I just went out to the truck and crawled all under it. as it turns out, without the engine running, it still drips. Probably just due to head pressure. A steady drip.
The curious part is that it appears to be coming out of the rubber plug at the bottom of the bell housing. I pulled the plug out and sure enough, I see drips falling off the bottom tooth of the ring gear.
Are there freeze plugs under the bell housing?
It's a 4X4. How much of a job it it to pull the tranny out and replace it if there are plugs in there?
I have had a number of two wheel drive trannys out, all manual. Looks like a really big job. I have an adapter for a transmission to go on my floor jack.
And what benefit would I gain from replacing the tourque converter to eliminate shudder while I'm in there.
This may all be premature at this time.
