Removing MTX

Post by nerox » Tue Feb 12, 2013 3:45 am

I'm trying to remove the transmission bit something is amiss.

The engine is removed from the car, I've undone all of the big bolts around the edge and now the trans casing is free to spin by hand around the shaft but I just can't separate it from the engine.

Someone help me please??

Did you remove the 4 bolts holding the flex plate to the clutch assy?

Hmmmm .... I'm guessing not, where might I locate those?

On the front bottom of the bell housing, there should be an inspection plate, probably a 10mm head screw holding it in place still. where the oil pan to MTX brace is/was. Remove that, and turn the engine via the damper bolt to bring the flex plate bolts around. Then have a helper hold the crank end while you remove the bolts at the flex plate.

Did you remove the dust shield that's held on with one 8 or 10mm bolt on the bottom of the trans? I've done the same thing but it bolts to the trans and sits behind the clutch. Won't let it come off. You should be able to remove the trans while leaving the clutch in place.

So many neons so little time.

Truth. I guess I was thinking more of the shaft binding in the clutch disc that morning. :)

This is why I couldn't get my transmission off. :beatstick:

I guess I always remove the flex plate bolts, so the TC/modular clutch come out with the transaxle, so not taking the inspection cover off didn't occur to me.

You have to slide the mod. clutch onto the input shaft for easier re assembly anyways, so I just do the step of taking it off the engine while I am separating the two.

I guess since the clutch is modular, I treat it just like if it was an ATX.

Finally managed to remove it by taking off those bolts :)

On a side note ... isn't that the flywheel you called a flex plate?

The flex plate is what transfers power from the crank to the modular clutch. The flywheel is the cast iron part the pressure plate is riveted to.

hmmm .... so the 4 bolts I removed, held the flex plate to the clutch, which is modular and therefore includes a flywheel all in one piece ?

so if you install the tranny with the clutch inside it how do you line up the clutch assembly with the... flywheel? whatever the fuck that round plate with the ring gear for starter is called since it only bolts on one way?

I normally do a rear main seal while I have it apart, so the flex plate is off the engine to do a rear main. I lay the plate onto the flywheel, and turn it until all four holes line up, them use some bright spray paint on the small hole that nothing goes into. It is in about the same circumference plane as the bolt holes in the flywheel.

Then once the MTX is mated to the engine, I just turn the clutch assy until I see the paint mark through the hole, and thread the bolts in.

You can also do the paint before you take it apart...

A felt marker may work, but they tend to fade, and are hard to see. A Paint marker would be a better option if you have one handy.

Edit: They carried that damn bolt pattern from the 1972 up A, B, RB externally balanced cast crank V8's. The TC's had weights welded on, so you had to have it clocked correctly, or the engine would be out of balance. IIRC, the forged cranks and TC's prior to the cast cranks did not have the asymmetric bolt pattern.

Yes the flywheel, disc, and pressure plate are all one assy.

I noticed Tuesday my '01 does not have the small hole I mentioned. I just put two of the holes in the inspection area, and turned it until they were lined up, hand threaded two bolts, and turned the other two into the window.

You got at least a 50/50 chance that way. Still beats the risk of bending the clutch disk, if things go bad getting the MTX to line up.
