    S Type 2.7 Auto Gearbox Leak

    Hi, I have a slight oil leak from the bellhousing on my auto gearbox (2.7D 6 Speed Auto), suspecting the seal where torque converter slides in, has anyone changed one of these? Hoping its just Gearbox out, pull torque converter out, change seal & back together with new oil & filter. Also have Vibration from Propshaft at 50-60 MPH, but thought while gearbox out could send prop to get balanced.

    Many Thanks

    Chris.

    Took the rubber plug out of bottom of bellhousing and can see where oil has been running down from behind torque converter, I had engine and gearbox out in the summer, to do complete engine rebuild (had snapped crankshaft when i bought it), i didn't take torque converter out of gearbox, thought it best not to disturb, thinking back, the car had sat for 2 years, maybe I should have changed it.

    I think what is more to the point is that if the old crank had snapped in the "usual place" the torque converter itself would have been supported by just the bearing in the t/c. Not designed for that, the seal would have taken a beating. So yes, more than likely it will be just that one seal?

    Good point, the crank had broken near the back, I didn't think of that one.
