I have 120k on my original transmission, and so far the only thing I have wrong with it is a sticky TCC solenoid and a dipstick tube that is cracked at the base (my own fault). Our transmissions are not the easiest or most straight-forward to rebuild, plus a lot of places that rebuild them only replace the wear parts, and not necessarily the sensors/solenoids that control them. Personally, I would buy a transmission from Trannyman (tripleedgeperformance.com). That's who I'll be getting my new one from when the time comes to replace it.
