Lots of good info in this subject. I'm assuming same would apply for my 55 passenger OD trany? This is a unit I picked up, will need to check it out, hopefully it's not just another door stop.
Yes, it's for the most part, the same transmission as what was used under the trucks. The only main difference, depending on year of the truck and what engine it has, will be the side cover and shift levers/forks.
