Hello fellow Forum users. Can anyone tell me the correct torque settings for the 12 bolts holding the sump pan onto my '72 3500's BW35 automatic box? I'm experiencing fluid loss from the sump pan, so I gave the big end of the motor and the underside of the gearbox a clean to see where it is coming from, and it looks as if the sump pan gasket is leaky almost all the way round. The visible edge of the gasket is suspiciously clean and pinkish/orangey and new looking; perhaps it was recently replaced by the previous owner and just not tightened up suffieciently!?
I'd like to just nip them up tight, but although my Workshop Manual lists torque settings for the BW65 it gives no information for it's clunkier predecessor! Previous posts regarding dripping BW35s suggest this is a common problem, can anybody shed any light on how they've rectified this?
Further, if I do end up having to drain the autobox and remove the sump for inspection, given that the Torque Converter will retain fluid, how much new fluid should I pour in before I can run the car for the recommended four miles (to get the box up to normal operating temperature), before finishing the top-up to the correct final amount?
Any help, especially info on the factory quoted amounts of fluid (incl. & excl. Torque Converter) gratefully recieved, I'm a Luddite not a mechanic!
