Check your transmission cooling lines for chaffing
 

Just a heads up to everyone, check your metal trans. cooling lines. On both sides of the oil pan there is a clamp with a rubber grommet that holds the cooling in place. Well, on my TD one of the grommets had become hard a britle and fell apart, thereby allowing the clamp and line to rub against each other. This of course lead to a leak. So for all those out there that have an "older" Benz, check those grommets.

The fix for that if you cant replace the line is take it loose at the cooler line and at the transmission. Clean inside of the line very well with carb or brake cleaner and air pressure. Expose rub in line and get a micro torch , some acid core solder and heat it up ,add the solder to the hole and wham back on the road. Use a small diameter rubber hose between it and the clamp so it wont happen again. ( Had to do this on side of road for a friend one day )
