I just bought a 97 grand cherokee tsi 5.2L and it was what seemed like slipping when cold and loss of power when i accel. when warm it shifts better but does not kick down until slowing down or stopping and still feels like loss of power on accel. P.S. I just replaced the fliud/filter today and still feels the same. oh and when changed the old fluid was black and so was filter. ANY HELP IS GREATLY APPRECIATED
Sound lik e aaproblem with Torque Converter, check engine light come on there? I suggest scanned the PCM in order to know fault codes stored there. We have the repair manual, send us details for additional questions.
No check engine light. Its been 2 days since filter n fluid change and it does good when warmed up but still have to accelerate really hard to get going when cold. And doesnt kick down, hot or cold.
Hi, I don't really know if this helps much, but that my on going experience with my '93 Jeep GC, I would say that your problem could very well be transmission; I suggest to read this article:http://www.ehow.com/facts_5073640_signs-...
Your first choice could be make a trans fluids and filter flush and change.
Hope helps.

change transmission fluid & filter

If unit has been neglected, my first thought is serves you right! Maintaining this stuff is essential.
That being said, change the fluid and filter. Use a container of Lucas transmission additive, along with the new oil. Do not expect a miracle. If it does help, change the fluid again in about two weeks. You don't have to drop pan if it has a drain plug when changing the second time. Put additive in on both changes! Likely you have a bad varnish buildup on the insides of the valve body.. you must be a really good tech to take one apart to clean it, so do not even think about it!!! Most shops do not advise changing fluid on neglected units but, if it already is malfunctioning you have everything to gain and nothing to loose at this point!
Good luck

discovered a service bulletin on my Jeep on "Alldata.com", which indicated "A/T - Throttle Position Sensor".I don't subscribe to the site, so I could only see this header. I thendid a search on Throttle Position Sensor and found a number of sitesthat described numerous transmission problems attributed to this sensor.I tookthe Jeep to a Chrysler dealer near me, and purchased the part for$69.00. I installed it myself, and the Jeep shifts beautifully, betterthan when I bought it.
A. The TSB you are refering to is number ATRATB324A, dated 1/1/1996 witrh the subject "A/T - AW4 Throttle Position Sensor (TP)".
TheTransmission Control Unit does, indeed, use an input, among others,from the TPS to determine shift times. So if there is a problem withthe TPS, it will effect transmission shifting. In fact, it is not allthat uncommon to see a TPS cause a transmission problem.
If the transmission works fine after the TPS is replaced then I would only recommend thata routine flush be done to it and perhaps treat it to a new filter.

As far as back flushing goes, that for a radiator/cooling system . The reason I asked about the fluid type and brand is because I have heard of quite a few instances where another brand of ATF3 or4 was used, and same problem occurred, and when they drained the system, and added only Mopar brand ATF3 or4 instead, the problem went away. I'm told by some Chrysler technicians that Mopar fluid has additives that none of the others have in them, that specifically are designed for Chrysler/Dodge transmissions. Other non-Chrysler mechanics will probably argue that, but in my area, the most reputable garages, will use noting but Mopar fluids in Chrysler/Dodge transmissions. Currently they recommend MoparATF4 in Chrysler products. Cost is a little more, but recommended to last lifetime of transmission as well. Whether you decide to try it, is up to you, but if it were me, and I'm not getting any trouble codes to tell me otherwise from transmission, then I'd replace fluid with the mopar ATF4. Might want to have coolant temperature checked as well, if transmission cooled through radiator, and if not, maybe try blocking off external transmission cooler when cold, to see if it helps warm fluid up. Just be real sure to take it out before it gets too warm. You also might want to inquire if transmission places know of a thermostatically controlled valve in cooler to help overcome that. I know they had them years back, as I had one installed on a Caravan, but I'm not sure if they still do.

Hi and thanks for the help. I read the linke you provided and my problems meet all of those for a bad torque converter. But how does a torque converter go bad?
