The Clark is a five speed. If the nomenclature only had a letter, it's a non overdrive. An O after the letter indicates overdrive. For the other larger truck transmissions, I'm not sure how they denote it in their nomenclature.

I was lucky as this is the transmission that was behind my 478. My truck is also a 4 X 4, but it has a divorced transfer case so it is only a simple matter of fabricating a shaft between the transmission and transfer case.
