Should I service Transmission @ 219,000 ?
I would never Flush the trans with that many miles on it, you'll find out your ok trans is a piece of crap and have to rebuild or replace it. Just do a simple fluid and filter change on it with some ATF+4 fluid which is still being made cause dodge is still making cars and trucks that use it.
I'm not going to go Viper on you, but since you have more experence than me, tell me accounts that you know of transmission damage because of being flushed...
Actually, it's well documented, especially with higher mileage vehicles that were poorly maintained. Places like Jiffy Lube here have been busted for convincing car owners that it is a normal manufacturer recommended service (it isn't). Just like fuel injector flushing, it's a scam. In the case of older trannys it can do more harm than good, but the problem is that the damage may not show up for a couple thousand miles, so the car owner rarely connects the flush to the damage.
