Not sure what's going on with Jeep the dealer told me they couldn't find anything wrong with it but maybe someone here has encounterd this.
2004 Grand Cherokee Limited V8 Automatic- 66k miles.
Issue: Was driving in Massachussetts last week on a highway and I ran into some traffic. I slowed down below 10mph and as I went to speed back up my car wouldn't change gears and my temperature gauge went right to the red line but my engine wasn't overheating. I got home and the next day I took it to the dealer. They had it for 2 days and said there was no issue. I picked it up and later in the day the same issue happened except I could change gears but the car was very sluggish doing so and wouldn't speed up as well also the heat wouldn't come on. I got to where I was going and the temp. gauge was reading near the red line and the check gauge light came on but again nothing was overheating (ie no smoke). Then this morning as I came into a yeild as I entered a rotary and I hit the gas and my car woulndn't move, then after about 3 seconds it was like I was shot out of cannon and it sped up way to fast. It did this about 3x as I stopped at lights etc. Anyone have any thoughts on this. I'm weary to take it back to the dealer and pay the diagnostic again.
