Deuce M35A3 questions

[SteelNinja]

The M35A3 with an Allison Trans . Did they all have lock up converters? My neighbor says he runs Plain hydralic fluid in his ( automatic 5 tons) and has done so for years. Your thoughts?
also does the M35A3 and a 5 ton have the same trans? If not will they interchange? Im really leaning towards an A3 a friends dad has available.
Thanks -appreciate any info...

No, they dont lock up

No, they are not interchangeable

The M35A3 uses the Allison AT1545 series transmission. It came with a "lock-up" torque converter. The standard AT540 series never had a lock-up torque converter. As far as the differences between the 2.5 ton and 5 ton trucks transmissions goes. The 2.5 ton (M35A3 Deuce) used the AT1545 transmission rated up to 36,000 Ib vehicles. The 5 ton (M939) used the MT640/MT650 series transmission rated up to 73,000 Ib vehicles, and a input torque of 640 ft Ibs.

Just out of curiosity, would you mind telling me how much he wants for it? I'm kicking around the idea of one but don't know what they go for.

Sorry I mean the truck.
