Hi guys. I´m from Sweden so you have to bare with my english.
I have a 1996 Chrysler Vision Tsi 3.5l Limited Edition, or I think it is a 1996, but the engine might be a 1997, because only the 1997 waterpump fits. The 1996 waterpump doesnt fit the engine.
It has A/S and everything, except heated seats. It is a importcar from Germany.
My question is if a Prowler TCM will fit my car bolt-on, and where I can find a Prowler TCM, nad of course, what it will cost.
My tranny has a weird problem right now (I have not had the time to change oil and filter yet), it shifts hard from second to third, and it does a "bump shift" when I slow down to stop at a red-light. Like it doesnt know which gear to shift into. Same if I drive at a speed of 60kp/h and step on the accelerator to pass another car, then it will downshift, but sometimes it can take a amount of time before the tranny can decide which gear to use, and meanwhile that time, it stumbles/stutter and wont provide that extra power that i need to pass the other car.
Does my TCM have to be resetted/relearned or can it be the oil or filter that has to be replaced?
While I don't think your issue is the TCM, technically it should be compatible as the Prowler uses a slightly modified version of the 42LE. I would not, however, look in that direction. When changing a TCM (or a transaxle) you should have a dealer clear the CVI table (clutch volume index, it lets the computer keep track of how much fluid is required to actuate the clutch packs). Out of whack CVI values will throw a wrench into things and while I think the TCM can learn new values over time, that's not a given and correct procedure dictates having the CVI values cleared.
Now, on to your problem. I would look at fluid, filter and o-ring. The transaxles in these vehicles are particularly sensitive to fluids so ensure that you always use ATF+4. I even tend to only buy the Mopar branded stuff, there are other brands, but I think it's best to go with the genuine product. I would replace the filter and o-ring and clean out the pan sump and replace the fluid.
I would do that, and ensure that your fluid level is correct first before continuing any diagnostic. Some might say that you should just check your level, and while I would tend to agree, there is a strong likelihood that your transaxle is filled with ATF+3 and ATF+4 has a more up-to-date fomulation so it is a good upgrade regardless. If other people have serviced your vehicle it is possible that they used the wrong fluid altogether, like Dexron, and if thats the case, you want all that shit out of there ASAP. In fact, I don't know if there would be any salvaging that transaxle short of a complete rebuild if that is the case, but if you have a chance at all, it starts with removing all of the contaminated fluid - and in the even of improper fluid fill, I know of very few ways of ensuring you are able to completely change the fluid out aside from diluting it with several changes, and that could get expensive. Some have recommended Jiffy Lube type flushing, and in the even that you KNOW the fluid has been contaminated with a non ATF+3/4 product, then I would say it probably couldn't hurt, but otherwise, I would recommend staying away from that procedure, others may disagree though.
I would definitely list the fluid and filter as a possible reason to your harsh shifts. If a filter is getting plugged it may not allow enough fluid flow to fill the clutches as quickly as it should; resulting in the clutch packs for the current gear draining at a normal rate, a hesitation (neither clutch pack transferring power), and then the clutch pack for the intended gear engaging. Not saying that this is necessarily the problem, but is a possibility. And probably where I would start if the fluid and filter have not been changed recently.
Yes a Prowler TCM will work, but only from a 97. They are great but not without faults. However not cheap at all. Look towards atleast $600 plus for one if you can find it. Only people that I know of to ever have tried a Prowler TCM in a car is ACR, Chewievette, and Me.
I would start with what these guys were saying, the right fluid, a good filter then see what happens.
