M35A3 Manual Swap from Cat 3126 w/ 6spd?

you won't like the 5t 5 speed because of the HOLE between 3 & 4

Excuse my ignorance, but just what do you plan to do with the truck that the auto trans can't handle it? The super singles and power steering are enough to sway me away from the a2 or older.

I like a manual trans. I don't think the auto is not functional, I just think I would enjoy the truck more with a manual. I also suspect the proper manual trans would yield a better, and more acceptable, top speed. I guess that is just a personal preference issue.

It seems like there is no good answer. Maybe I am not the first to come to this conclusion.

pretty much an Eaton/FSO is the best option, or use a 5T Spicer 5 spd.[/QUOTE]

What is an FSO? Is the ZF6 in Ford applications?

FSO is an Eaton/Fuller trans; S=single countershaft, O=overdrive (if non-OD, then it will just be an 'FS' trans). then the numbers are like 5065, 6085, 70-something and on...

the first number is the number of gears; 5, 6, or 7. the next three numbers are the torque input rating; ex: 085 = 850ft-lb. lastly, there could be a letter after which would designate the gear ratio group if there were options.

so an FSO6085A is an OD 6spd, rated for 850ft-lbs, with gear ratio package 'A'. same nomenclature scheme that Eaton/Fuller uses for the rest of their trans lineup.


yes, the ZF6 was mostly used behind the Ferds diesels ('99-'10) but was also used behind the D-max for a while, can't remember the years right now.

but the ZF6 is big...
