my 97 e320 has developed a major leak on the transmission.

if i lie under the car(drivers side)...at the transmission bracket...a little cable goes into the trans. pan from the engine side.

this cable has a plastic piece and a hex bolt next to it...it also has a black button that releases a little spring...
the oil is comming out here..

i assumed it was the kickdown cable but it does not move when you push the accelerator.
the winter/summer switch does not move it either...

WHAT IS IT PLEASE GUYS....
