Just wondering why more people have not switched over to ATF in the front diffs. I have been using it in all my Polaris machines since the first day I bought a 4 wheel drive. Never had one minutes problem out of any of them and my current rides have 10000 miles on one and a little over 8000 on the other.

The 2002 Magnum Polaris shop manual on page 7.9 states to use PPDD or Type F ATF in the front hubs. Since Type F is for pre mid/late 1970's Ford automatic transmissions requiring high friction modifiers I could see how most any ATF might work to make the electro-lock up feature work OK. If concerned one could just pick up a quart of Type F ATF to be on the safe side. Really could not see how a synthetic ATF could be of much added value unless the front hubs are getting up to 250F degrees. :)

Front and Rear gear case calls for GL5 80-90 per same Polaris shop manual on page 2.6.

Polaris does not offer a transmission grease cross reference that I can find in the shop manual but New Venture manual transmissions use Syncromesh??? found in some GM and Chrysler vehicles that seems more like 5W-30 Motor Oil and since I have some I may try that in the transmission since it is a proven light weight transmission lube and I have a bottle. :)

The synchromesh fluid should work fine if you don't have a chain in the gearbox... I'm not sure about the Magnum... my Sportsman does so I'll stay away from that..

Chaincase lubes are an odd duck. They are lighter oils with anti-foaming additives more on par with ATF than gearcase lubes... but they have the smelly EP addpack like gear oil.

I've used Amsoil chaincase lube in my 92 Indy 440 for 13 years l. I have some on hand so I'll prolly use it in my Sportsman transmission for my fall change. The sled was done this spring.

The front diff is the only place I'll keep using the Polaris stuff. For now...

That is what I have always used in my 700 and sleds.
