G-man Posted June 30, 2007 Share Posted June 30, 2007 I was just under the car with the front wheels on ramps - ie/ the car was on an incline - and I noticed a drip from the rear of the overdrive unit. The car was up for maybe 10 to 15 minutes, in which time it lost about a small 'saucerful' of oil.Since taking the car off the ramp, it hasn't dropped any oil what-so-ever. Obviously not ideal, but how 'normal' is this? Do I need to do any emergency surgery? Link to comment Share on other sites More sharing options...
CharlieB Posted June 30, 2007 Share Posted June 30, 2007 Sounds like the rear oil seal on the output shaft. Mine was leaking as it had become hard & brittle (Spit J type). Link to comment Share on other sites More sharing options...
G-man Posted June 30, 2007 Author Share Posted June 30, 2007 Is it a big job Charlie? I haven't got my hands on a workshop manual yet. Link to comment Share on other sites More sharing options...
trackerjack Posted July 1, 2007 Share Posted July 1, 2007 I think you can just remove drive flange pick out old one and shove in a new one.I have had the solenoid leak in the past. Link to comment Share on other sites More sharing options...

Deleted User Posted July 3, 2007 Share Posted July 3, 2007 rear oil seal is knacked, pretty common, and oil is only forced down the mainshaft to the back of the annulus when the oil pump is running.Dead easy to change, just take off the mounting and jack up the box until clear of the transmission tunnel with prop disconnected.Undo castellated nut by removing split pin+blocking the engine front pulley when in gear, and don't wreck the soft thread, cos the nut is special and unique to the D type OD. take off flange..Lever out old seal and replace, replace drive flange and retighten same way.(I'm a bad boy, have done this by starting the engine locking the nut with a drive and gently letting the clutch in,- German mechanics went APE :o when they saw me use that technique !! don't try to copy me!) ;D Link to comment Share on other sites More sharing options...
