Car pops out of D into N under heavy torque - B2 piston?
Hi all,
A friend of mine has a 85 W123 300TD. Over dinner he was telling me how his car would pop from drive back to neutral in high torque conditions (like accelerating into a rotary for example). I have not gone down this route before. Can you help me verify for him that its a B2 piston issue, or maybe something even simpler? I know the fluid and filter need to be checked and changed first. But after that, what could cause those symptoms? Thanks, dd

I'd look to the shifter bushings first before thinking of an internal problem.

That, plus engine and transmission mounts.

this it my bet.
when the vehicle is pulling heavy turns or loads, the engine tries to rotate out of the vehicle, and if the mounts are weak, or gone, the shifter could interpret the twist as a shift...

Thanks guys!
I haven't seen the car in person - I'll have him come by and we will check it out. He will be happy to hear this may not be expensive. dd
