Don't listen to him you have a cloged govener switch. I work for jeep have a profesionall mechanic replaced the solinoid pack and the valve body and flush the trans flush and put in a new filter good luck it will be a lot cheeper than overhauling the trans.

I have a 1999 grand jeep it cut off when im

I just had this problem on my 1996 Jeep Grand Cherokee. Once the engine got warm, after about 15 to 20 minutes, the car would just die at random times, sometimes when doing 40 mph and sometimes at idle.

I ended up changing the Crankshaft Position Sensor and it cleared the issue.

My 96 Jeep has trouble shifting from 2nd to 3rd gear.The rpms go up to 4500 then it shifts.

That sounds like the 1st thing to check is the transmission fluid.Start the car ,warm it up,now shift through all the gears and stop in (N).With the engine running,check the fluid level.Top up if needed.If you do,look for leaks.Hope this helps

2000 Jeep Grand Cherokee shifting problem from 2nd to 3rd

Check the kick down cable. If it sticks the transmission won't shift. I sprayed WD-40 on both the top and bottom connectors , and it worked like a charm. It's alot cheaper them spending 2000 on a new transmission you don't really need.

1995 Jeep Grand Cherokee chugs after it warms up. I've changed the fuel filter and it is still having the same issue. Could it be some sort of sensor?

Hi G. Sanders,
I have a 1999 Jeep Cherokee Sport which I love and has a K&N filter and approxmately 140k miles. I'm not sure if we are having the same problem but here goes; within a few minutes of cranking up, my Jeep goes through a "chug period" for a few minutes. During those minutes it seems it is not getting fuel.I cannot trust it to pull out in traffic because it seems to lose power during this time as well and sometimes backfires. After a few (maybe 3-5 minutes) it's fine. It doesn't matter whether it's 35 or 95 degrees, it does the same thing. I've had a Jeep "Expert" to look at it and put it on a computer but could not identify the issue. I cannot offer a solution unfortunately but hopefully some Jeep "Angel" can. It is very dangerous and I'm hoping someone can offer some advice. Good luck Jeep buddy.
