I am trying to mate my transmission back to my motor and cannot get it to fully seat. The transmission is getting held up about a quarter inch. I also cannot pull it off again to check to see if something looks wrong.

Also if I spin my front pulley the transmission wobbles so I don't know if that means I have the clutch on crooked or something.

Any advise?

 

Use long bolts and washers

 

Are you trying to mate them on or off the car?

Did you service the clutch? If so, did you use a clutch alignment tool?

To separate them, make sure they're both fully supported and use a BFS (Big F'n Screwdriver) to pry the bellhousing from the engine.

 

So are you saying to just put the bolts in and start tightening them and that will mate the transmission?

I am mating them out of the car on an engine stand. I have the rear of the engine facing up and placing the transmission onto the engine.

Yes I serviced the clutch and yes I used an alignment tool so I don't think it would be off center.

 

Using big bolts is the 'brute force' method of getting this done which can cause transmission input shaft damage, idle bearing or seal damage, and generally is unnecessary.

The method you described of installing the transmission input shaft to the clutch/flywheel, everything should drop right into place easily and then just a matter of tightening bolts to spec. I would suspect that either the rubber grease seal for the input shaft idle bearing has gotten crammed into the idle bearing, or the clutch is out of alignment with the flywheel and friction surfaces. Take a close look and run your alignment tool back in there and try again. Those are about the only things that could get in the way during transmission bell housing install. Good luck,

 

since the whole thing is out of the car, you might wanna pull it apart and see if you can see anything obvious.

if it was in the car, i would use a few bolts and gradually walk it together. you don't want to tighten one and make it crooked, you want to try to keep it as even as you can

 

Nope it wont damage anything if you tightened the bolts a little bit at a time and evenly. Its a common practice. If fact, when installing new clutch, i always use brake cleaner to remove any paint off the spline or dirt and then slide it several times in the trannys input shaft to ensure it doesnt bind and slides freely

 

thanks got it.

 

I've had much better success mating the transmission to the engine while the transmission is still installed. Lowering the engine into the bay typically catches the input shaft nicely and the whole thing just slides together.

 

Both engine and tranny must have the same angle. Flywheel side titled down and up for tranny. Once theyre lined up, lower the hoist for the two major parts to kiss each other and work on the tranny to engine bolts.
