What's it worth

Hi Howard,
It is indeed an over the counter transmission denoted by the CT9 stamping which translates to a 69 model year assembled unit. If the gearset is original to it 3950316 is an M21 close ratio and it was assembled on Sept 6, 1968 which also explains the lack of the model i.d. letter that shows up later on 69 muncies. If the gearset internally is in good usable condition, $750 is in the ballpark.

If it helps, I just sold an M-21 Muncie about 5 months ago for $900. It had been gone through, new seals, etc. but gears, etc. were all original. I listed it on Craigslist for $1,000. Had about 15 people contact me about it. First person that came and looked at it bought it.

Chis,

Isn't , C = Chevrolet , T = transmission, 9 = Model Year?

Where would the Model of Vehicle be designated?
