We have owned this 2003 Grand Caravan (3.3L, 4-speed OD transmission) since new. It has 105K miles. Over its lifetime, I have changed the transmission fluid and filter twice (once at 30K miles and once recently at 105K miles). It has never had any problems with the engine or transmission.
A couple of weeks ago (before the recent filter and fluid change) we backed out of the garage. Upon putting the car into Drive, the transmission did not engage. It went into neutral. After a couple of shifts back into Reverse and then Drive, it shifted. It has not failed to engage since that time, which would be dozens of occasions.
But since that event, the downshift from OD to 3rd has been very rough. It's not quite a "clunk" but a definite "crisp" downshift. The corresponding upshift is very smooth, as are all the other downshifts. Does anyone has an idea what might be going on? Thankfully it doesn't seem to be worsening, but on the other hand it's not getting any better.
Thanks for any insights! Craig
