You should find a Turbo-Hydramatic metal tag riveted to the passenger side of tranny case...this will have a two letter code, eg: CW, CX, CY...and so on. There were also be a julian date and model year date...refer to this SYC thread for photos and info:

This will help identify what kind of tranny you have...the last 6 of the VIN will also be on the case (edge of bell housing or near the shift arm on drivers side)...if the VIN matches the car...this will help to confirm original driveline setup...those 2 letter codes have specific engine/model applications...if you have the info or a photo of the tag post it and we will help you decipher.
