Stick Shifts use ATF too, but its only used to cool the transmission vs doing the actual moving of the vehicle. </div></BLOCKQUOTE>
Actually New Process Standard Transmissions since the late sixties have been totally filled with ATF in the gear box in many applications not just in an auxiallary cooler. That includes some of the D100 pickups (I owned a 72), the 1971 Plymouth Duster Twister Demon (one of mine also) and the Chrysler front wheel drives of the 80's both the 4 speed manuals an the 5 speed manuals (I still have an 85 with the 5 speed). It gives better fuel economy and provide easier cold weather shifting.
My 69 Power Wagon had gear lube in the tranny but that was a W200 E20 special order 4 wheel drive pickup truck with a 3 ton payload, limited slip front, posi rear, full locking transfer case, 440 under the hood, 4000+ lb 12 inch clutch and 4.78 gearing among many other items out of the norm. No quite what you would consider run of the mill.
Believe me I did a double take when I saw this for the first time almost 40 years ago but yes here was a brand new standard transmission car with ATF as the factory fill in the gear box as specified in the owners manual. I have not checked out the specs on the newer ones however I would see no reason for them to discontinue what has worked so well over the past 40 years especially with gas prices going the way they have. </div></BLOCKQUOTE>
The fluid, to my knowledge still gets moved through the cooling system, the basics of transmissions book I own is a little vague in that area as it predominately pertains to automatics, so there's a good chance I'm wrong, but it would make sense to cool the fluid that's absorbing the heat from the internal friction.
