I’ve got a Muncie M20 that I’m looking to part with. I don’t know much about these transmissions and I’ve seen them for sale anywhere from $500-$2000. Any guesses on how much I should list it for? Thanks for the help

To be honest it is probably worth $400.00 to $600.00. Its a 50 year old transmission and its not installed in a car so there is no way to judge how it performs. Even a fairly fresh professionally rebuilt M20 isnt worth $2K.

Local CL has a guy with a rack full $650, I'm sure there's M-20's in the bunch, I just clicked his add 64 M-20 $650, others are well over $1,000, 70 M-20 sold for $750 not rebuilt, Orlando CL

No offense but that M20 is rough. Looking at your pictures, it looks like the one ear is cracked and there looks to be some welding.

Please verify.

Your buyer will probably be planning to rebuild it (who would be willing to run a 50 year old transmission as-is without going through it?). With that in mind, it would help to get good pictures of each of the 4 mounting ears to show that they aren't cracked. Remove the side cover and take a picture of the internal gears too. The condition of the mounting ears on the case and the condition of the gears inside are the two most important things that a buyer will want to know. As long as these two things check out, list it for $750 and see what happens.

In addition to the above, 63-65 cases seem to go a lot cheaper, anything 7/8 shaft. 400 range or less.

That is an 010 case, which is 1966-67 only. The tail housing is 429, which is 63/early-65 ------------------------------ UNLESS it came out of a Pontiac (such as a GTO). Pont used the 429 tail housing up to 1970.
The side cover bolts have been removed, indicating someone has at the bare minimum, looked inside. What is inside?
Since 5-6spds with OD have become so common, the market for a Muncie is soft (I'm still a BIG Muncie lover), thus, the value for a Muncie is very low-----------------------ESPECIALLY for a core in unknown condition. Also, for ANY 66-67 Chevy, it is not correct because of the 429 tail housing (speedo fitting on left side), which could easily be changed to a 584 tail housing (speedo fitting on right side). If any gears or syncros are needed, I personally would not walk across the street to give $150
Sorry, I know that is what you wanted to hear-----------------------but you asked. Muncies were never painted black, and for someone that wants a nice looking Muncie, it may be a challenge to get all that black paint off.
Yep, I see a lot of labor there!

I sold my rebuilt M21 with 1" countershaft. $750. sold on the first day, pretty sure I priced it too low.

 

[Shane 69 Hugger]

I would think there's $500 there...maybe $600

Was it professionally rebuilt with receipts to show so and relatively low miles since rebuild? If yes then you may have been a little low.
If not then you got a fair/good price.
Not picking on you but a rebuild without proof should be considered just a story.
Same thing as buying an engine or maybe just an engine block and asking if the block has been cleaned and crack checked.

The muncie I had in my car had stripped out holes leaked at the counter shaft and really needed to be rebuilt. I got $300 for it.

 

[Richard/SIA]

$300 core, no more.
Proper rebuild runs around $1200 and I have receipts to prove it.
Since you can get New five speeds at only $2K a Muncie really only makes sense if you have a serious reason to run it.
They do take less space and are original to a lot of older cars.

a few years ago I listed a M20 for 400 and a M21 for 500 on craigslist. Add said just the trans (shifter was attached) I got 1 call for the m21, guy was interested in it at 500 only if I included the competetion plus shifter. I ended up keeping both trans and shifters for a future project. jim

 

[Jim Mac]

I was going to add, of the used muncies I've installed, 70 chevelle m20, 71 nova m21, 66 chevelle m20 all worked like they should without any other work. jim

$1200 was what I was quoted to rebuild the muncie transmission I sold for $300. I bought a brand new Auto Gear M22W for $2k.

Well they are actually closer to $3K and if one has been running a Muncie then they will need a few other items such as clutch, yoke, driveshaft altered. However I agree it doesn’t make much sense to put $1K-$2K into a fifty year old Muncie when the 5/6 speeds can give you something the Muncie can’t, which is the overdrive.
