Ford Triton V-10 Info Request
The question I asked the other day helped me and as much as I am liking the idea of Workhorse chassis with the 8.1 Chevy and the Allison, I found out that not all 8.1 drive trains have the Allison tr...

The transmissions (and engines) varied by year but not really by chassis rating. The axle might be different--I'm not sure on that. In general, the Ford transmissions are pretty solid and reliable if not overly abused.
There are three main transmission variants you might find: the four speed 4R100, the five speed 5R110, and the six speed of the last few years (the designation of which I don't know offhand--6Rxxx I suspect). The five speed can be differentiated from the four speed by the button on the end of the shift lever: on the four speed, it's for "overdrive off" and labeled as such, while for the five speed it's "tow/haul." Overdrive off, on the four speed, does exactly what it says; it's like shifting from overdrive to drive on vehicles that have those two settings for the transmission. Tow/haul, on the other hand, doesn't lock out any gears, but instead alters the shift points and timing and such to better work with heavy loads, including automatic downshifting for engine braking on downhills. I think it's a good thing to leave engaged all the time assuming you have it.
In terms of the V10 engine, there is one main upgrade (the two valve to three valve head, with a significant increase in torque and power) as well as various more minor improvements over time. The three valve version was introduced in 2005, it appears.
