Is it possible to bolt a 5-speed MTX III or MTX IV tranny from a tempo/topaz onto a 3.8 v6? The only thing I can think of that wouldn't work would be the flywheel and clutch, since the 3.8's never came in a front-drive layout with a 5-speed. But then, would a flywheel and clutch from a RWD 3.8, like out of a t-bird, work with a FWD trans? Everything else should theoretically work, with maybe a bit of cutting and bashing to fit. I don't even care which car the engine/tranny is in, tempo/topaz or taurus or even an escort (that'd be fun actually, a 3.8 v6 escort GT
Hold me back!
), I'm mostly concerned with whether the engine and tranny will mate up at this point. Thoughts, advice, anything? Much appreciated

There's been many discussion about using the SHO MTX, but I don't remember if there was a final verdict about that. A Tempo/Topaz tranny will bolt upto a Vulcan. You would also need a way to get the computer to think there's a manual transaxle in the car.

Anything could work with a lot of time, money, and patience.

Yes, it will bolt up. It was the mounting that had me stumped, however, and where to source a flywheel.

I've since dropped the project, and sold the MTX IV I had, since my new car will come with a 5 speed.

Aha!! So it WILL bolt up! I figured as much, but it sounds like you had the same problem with the flywheel, I can't find one anywhere that will work!! I was hoping that a flywheel from a rear-drive car would work, but there's no way to find out short of buying a flywheel & clutch and trying it. Maybe a vulcan flywheel will bolt up to the 3.8? I don't see how, since they're totally different engines, but it's worth a shot. How about drilling new bolt holes and/or enlarging the pilot diameter on a vulcan flywheel? I'm thinkin' that'd mess up the balance, it might shake itself apart. This is kinda starting to bug me
Anybody else with some info?

I don't know, but if the Vulcan and Essex uses the same tranny, wouldn't the flywheel be the same? I don't think the RWD flywheel would bolt up. There's a minor difference between the FWD and RWD Essex motors.

Ok don't quote me on this but I THINK the 1st or 2nd Gen MTX SHO flywheel will fit.
I've been mulling over something similar with my car for a long time if you will remember only thing is my car now is fried. b**** fried her piston rings.
Which REALLY bums me out and ticks me off. Oh yeah for those who remember me telling you about my car check the west coast chapter forum I have current pics of her up in there, she looks pretty sweet.

SHO MTX flywheel will definitely not fit, nor is it balanced correctly.
