I drive a 2000 Jeep Cherokee Freedom edition and on my way to work this morning I noticed my check engine light came on, it drove fine until I reached the highway, it's an automatic transmission and everything is smooth sailing until about 55 mph where it will normally shift and it no longer does. This is my first jeep and don't know much about it. I was wondering if anyone has had this issue or has any advice? Thanks

check the TPS!!

I had the exact same thing happen to me. I thought I lost 4th gear.
simple 2 minute fix. TPS is about 50 bucks.

spring in the TPS my be stuck or the points inside might be bad.

my OBdii reader could not pick it up but a friends did. his actually read the voltage from the TPS and it was not working.

again no problem!
great to hear all is back to normal!
I can ONLY imagine the thoughts going through your mind, thinking of doing a rebuild on the tranny :eek: as I know that was running through my mind when it happened.
little help from web surfing and board members and I was back up and running.

cheers
