your manual tranny is going to be an np435, great tranny's.

first i must ask why you want to swap tranny's?

next, yes your auto tranny will swap in but you are gonna need alot of extra parts for the conversion

Welcome to the Site. Does your radiator have tranny cooling line fittings? You will need those, as well as the cooling lines. You will need the kickdown linkage. This is a must; you'll burn up that tranny without it. There was some difference in the way the crankshaft was drilled, so you will hafta take care of that, but I can't remember off the top of my head what is required. The cross-member might be different, as well as the speedo cable. All in all, it wouldn't be that hard to do.

I actually prefer my automatic. I like it cause it has some give on ice, not like a manual where you gotta slip the clutch for an easy start. Same with pulling a load. However, I don't think an auto belongs in an 18-wheeler.

well i am putting a manual valve body in it and why do you guys think i shouldnt swap
I'll admit that the 727 is a great transmission, but it's an automatic. To make it perform you'd have to install a manual valve body simply to mimic what you already have with the 4 speed.

I'd keep the manual, unless you have physical limitations that prevent you from driving with one.
