Hi,

My 1982 300td 176.000 miles tranny started slipping badly.
Searched I think all threads about trannys and learned a lot.

Problem started after car was sitting in cold ( freezing) weather for two weeks.
When cold seems to run well. After 3 miles starts slipping. If I can make it into fourth gear it seems to hold up OK.
After tranny starts slipping I had to stop.Whining sound from tranny or converter.
Waited with idle for 10 minutes and car drives again without problem for 2-3 miles.
When it is still driving and I attempt to avoid slipping it shift to 4 and back to 3 and back to 4 very quickly.
Fluid level was to high , sucked 2 pints out and added tranX.
No difference.
Fluid looks good, no burned smell.
Removed 6 bolt pan. Very minor sludge around drain plug. Miniscule brass particles. i would think no problem for 170.000 miles.

My MB specialist says Torque converter pushes liquid out and causes bubbles.

Removed tranny. Pff , more difficult then I thought.
How can I test the torque converter? Does it have a clutch inside?

Can this problem be the B2 piston ?

Thank you for any advice

Johan
