Car is a 92 400E with 722.354 transmission with two leaks on the passenger side of the transmission - the B1 piston cover and the B2 piston cover. Is this as simple as taking these covers off and replacing a seal? I know they're tough to get at but according to lino's recent B2 piston thread the B2 piston is accessible by pushing the transmission over a little. The B1 seems to be as accessible as the B2. The seals are about 4 bucks each. I might give this a try if it's just a matter of taking the covers off and putting in new seals. Anybody ever tried this?

Correction - it's only the B1 cover that's leaking. I guess it's the B1, it's the front one on the passenger side, slightly smaller in diameter than the B2. It appears to be more accessible than the B2 but I'm still not sure if it can come off with the tranny in the car, and if so how it comes off. As Ben Stein, as the teacher in Ferris Bueller's Day Off asked - Anyone? Anyone?

You can get the b1 piston cover out in the car. Remove the rear trans crossmember and wedge a block of wood in between the trans tunnel and the trans to wedge the trans over to the driver's side. I would inspect the bowden(tv) cable o-ring and dipstick tube o-ring as well, these are right in that same area and are common leaks also.
