It was the mechatronic sleeve. Total bill was $474. I paid $100 and the warranty paid $374. Thankfully the warranty paid for all new tranny fluid. So, I coughed up an extra $305 for a new oem pan/filter combo. It was a little more than Tischer's discount price, but hey, what are you gonna do? The mechatronic sleeve part was only $30. 6 units (liters or quarts?) of fluid at $20 per, 3 hours of labor at $97 per.
