Pretty much every guide and instructional video I've seen says to use a prying tool to push the transmission back. I don't know how I would get it off without prying.


I am supporting the front of the engine with a floor jack. I've tried numerous small adjustments of the angle by lowering and raising the jack slightly.

I got them a little farther apart. I took this picture showing the shaft completely out of the clutch disc. It's currently in a little farther than this (engaged but probably just barely) after various attempts to remove it.


Once the shaft and clutch disc are separated the only things that should still be in contact are the two studs in the bottom, right? The two alignment pins are completely out. The studs don't seem like they're binding. I can push the transmission around up down left right and it moves freely through a small range of motion. It will move slightly back and return slightly forward when I let go. When I try to push it backwards with a pry bar on the bottom, the back of the transmission just tilts up until it hits the underside of the car.



It seems like either something isn't lined up exactly perfectly (I don't know how perfect it needs to be), and maybe once it's aligned to within a microradian it will come off. Or maybe the pilot bearing came out of the flywheel and it's stuck on the transmission shaft?? That seems unlikely.

Sounds stupid, but has the wiring of the gearbox dropped?

Have you disconnected the drive shaft?

Good catch...looks to me like all the starter wiring has not been taken loose...if the splines are that far out, it's not binding there...is the shifter disconnected? Drive shaft? all wiring?

I finally got it out last night! I'll post more details when I get home from work this evening. Short version... The bracket that the transmission is pinned to at the top near the shifter was stuck hard and wouldn't budge even with the pins removed. It required major persuasion to dislodge, but once I did I had the transmission out within a few minutes.

Oh yeah... that bracket got in my way too. We'd disconnected it fine but it got pinned between the body and the trans and was preventing us from sliding the trans out fully. It was pretty much impossible to see too, only noticed it by feeling around.
