idles nicely.

I just replaced the fluid with fresh ATF+4 and new mopar filter. Fluid level was checked correctly. Symptoms remain.

Has anyone else experienced similar codes and resolved them?
