1969 M22 & 1973 M21 Muncie Transmissions
 

1969 M22 rockcrusher transmission with original GM gears and has been gone through with new bearings and synchronizers. The transmission has the correct #660 case, #584 tail and #306 sidecover. I don't see any stampings on the transmission $2500.

1973 M21 transmission with all original GM gears and has been gone through with new bearings and synchronizers. The transmission has the correct #661 case, #648 sidecover and #648 tailshaft. The tranny is stamped 13K574866 P3E05B $1000.

Can ship if you cannot pick up and can send pictures as well. Any questions I can be reached at 330-770-2517.

The 73 trans has a strange vin and the B at the end of P3E05B is a M21.

transmission..
 

The VIN looks like a 68 unit for a Chevelle...:hmmm: maybe the "8" is a "3"..??

the stamping looks like a 1973 date with M21 letter code..

1973 M21 was only available in Corvette, Chevelle and Camaro..

the letter code designation began in the fall of 68 for the 69 model year...

so...perhaps a closer look at the numbers to clarify the 73

Here's my 73 Z28 M21 for comparison if you need it. I can delete it if you don't want to see it in your thread.

Yes I hit the wrong keys when putting the add up. It came out of a 1973 chevelle and is a M21 transmission. I do have pictures of it if anyone wants to see them.
