Hello.

Ive noticed on my 92 400E, my 3-4 shift under moderate acceleration slips a little bit. But, under normal acceleration, its nice and firm like the other shifts.

Ive tried boosting the pressure a little bit, and it helped, but the 3-4 shift is still weak in comparison.

Could this be the B2 piston failing?

How much clearance do you need to remove the B2 Piston? Could you "convince" the tranny to move enough without stressing anything?

Thanks for advice. Car has 120K on it.

Andy
