Resistance Forces Other Than Aero

Tri-Flow works great on chains. Light lube smells sorta like bananas

Transmission can be treated, REM process current, in the past used SuperTech treatment.
If nothing else, you can narrow up the gears (within reason) or groove them to reduce the pumping action.
Ceramic bearings can reduce drag also. Be carefull of application, I have destroyed full compliment units due to shifting (engine speed accel/decel).

This may not be useful to anyone here, but link-plate-chains (aka "silent" chains) have a surprising attribute- they inherently display near-zero internal friction! The Morse website has a very clear illustration of how the design (using Morse Hy-Vo as an example) utilizes a "rolling" action rather than the pivoting action of a roller chain. I don't know, however, how typical chain-to-sprocket friction values compare with roller chain.
[Anybody remember the monster-sized engine-to-transmission link chain of the FWD Olds Toronado?!]

We had those trannies in the GMC motorhomes
