Ames was only 1 of about 10 posts with ATF.

There are gears in an automatic transmission too...

sure... it works great, high detergent too so its not all nasty later on. It has more then enough protection, 4wd drive trucks use this in transmissions and transfer cases, all the new stick cars use it too, and gear to gear puts it thru alot more stress then chain and gear does. it rolls better cause its thinner but provides great protection, and the cost of it is even better!
Been using it for over 15 years, have yet to have a bearing or chain failure.

That's quite a range, from ATF to 75/90 wt gear oil.

well if it is good for automatic trans...in all types of weather/all kinds of conditions..how could you go wrong using it.

ATF is fairly corrosive, and can also eat up rubber seals fairly nicely if they aren't designed for it. Comparing a snowmobile chain case to an auto trans isn't apples/apples, unless they have the same parts and seals.
Don't know if anyone has had seals fail because of it, but its certainly not impossible.
The other thing to consider is that ATF is hygroscopic. (absorbs water, even just moisture in the air) snowmobile chain cases run obviously much colder than a car transmission, and you never get it warm enough to get rid of that moisture.

always run ATF here too. Never any problems.
I use Amsoil Series 2000 chaincase lube. I'm sure there are a lot of different lubes that will work, but this stuff is designed for - wait for it - chaincases! IMO gear oil is way too thick for this application.

Try atf in a manual 5 speed that was made for 90w gear oil it does not last to long. i know because its been done to me.
The some of the newer manual trans are designed to run on aft, thy have every different bearings
I would somewhat disagree with alot of your statements. We have rebuilt many automatic transmissions as well as manual transmissions. In most automatic's the internal materials are not much differant than a snowmobile chain case. ie the aluminum is no differant as well as some of the bearings and seals. As for manual transmissions which run atf, they are no diffeant either. As a general rule of thumb but not complete, a cast iron transmission run gear oil and an aluminum transmission runs atf. Most current transfercases run atf, these are aluminum. Most older cast iron transfercases run gear oil. The exceptions are those which run a multilink chain, similar to a snowmobile chain but much larger in design, these run atf or 10w oil. Gear oil is too heavy to properly lube our chain cases in extreamly cold conditions. Chain case oil is the primary oil to use, secondary would be 10w or ATF. Happy trails Alsmokingcrater said:

as of right now my sleds got 75w-90 synthetic . love the idea of using atf though. be damn easy to tell where its coming from if ya get a leak! gonna do my kids sled this weekend, probably go with tranny fluid.

IMO - comparing a snowmobile chain case to an aluminum t-case mated to an auto trans is a pretty close apples to apples comparision.
I've used Mobil-1 10w30 in manual transmissions (for improved cold drive away shifting) and in my chaincase and would recommend it and/or trans fluid.
To each his own.

I very clearly stated new transmissions, not 1965 trans missions, if you dont want to use atf, no problem dont use it. I have yet to have a single failure and i save alot of $$ over the gimmick chaincase lube at the dealer..........so use what you like!

...and not just truck transmissions as mentioned earlier.
Interestingly enough, the 2013 5.8L Shelby Mustang uses Mercon V and the 3.7/5.0 uses full synthetic m/t lube.
700 H.P. (with trac key) at the flywheel vs. 120ish into the chaincase.
Many here have enough time on thier trans fluid filled chaincases to suggest it works... and works well.
FWIW - I still use a 75w90 gear lube in the cast-iron 833 NP four speed in my 'Cuda.

I hate to suggest something that is radical and unusual but you could follow Yamaha's instructions.
Do what the Yamaha engineers want done. They know what is best. They have been studying and testing drive systems and lubricants for thousands of hours.
Just follow what they say and forget about everything else.
Read your owners manual. Do what it says.

you guys don't want to hear from me.. I'll PEE on your cornflakes !!!bluemonster1 said:where is Gary Nosboy on this one..been waiting for his comments...
Also REMEMBER,, they're interested in SELLING NEW SNOWMOBILES TOO !!! If a better lubricant,, that will last longer IS AVAILABLE,, they HAVE TO CONSIDER if it's WORTH their investment to add that lubricant OR to specify a lubricant that will SUFFICE just to get out of the warranty period.... There is a LOT OF TRUTH to that statement....PZ 1 said:
