Car transmission issues?

Question

Hello I have a 2003 jeep liberty special edition with 450k kilometers and I am having what looks like transmission issues. Whenever I'm on the highway I like to put cruise control on at 100 and accelerate with the hand accelerator. I've noticed that when I push the hand accelerator to go to 120 the car feels like it is going to fail. It feels like it is having a hard time changing gears like it's struggling but when it finally does change it revs up to 5-6 rpm for about 3 seconds, This also happens when I use the pedal too. it feels like it hesitates to change gears.

That's probably a transmission control issue. A bad TPS can make it act like that.

Answer 2

450,000 km is your answer. The transmission has probably had it. Check the fluid for discolouration and/or a burnt smell.
