i know im goin for royal purple, but im unsure of what to use, i plan to change it every 20k, and but cost isnt an issue, ive seen some use Max-Gear, Max-ATF, and then Synchromax

i dunno which to use and how hard is it to change the fluid on those puppys????

 

I am using the royal purple atf right now. no problems so far I will put sycromax in it next time. I visited thier web site after buying. they recomend either. I run the sycromax in my 2 stroke atv gearbox with no problems also. i have the 75w90 front annd rear. 1 plug drains the transfer case the other fills it. Word of advice make sure the fill plug comes out first then pull the drain plug.

 

what color is the sycromax? and you think 20 to 30 k changes are good?

 

it's all purple. And yes 20-30k is just fine. Now this is assuming you do not have the auto trac that takes a special blue fluid from GM. It is a must with auto trac.

 

Is the dealer the only place I can get Auto Trac fluid ?

 

oh crap ya mine does have auto trac so do i need to go get it from the dealer?

 

Yes I would "strongly " suggest the auto trac "blue" synthetic GM fluid. I know of no other place to find it other than dealer. I have heard it's around $6 a quart(don't quote me)

 

i've just used ATF fluid (dexron III) just like i did in the Tranny

 

oh ok as long if its not some like 25 dollars a bottle lol then im fine, uhhh can you use that auto trac in ur transmission?

 

No it doesn't work in the tranny.
