I heard a lot of that.  We had at least three and others we know had them and I never heard of one having the problem until ours.  Now, we had lots of miles on that vehicle (well over 100K).  I don't doubt that there were plenty that had problems, but they also sold a lot.  At one point (and perhaps today) they had over 50% of the minivan market.  Just about every family where I live had a minivan and a sedan, at least.  It would be interesting to know what the relaibility numbers really were.

When I had the transmission rebuilt for my Dakota, the shop owner told me without Chrysler he would be out of business. If regular maintenance has not been performed, every minivan needs a new transission at 80,000 miles he tells me. So I asked him, why do carmakers design transmissions that cannot be drained and put filters where they are not readily changed?

my experience is with older cars.  We had a similar car (a Chrysler Town & Country) which had the transmission fail (after 12 years).  We decided not to fix it (it was my wife's car and she needed something right away).  It might have been interesting, though.

Nope.  That is one thing that is sort of on my bucket list of car repairs.  I have done more car work than I would like to admit, but I have always stopped short of pulling an automatic.  I have done manual's, way back, but never an automatic.  Looks like a swiss watch.  One of my co-workers fixed his Chrysler Caravan transmission, and he was quite pleased with his accomplishment.  It had one planetary stage froze up, I think.  It took some effort, but he got it going.

ttemple, correct.  Have you ever tried to repair one?  It is a real trip.

I would say that almost every modern automatic transmission has several planetary stages.

Kevin, I have often admired planetary gear arrangements.  They look complex and are strangely beautiful compare to other mechanical systems.  If I recall correctly, the Toyota Prius synergy drive system uses planetary gears systems.  Is that correct?
