Our 2005 Dodge Grand Caravan has 89000 miles on it, it has had no transmission fluid changes until today, the dealer did a pan drop fluid/filter change (they got about 4 quarts out). The owner's manual says no transmission fluid changes necessary under normal condition. The service manager told me that Dodge put out a TSB saying not to perform any tranny fluid flushes to service the transmission, only pan drops, is this correct? The transmission has always shifted fine and the fluid looked pretty good before I had it serviced, should I wait a while and have it performed again? Thanks.
