Muncie 4 Speed
 

I have a Freshly rebuild Muncie 4 speed and I was wondering what It would be worth....

Sorry about the post in this forum but I wasnt sure where to put it

Thanks

M20, M21 or M22
Big difference in sale price.

I just had an M-20 gone through. The original trans cost $500 (was supposed to be good!) After 3 new gears, slider and rebuild parts, it cost me $800.
So I have $1300 in mine. Not sure you could get by much cheaper. Most so called rebuilts are selling between $1000 and $1600.
Way to much considering you can buy a new 5 speed around $2000.

Not much difference between an M20 and M21 in price, but an M22 will be quite a bit higher.

M21's are hard to sell unless its for a resto job. The M20 will work better with more highway friendly axles like 3.73s 3.42s and 3.31; and the M20 shares the same 1st, 2nd, 3rd gears and reverse geartrain. The difference is in the cluster and input (maindrive) of the 20/21.

The M22 does NOT have spur gears, however the only common gears it shares with the 20/21 family is the mainshaft reverse gear and the splined idler gear. All the other gears are M22 specific

Things buyers want to know:
Input Splines / Output Splines?
damage to case?
new wear parts?
7/8" or 1" countershaft?
Gear Ratios?
Whats it work best with?

If I had a non-numbers matching M21; I would rebuild it as an M20 because it fits a wider range of cars and its probably easier to sell

M-20 M-21
1st 2.52 2.20
2nd 1.88 1.64
3rd 1.46 1.28
4th direct direct

Put trans in 1st and turn output 10 revs, count input revs to determine ratio.

Aside from the ultra numbers-matching lunatic fringe; Id say 800 and up to probably 1200. If it was freshly rebuilt with a warranty; you could get 1800 depending on options

And NO 26 spline input/ 32 spline output is NOT an M22
the spline change from 10/27 was YEAR specific, not MODEL specific

where would i find the numbers on the tranny to find out what it would be?

Hope this helps.

Sorry to hijack...but in the old days the story was you could tell an M22 (w/o pulling the side cover) by the big drain plug on the right side. Then I heard that all over the counter 4 spd. cases had the drain plug.....which is true. By the way I was building a 355" sbc for my 240Z back in '79 and bought a REAL M22 from a guy for $50, he had wrecked his 70 1/2 Z-28 and was hurting for $$$$. I sold it the next week for $450....BIG money back then.

I know. About 10 years ago I bought a 71 Z-28 that ran into the back of another car at low speed and wrinkled a fender and broke the grill. It had about 60K miles and I bought the whole car for $1,000 and put the running gear in a 39 Ford coupe.
These things are way over rated and over priced these days.
I had a T-10 in a 56 years ago and it was fine. Very strong, I really believe just as good as a Muncie and you can still pick them up fairly cheap.
I guess the days of picking up old 4 speeds for $100-$150 are gone... along with $.32 gas and $.25 Cokes!!!!
I think I like the old days better....
