After driving 2002 Chrysler Town and Country EX at hwy speed for 1+hrs, experienced a "jerk and sharp rise in rpms" consistent with "slipped gears." After pulling over, shifted to park and back to drive and no engagement; checked other gears and no engagement; same upon engine restart. Checked tranny oil - level and color appear normal. no sounds or vehicle movement when going through gears.
manual key check revealed codes: p1684 and p1698. disconnect battery and wait 10min did not help (but cleared p1698 code.)
owned last 2 months and have not experienced any difficulty with shifting (or anything else;) trans oil changed mid-nov.
last august the previous owner had the tcm replaced with one pulled from another vehicle when their vehicle went into limp-in mode without warning. the shop that did the work advised the owner to take it to a dealership for programming so the mil would go off and prndl would display properly.

But I am afraid I can't tell you want all these codes mean for your car. It was probably not related to the change in fluid that was performed. However, it is serious and should not be driven until fixed. Risk of total destruction of the transmission is too great. I would assume the symptoms are so diverse that it may be a bad transmission control module. Which is about $200, and fairly easy to replace:

But there are other possibilities, such as a bad relief valve could be letting main pressure drop too low.
This is the type of thing which does require an expert and can't easily be done remotely.

you cant get rid of the issue until you find the cause and fix it. i would not recommend throwing any more parts at it, get someone with a scan tool and see what codes are there before you waste any more money

I am hoping somebody could point me in the right direction. First shop it was towed to told me to take it back to where tcm was put in. Checked with that shop and they told me to bring it over for a check. In a week it has not moved from where the tow truck put it down and the only thing I was offered was to have the tranny taken out and rebuilt. Nothing has been checked; the hood was not even raised. Any suggestions? Now preparinig to have it towed for a third time; this is getting ridiculous!
