#856 of 1101 2006 JEEP TRANS PROBLEMS
Sep 19, 2011 (7:01 am)
This is my second Jeep. My firt 2001 Laredo experienced locking or freezing of the suv. Very scary-driving down the interstate when your SUV freezes and you have no power OR control,- no power steering and you have to pray and glide to the side of the inner side of the HWY. This happened to me 5 times.
I traded it, and bought a 2006 Laredo and thought my problems would be gone. Just the start! With 60,000 miles on it I have the transmission light going off and the system goes into a slipping out of gear or a revving. I have to shake the gear knob to get it "out" of the malfunctioning mode!!
I have read a lot similar problems! Besides this not so scary problems, are the following; the seat belt light is on with the !#$% chime on, the air bag light is on, the check gas cap is on, and my low tire light is on. Believe me, my husband has checked all four tires with the gauge, filled them properly and there is nothing wrong with the tires! I will never ever buy or suggest a jeep to anyone! I hate chrysler and believe me they are aware of these problems.
Today I am on my way to shop to see what they can or can't do to the jeep. Last time when I had the trany light problem the shop said well it isn't on now! Well that is murphy's law! It was on all the way down 44 miles to service shop but then when the crap JEEP is being looked at, the light isn't on. I guess the light has to be on! This is a nightmare!!!!! Well today Sept 19, 2011 I am taking it down for the oil change and they have check out the problems. I said to them they are keeping this jeep, pronounced HEEP in our family, until they figure out what is wrong.
NOW THE SECRET. it is called the secret hidden warranty. PLEASE CALL
1-800-992-1997 Chrysler covers the four-speed automatic transmissions from some years through 10 years or 100,000 miles.
for any JEEP ISSUES. I called today and Kelly customer service said that they do not have records of my transmission light and slipping issues on the 2006 jeep 60,000 problems. Then she said, "do you want to be transferred to the service contract warranty department?" Yes I do!!
Spoke to the service contract department and this is the following info. On my particular SUV-VIN # GIVEN- I DO HAVE THE FOLLOWING WARRANTY up until 80,000 or MAY 23, 2014.
My service contract will cover the following:
transmission case-internal parts
transmission control module------ PROBABLY-THE CULPRIT IN MY SITUATION
Transmission range switch
seals and gasket for the listed comp above.
CHRYSLER needs to know. about these problems CALL THEM AT THE 1-800 LISTED ABOVE
I hope this is helpful .

Runs good. Does not slip when changing gears. however...riding along at 60-70mph the rpm goes up and down between 18-20. when climbing hill it downshifts fine and stays steady until you get back to just riding along 60-70 mph

I suggest you analyze how the engine or engine computer is feeding information to the transmission. If the transmission has a computer and talks directly to the engine computer (digitally) then you will have to look for a sensor being used by the engine computer for that purpose. Look for any fluid or oil leaks that may have contaminated the sensor or wiring at the transmission. One problem with oil leaks is they blow back on the transmission. I lost an oxygen sesnsor that way.
If you see any wiring or a sensor covered with oil, repair it.
One other thing you should do is check all the ground wire connections for the transmission electrical components. Get an ohmeter. One end should be conntected to negative terminal of the battery. It should be 0.00 ohms. Set your meter to this scale. Good luck. My guess is transmission thinks engine activity (example throttle) is changing when it really isn't.
#859 of 1101 Grand Cherokee transmission problem
Oct 10, 2011 (3:52 am)
Hopefully someone out there can help! I have a 4.7lt 2001 Grand Cherokee 150,000 miles on the clock and have had problems with the gearbox when the engine warms up. From cold until say 20 miles running everything is fine and then it drops down into 3rd gear with no response then from the overdrive button. When cold this is not and issue only when it warms up. The jeep dealer cannot find any fault on his diagnostic equipment and has basically washed his hands of it! I have been told to check the grounds which may be losing contact when the engine warms up but they all appear to be fine. Has anyone any experience of this please??
#860 of 1101 97 Jeep Grand Cherokee 5.2 2wd shifting late
Oct 10, 2011 (5:23 am)
I have a 97 Jeep Grand Cherokee with a 5.2 and 2wd that has about 145k on it. Over the last 6-8 months the Jeep has started to shift later and later. It is now at the point that it won't come out of first gear till a little over 3k rpms. Second is the same but shifts a little sooner, maybe 2800 or so. 3rd to drive is fine, drive to overdrive is fine. This started with the transmission bouncing between 1-2 when accelerating hard in city traffic. Highway speeds it runs good, other than the occasional shudder when climbing slight inclines. The shudder is not my main concern at this point. The fact that it's not shifting is KILLING the gas mileage. Just changed Tranny filter and fluid about 8k miles ago. It helped some for a little while, now it is right back to where I was prior to changing filter and fluid. Someone told me it could be the shift packs in the transmission. I am a decent mechanic just don't know much about the new transmissions with all the computer involvment. Any help would be great. Don't really want to take it to a shop and pay $300 for them to look at it and tell me it's going to cost me $1500 to fix something that I can do myself and show my sons how to do in the process. Thanks for any help in advance.

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.
