Thanks...Moved to 262/4.3.
You can pull the inspection cover on the trans and look up in there and see if it's leaking at the rear main.

Whats it look like and how does it come off?
If you look at the bell housing, there is a silver plug....not very big, but it pops out.Whats it look like and how does it come off?
If it's black it's your rear main seal unless the oil pressure sender, intake gasket or valve cover are leaking bad enough to run down there.
If it's reddish the front seal of the trans is leaking. To repair either the trans has to be pulled and if it's the rear main the oil pan also which in a 2wd means pulling the engine.
I'd thoroughly clean the engine first to be sure it isn't one of the upper things running down. They're all easy by comparison. Hard to tell in the pic because that area is pretty oily and dirty.They're all easy by comparison.
I also can't figure out why the oil filter appears to be on the passengers side next to the transmission cooling lines.

If it is the real main seal and you do not want to replace it you could try switching to a high mileage oil which has seal conditioners in it. Also there is a product called AT-205 Reseal which many have good luck with, you can look into that product and it's reviews and decide for yourself.
That's not the oil filter. It's one of those little plastic plug like things that are in the bellhousing. I think they were for the machine that carried the engine/trans around before putting them in the trucks.I also can't figure out why the oil filter appears to be on the passengers side next to the transmission cooling lines.
That plug provides access to the oil pan bolts hiding under there.That's not the oil filter. It's one of those little plastic plug like things that are in the bellhousing. I think they were for the machine that carried the engine/trans around before putting them in the trucks.
Good to know... I have yet to remove any of those from any of my trucks, and all 3 have them.That plug provides access to the oil pan bolts hiding under there.
