Sudden Decelleration 2010 Jeep Compass Sport 4WD 2.4L 117000 Miles Sign In

Driving home going about 45 MPH suddenly the car decelerated to about 20 MPH and with the gas petal on the floor it would not go over 25 MPH the tach was showing 4500 RPM's check engine light did come on. Got home the car set overnight next morning started the car to take to my mechanic car ran great no problems. Only code was for "engine misfire" they keep the car for 2 days drove it several times nothing happened. No idea what had happened maybe a random event. The next day I had been driving for a few hours and it happened again. I was able to pull off the road turned the engine off and after about 10 minutes or so turned the engine back on put the car in gear drove off everything was fine. Drove the car for the better part of a day it happened again. Shut the car down waited about 10/15 minutes drove off no problem. I am afraid to drive the car because the next time I may be on the expressway 70 MPH and I could have a serious problem. When I say sudden deceleration the first time it went from 45 to 20 in a heart beat I mean right now. Any thoughts would be appreciated.

Sounds like the transmission might be going into limp mode due to an internal issue. You need to have the codes read in the TCM, not the PCM.
