Thanks to all, again.
Yes, I had heard some techs say not to change fluid on old transmissions, but their reaons were vague, at best.
I have always thought that fresh fluids would never hurt, but wanted to check it out with you all.
I will be changing ALL fluids, including trans, rear end, and brake. I'll leave the old air in the tires, though!
Thanks again for all the replies!

A friend who is a cross-country bicyclist once told me that he changes the air in his tires before every trip. He says it rides better with new air!

I have also heard that racing bicyclists use "dry" air to fill their tires. The idea being that the compressed air has little or no humidity, no condensation inside the tubes/tires and thus less weight

Also the tires on commercial aircraft are filled with nitrogen-- probably for the same reason.

And remember that some shock absorbers are filled with pressurized nitrogen. There's something about the properties of nitrogen.

nitrogen gas in tires

hi all

my dad who drove trucks when there was chain drive rear ends, wood spoke wheels and solid rubber tires and who i thought had a handle on anything in the big trucking equipment use to tell of a story about trucks using nitrogen in the tires specially in the deserts of the west coast because the nitrogen gas did not heat up like normal air does. a cooler tire runs for a longer life.

kinda made sense to me so if the air line jets use nitrogen just think about the landings we've all seen for years on tv and what not. they can really smoke them up on landing so that would create heat.

so it does lend some credibility to my father's story about truck tires and heat.

just my .02$ worth
Thanks Much!
