There's a small cover plate on the bottom of the bell housing. I think it's held on by six 9mm bolts. It has to cime off, or the flywheel won't clear. This little cover plate has frustrated many an owner. ;)

I know the diesel has that forsaken plate. He has a 2.3, so it likely has some sort of plate there. Can't say for sure

If you have removed the plate, provided there is one, and it still won't come loose, ON MY DIESEL, I've take a bottle jack at the rear of the transmission mount, a block of wood between engine head and firewall to hold the engine, amd jack up pressure on transmission to open up a gap.
I've pulled 1 gas engine and didn't have that much trouble getting them apart

The plate is on the bottom front of the bell housing. It is about 1.5-2 inches tall, and maybe 6-8 inches wide. If you don't remember taking it off, that's most likely your problem.

Thanks for the info. I should have clarified that my truck is a 94 model. Mine doesn’t have that plate. How do I go about posting pics here?

Brad,

If it's the MSG5 (2wd) transmission and a 2.3 engine, it should have the plate -- If it doesn't, you can see the flywheel from underneath the engine. I've pulled a few of these in salvage yards, I I know they have the plate.

If it's the MUA5-T (4wd), I don't know if it has the plate.

To post pictures, they need to be on the computer or phone you're posting with. You have to be in "Full Editor" mode (not "Quick reply"). Scroll down to the attachments section and add files (photos).

My guess is the pilot bushing hanging up on the trans input shaft? I'd say everything is unbolted, otherwise I don't think you'd have gotten it as far apart as you have. I think I'd get a buddy to help and try prying with 2 or 3 pry bars at one time, spaced equally. Try to keep the input shaft and crankshaft in line so it pulls straight off, not cocked to one side or the other. With the combo sitting on the floor, it may very well be in a twist or bind. I wouldn't go caveman, either, as I'd be afraid I'd break the bellhousing or block. hth

I agree. You don't want to break off any chuncks of bellhousing casting either.

Here's a thought: Did the clutch work normally before the teardown? I'm thinking that a failed release bearing has friction-welded itself to either the pressure plate fingers, or to the release lever. The upper picture shows just about what the throw-distance of the release lever would be. If so, how to get that critter outta there is another story. Can the pressure plate bolts be accessed, etc...regards!
