155K miles on 98 s420. When coming to a stop the transmission "clunks." No other symptoms, no slippage etc.

I searched the forum and found another member had a similar problem but no resolution listed.

Any comments or predictions?

I'm betting your flex disc needs replacing. As luck has it I just had mine replaced Friday. Makes a WORLD of difference! I have a '99 S320 with 140K and you just get used to lags and the "clunks" that the wear produces.
The cost will be about $400-$500 at the stealer, but they have to drop the drive shaft, 3+ hour job.
Bottom line: If your keeping the car, get'er done!
