transmission vacuum line hooked direct to line?
 

Here is a good one. 81 240D. The transmission module on the valve cover has been totally bypassed and the transmission module line is teed into the booster line directly. The transmission shifts softly but timely. I noticed a little transmission fluid dripping from the newly installed module at the base where it screws into the tranny? Can anyone tell me what is going on here and what are the consequences of running it this way?

Rapid clutch/band wear from allowing it to slip too much between shifts.

For the 240D the devices on the valve cover actually involve the transmission.

Thank you very much. The car just had 3,000 dollars worth of work to it including a new transmission vacuum module. The car now has been rigged the way I descibed it above. The kicker? The new module is leaking from the inner seal. Does this smell of a shop trying to get a tranny rebuild? If the shop left the seal out and the transmission starts slipping and it was taken back to the shop the shop would say, "Golly, it's slipping and leaking. Must be time to rebuild the tranny." The customer would know no different. Correct?

You'd have to make the conclusion that the shop actually knows exactly how this system works...........a stretch for most of them.

But, as usual, the customer never knows anything.........whether they go to the doctor or the mechanic.
