Drain

Fixed with some new piping that hangs downwards till the bottom of the transmission - i later saw that the WIS also shows the driver side drain pipe as hanging downwards and the passenger side as a stub only. (made sense now)
An interesting fix -- thanks. I just looked at my '95 E300, my a/c drain pipes are complete and undamaged, basically a piece of foam tuning with a coiled spring to keep the tubing open. The tubing extends a few inches down from the transmission hump and almost seems as if it was placed so it would drip on the neutral safety switch. I need to figure out how to extend the tubing -- it's difficult to access and I'd rather not have to pull the transmission.
