My mom's 1982 Corvette has a transmission with 9YA054N stamped on it which seems to be the typical model for this car. It seems to be having some issues and I have a 1FUM067C that is available to put in if its doable. I believe that it came out of a 1991 Firebird. I would have to change out the tail section but other than that, will the swap work or are there too many internal differences?

Change the tailhousing, and speedo gears.....everything else will work fine. You'll also be putting in a better trans, with a larger input shaft, and better pump. I assume you have the torque converter for the '91 trans too, because the one for the '82 will NOT work.

I do have the torque converter form the 91 but not really sure how good of shape that its in. This may be the time to just get a new one and not take any chances.
