: : : I have a 1949 DPW I have repowered with a 1967 304 IHC V8. I used the stock transmission
: : : but it is non-synchro and all the seals are shot. What was this 540 transmission used in? Is the 5th gear
: : : an overdrive? Does it have a PTO to run my winch? Please help.

: : Yes, my 540 transmission is an overdrive version. The New Process 540, 541, and 542 5 speed transmissions seem like the best choice for overdrive in a Power Wagon. They came in large trucks, Dodge, Chevy and probably others, typically a dump truck or something. Most were direct drive but can be changed to overdirve by swapping gears. I believe they are shorter than the current NP 4500, which probably is too long without moving the PW transfer case back.
: What engine are you using in front of this transmission? Do you know, would a transmisson like this have the correct left side PTO for my winch and PTO? Also, how can I identify a transmission like this?
: When I repowered my truck, I had the same radiator problem that you are having and to solve it I switched to a radiator out of a 1951 1 ton IHC. It had the opposite outlets from stock and seems to work just fine. I haven't run it enough to know if overheating will be a problem with heavy loads.
: I did have to get a new filler neck soldered onto the top tank.

Can you tell me which trans. have overdrive in the fifth gear? What vehicles were they (overdrive trans.)used in ? How can the direct drive fifth gear trans. be converted to overdrive? ie. Are the gear sets available? Where can I find them? Thanks for any info!!!
