Hello all- this falls under "service" I guess. I have an '02 Montero Sport XLS 2WD that has been our family truckster for 10 years now. It's recently been retired to a backup role due to needing a transmission rebuild. I gritted my teeth and paid for it, since all the rest of the car was holding up pretty well. Then had to take it back again, bad brand new valve body, OK, whatever, it's under warranty and they'll handle it.
Just got word that they're almost done buttoning it up a third time, second time they've attempted this specific repair (first time was a total transmission rebuild, new valve body and torque converter too. Second repair tried a new valve body, since it wasn't quite right. Third trip was apparently the same thing- replaced the valve body again just now...). Labor and parts are covered under warranty, but I'm putting miles on my backup vehicle waiting on this thing to get out of the shop, plus the general PITA of trying to get it dropped off, picked up, etc., etc., etc.
I guess this is about 50% rant and 50% "has anybody else had this trouble?" Car was pretty much fine until 125k, at which point these transmission troubles started. I was hoping to get this thing to 200k miles before trading it away on something else, but if it's down repeatedly with transmission problems that'll never happen- I'll wind up having to trade it away before something else breaks.
Transmission guy says he's hearing this is relatively normal for Mitsubishis, apparently there are just zillions of valve bodies out there with a defective casting that makes them not work quite right. We must have been "lucky" to get ours to 125k.
