Im in need of a good F5M21 trans. Must be good shifting and not need a rebuild. I live in Northwest Indiana ,30 minutes from Chicago. Contact me 219-308-2790 my name is Rob.

Or a f5m31 trans as I have been told will work.

F5m31 will require another trans mount to work properly.

Stepped mounting bracket.

Edit ==== The F5M31 is the KM210, which needs a turbo colt mount or other (not sure what else had this and was compatible).

Yes, 89Mirageman is correct as this puts you into the territory for a larger flywheel and clutch setup.

Good news is, most people swap out stock type of stuff and sometimes before punishing the car because they know a torquey turbo setup won't be compatible

any longer.

Good price point when that comes about, stock flywheel and clutch.

Also, the starter is different between the F5M21 *4g15 motors* and the 4g6X motors.

So, best to find a decent F5M21 trans IMHO.

Doesn't the F5M31 have the larger bell housing for a stepped flywheel too?

I can deal with the mount. Just want to make sure I can use my clutch,flywheel and axles.

So does anybody have a good F5M21 trans? This shouldn't be so hard to find.

I just looked up starter for my 92 mirage and a 92 eclipse and they are the same part number.

Have a read through here, food for thought. Starter may work, you would be the first to post that I can remember, unless something was posted years ago. Site goes back to 2003, might or might not be listed here.

Be sure the axle spline lengths that go int the trans are the same.
