To start with, your Jeep dealer has very little interest (read motive) in getting a Jeep with 150,000 miles fixed. My advice would be to ignore him completely. I had a similar experience with my 1998 Cherokee where both the dealer AND a transmission shop said nothing but a rebuild would fix my Jeep. Neither one could remotely say what the problem was....they were clueless. With nothing to lose, I checked it out myself, found the problem was a bad solenoid valve, fixed it and I am still running it today. That was back in 2009, so in other words don't become discouraged.
I'm assuming you've already checked obvious things such as fluid level, leaks and electrical connections. Sometimes the prongs inside electrical plugs lose their "spring" and don't make good connections like they used to especially in high mileage vehicles. It happened to me with my Throttle Position Sensor. I blamed it on a bad part only to find it was the electrical plug itself.
Since it's temperature related, that implies it could very likely be electrical (switch, sensor, solenoid valve, etc). First thing I would check is the engine temperature sending unit. Your Jeep might have more than one so check that out. Another thing to rule out is the Throttle Position Sensor (TPS) as that would be suspect at such high mileage.
I assume yours has the 45RFE transmission which includes a temperature sensor inside the transmission. That along with the solenoids in my opinion should be checked out after you've ruled out anything external to the transmission.
Above all, don't become discouraged talking to other people about your problem because I haven't found many interested in this type of subject. Good Luck!

Make sure you have 0 and I mean ZERO transfluid leaks. The cooler lines should be bone dry. My 97 jeep was acting funny and I replaced the cooler lines and it fixed it. My guess is that transfluid leak affects the pressure somehow.
Adjust your band if you have an adjustment.
Drop pan and replace filter. If you let it sit a couple of days without the pan you will get more fluid out of it.

I recently just purchased a 1996 Jeep Grand Cherokee Laredo and it ran great all the way home, but just recently its been giving me some problems. It has trouble downshifting on the highway which makes it almost impossible trying to pass people. Also, when starting from a stoped position it takes a very long time to get up to speed exspecialy when trying to climb a hill. The person i bought it from said he recently put a new tranny in it, so I'm very confused on what is causing this power loss.

Can you force the tranny to shift manually?

Is this on a 6 cyc engine? Sounds like linkage is not adjusted right. There is a button on the throttle linkage that is adjusted to sync the throttle position with the transmission...pretty easy to do. If you have a 6 cyc and can get the manual it is no problem to do yourself. I just had my trans replaced and did not have a problem but I remember there is that adjustment.
Also might find out where the transmission work was done and take it to them. If they are a reputable shop they should stand by their work and tweak what is not working.

#870 of 1101 2001 jeep GC. LTD. 4.7, 45rfe tranny problem
Oct 18, 2011 (5:23 pm)
My 01 jeep GC tranny seems to work fine except when stopped or almost stopped. It acts just like a standard tranny would if you didn't engage the clutch when stopping, it started doing this after vehicle had sat for 2 or more weeks. This happens in all gears including reverse and it is intermittent (but getting more common), even after shutting off or stalling motor and re starting. I believe the torque converter is staying locked up. 1. has anyone experienced or heard of this? 2. Is this common? 3. What am I looking at to fix it? Is it a solenoid problem, valve body problem, torque converter problem, or a control box problem? Any help would be much appreciated. Thank you very much, 72marquis

I have a 2001 jeep grand Cherokee Laredo 4wd 4.7L v8 with 107,000 miles when it shifts from 2nd to 3rd at lite or normal throttle it shifts hard but if you are accelerating hard it shifts fine the transmission is a 45RFE the hard shifting is after i have drove it for 20 miles or so the temp is around 190 top 200 2nd question is there a check engine light or is there just check gages & trans over temp lights
