Assuming that what you have is a three speed trans with side shift levers there is no real reason that it wouldn't work. That is also assuming that it is from a 53 and later chevy. You will need to find a three speed shifter and cut up the floor board to accept the shifter. Ibelieve the 53 bellhousing is the right one to use as it should be drilled for the bellhousing side mounts that the 37 car uses. You will have to do a little trimming on the rear cross member to clear the 235 oil pan and maybe also the front cross member to clear the vibration dampener.
In my opinoin a better trans to use is the T5 five speed from S10 V6 pickup or a camaro. If you use the pickup trans the shifter is in a better location. If you use the camaro trans the low gear ratio is more usable. Or the best of both is use a camaro trans and swap out an S10 tail housing to it which gets the shifter farther forward. The 5 speed will keep the engine in its good usable torque and rpm range at highway cruzin speed.
I run this combo in a 37 sedan with 3.73 rear end , p225-75-15 tires. 65MPH= 2200 rpm and 21 mpg
Good luck with your swap. Gael
