WTT - My rebuilt never used m20 tranny for your m21
 

I have an m20 tranny that I had rebuilt several years ago as an extra. Never used it and never had oil in it.

Looking to trade it for an m21, has to be in good usable condition. nothing that needs rebuilding.

Or if someone is interested in purchasing my m20 I will do that also.

Looking to get $850.00 obo best offer. Prefer pickup as shipping would be an issue.

Pics and other info upon request.

Thanks,
Mark

What year is your m21 and is it out of a pontiac.

I have an m20, I am looking for an m21.

I do not know what the m20 is from, I purchased as a spare and had it rebuilt. I will look up the numbers on the case if I can figure out how to decode them.

Thanks,

a little late....couple yrs...
I have a 100% ready to run M21 looking for similar M20?...

I would trade two fresh rebuilt M21s for one Auto Gear M23 with the 2.99 first gear. I will even throw in a fresh Hurst shifter for one.
One M21 has a reproduction case.

Sorry guys, at this point I am looking to sell my 4 speed tranny's. I have a new one coming and do not need my m20 or super t-10 anymore. No trades.

Thanks,
Mark
