[BBIGG BLOCK 396]

One indication of a transmission being a M22 is it will have no rings around the input shaft.M22 trans came with the course and fine splins input shafts.All M22 cases will have been drilled and tapped for the drain boss.Sometimes you will also see different type spline output shafts on a real M22 trans.But the tale tale sign is to pull the side cover and look at the cut of angle on the gears and that will determine in fact if it is a M22.I have some literature on 4 speeds and will try to get a moderator to post this where everyone can go to it and refer to it when needed.I will have to dig it out of a box.Also the rings or grooves around an input shaft actually designate the gear ratio of the trans.I do not remember all the trans cases #'s to quote them but do have that information.I will get it out and make it availiable to all.I actually dealt in muncie shifters and transmissions for awhile and compiled some information on the trancsmissions.A lot of people see a Borg Warner Super T10 and they think they have found a M22 but Borg warner did not make a M22.Although the Super T10 Borg Warner trans was a great trans to use for a high performance operation.
