Twice on the same vehicle? That's terrible.
First time was in a small town in KY, I lost reverse backing the TT into a campsite. GS sent a guy that used his flat bed to finish backing the TT into the site. No transmission shop in town, so only option was Jasper rebuilt from local garage.
Put about about 10k on the Jasper and the 3rd gear sprag grenaded towing the TT in NJ. Jasper replaced under warranty but still cost $900..some of that was for parts that were "not covered". Plus the friendly garage pointed out that the Jasper warranty pays $65/hr labor and his rate was $110/hr, so that made up a large portion of the bill....
Point being that nobody expects a trans with a fresh rebuild to snit the bed, so all the preventive maintenance in the world is no guarantee of anything. Yes it stacks the deck in your favor, but stuff happens.
