Between January 1989 and July 1991, Chrylser tried 28 different changes
to deal with Ultradrive problems. In 1991, after much pressure from the
Center for Auto Safety, Consumer Reports and others, Chrysler promised
to waive the $100 deductable in the warranty, provide loaners, and buy
back any cars with Ultradrives that could not be fixed. Chrysler ran an
unprecedented campaign to contact all owners of cars with Ultradrives
to find and fix problems. 

In 1992, the A604  was renamed the 41TE transmission. Service bulletins
after this date refer to the 41TE even if they are covering the 1989
A604. It appears as if the name change was an attempt at avoiding
further negative publicity rather than a major new transmission.
Indications are that the 41TE is failing at an alarming rate.

There are at least 32 TSB's covering various problems on the A604 and
41TE transmissions. For vehicles with poor shifting or transfer gear
whine, the TSB's should cover the problem. For vehicles which lock into
second gear (limp mode), you should not pay for any repairs or
replacements, the dealer should bill Chrysler. Contact Customer
Relations or your zone office if your dealer refuses to perform repairs
without billing you. If this fails, go to small claims court or hire a
lemon lawyer. Be persistent and force Chrysler to take responsibility
for its mistakes.

The following list is TSB's covering 1992-1995 that I know of.
