the gm180 box in my T Bucket is dribbling from the opening in the bell housing, is there a seal that is in there between the box and engine? its not a mega leak but its annoying having to keep a tray underneath in the garage.
cheers

There is a seal on the input shaft - but of course you have to remove the box to get at it.

Do make sure it is actually coming from that rather than from one of the more common places (easier to fix too) and just running down to the bellhousing.
The most common places are the filler tube entry, kickdown cable, and selector cross shaft. All at or near the top of the box. Check it isn't damp around there.

You can make an informed guess by when it looses fluid. If it's mainly when stopped, it's most likely to be the common ones as the oil level is higher when stopped. If it looses fluid during a long journey, could well be the input shaft seal.

hi folks first post here, ive pulled the engine and box apart to find out where its leaking from and please see attached phot. i suspect that its the seal at between pump and bellhousing, what sort of a job is it to split the 2?
