Thanks Guys! The car is up in the air now and I'm looking at it. On this model ('95 E320) there is a heat shield behind the engine that blocks access to the two uppermost bolts that hold the transmission to the block. Is there a trick to get to those two bolts to take them out without removing the heat shield? The right hand bolt also holds the filler tube. The book only says

etach and remove from engine. All other fasteners are accessible.
