Transmission codes on Framingham Build Sheets for 69 Chevelle

[SS69chevelle]

These are the codes I have for that box from different build sheets in my records. I will check some of the Framingham ones and see if they have anything different.

XC- M20
XG- M20
XD- M21
XF- M21
X1 or XI - M22


take care Andy

Checked several of the build sheets and portions and they seem to only use the codes below for the four speeds. the other codes may be used but I do not have any examples of them.

XC- M20 L48, L35
XG- M20 L35
XF- M21 L78
XI - M22 L78

take care, Andy

My car is a Framingham car with a build sheet, original engine (L78) XD in box 29, bench seat. Clearly a manual from new but I don't know if it could had been a three speed? The shifter is a Hurst not a Muncie, and the gauge carrier is for a manual car. The column is not from a column shift car. The tunnel has torch marks like on a Camaro for a 4 speed, but, I don't know if Chevelles had the same torch marks on the hump like Camaros did or not?
Any other XD codes in box 29 on Framingham build sheets?
