Why you don't want the Allison AT545 Transmission in the mountains.

Does your bus have air brakes?

I dont have one yet. Going to look at one later today or tom.(87 international 1753 i believe, 6 window, so im thinking no air brakes) Im assuming its an auto, so AT545. It sounds like i can make it work. Just gotta be slow and do it right. And they are cheap.

Really, that dude having one in a tow truck towing RV's up grade gives me faith. Much less getting 185k out of it.
