Help with 1970 280 Sl Tranny leak
 

I have a 1970 289 sl roadster in line 6 automatic. Its leaking between the tranny and the torque converter. is their a seal bewteen.? Also leaking oil between egine and torue coverter. How hard is it to pull ythe tranny off I need some advice not to much familiar with mercedes thanks

The front pump has a rubber o ring; the pump has to come apart. Pump, torque converter seal, easy to change and a pump gasket. If you have no transmission experience, learning on a Mercedes can be very costly. More often then not, the o ring is leaking.

Seems that some also had riveted fluid coupling front hubs that leaked. I actually use to TIG weld them up. Have probably done 5-6 successfully. Used to be a pretty good welder before bifocals.

I just repaired a leak on my '69 in July: http://www.sl113.org/forums/topic.asp?TOPIC_ID=5373. It isn't too difficult. Getting to a couple of the transmission-to-engine bolts was a bit of a fuss. I have a tip for getting the top-most pair of these bolts. Remove the carpet over the transmission tunnel to reveal an inspection plate at the top of the tunnel and another on the right side. If you remove these plates you have easy access to the bolts.
