I brought my 53 back from its summer of parades and car shows in Maine. 105 miles and it did really well.

When I parked it I noticed a little oil on the ground. When I looked underneath there was some oil dripping off the tranny.

No oil on the engine and the oil level is down about a 1/2 quart from when we started. After 105 mile I thought that was ok.

The oil on the tranny seemed to be coming from multiple places with the bulk coming off the clutch cover. This is a very small amount maybe a table spoon or 2.

Is this to be expected after a long run (2+ hours)on a truck this age?

I replaced all the external cover gaskets on the engine when I was restoring the truck. I did not replace the tranny gaskets as these did not seem to be as simple.

Is there a seal that I should check on the front of the tranny.

Is it gear oil or engine oil, the smell should clue you in?

I'd first suspect engine oil from the rear main seal, if you have a lower flywheel tin cover then after driving and then sitting for a little while it'll drip out the hole in the bottom.

If you have an original transmission I don't think it has an input shaft seal, while later ones did. Either way it's not so likely to leak unless the transmission is over full or lots of steep down hill driving.

Any leak from the back or top of the transmission should be evident after cleaning, driving, and looking for them.

I think this is gear oil from the tranny. The engine oil is new and so clean you can't see it on the dipstick. This oil is heavy and dark like the gear oil in the tranny.

The tranny was wet with oil all over. I think I will dry it off and see if there are any obvious leaks.

If I pull the clutch cover will I see the rear seal on the engine (at least enough to see if it is the rear seal?

Check the back of the motor above the bellhousing, is it wet there?
