Transmission Filler Tube Housing

I've got a leak at the base of the filler tube on my 1985 190E. Is there an O-ring down there?

Yes. Loosen the flange bolt (small hex, I think) and pull housing out, slip on new o-ring and voila! good as new (atleast mine is, good luck).

BamaMan,

Glad you replied. Been trying to contact you regarding the R&R. The 5mm allen bolt is a PITA to remove because of the clearance between the cooling line and the exhaust shield. Did you have to remove your cooling line? I might have to in order to get enough torque out of the itty bitty allen wrench.

Is there not room to use a 5mm allen key socket and rachet wrench?

MikeTangas,

Ahhhh, yesss. Good idea. Thank you for the enlightenment.

Not sure about your car, but my AT filler tubes are clamped to the back of the engine a few inches from the top end fo the tube.

Same here, Sixto. The brackets support the filler tube so it doesn't warp at the base housing.

Good news!!!

I finally stopped the leak from the passenger side of the transmission on my 1985 190E. The filler tube O-ring was the culprit. Thanks again to all the forum members for their contributions! I had to remove the cooling line in order to get enough clearance for the 5mm hex bit socket and ratchet.
