Transfer case lube

[cyclejerk]

A local shop tried to sell me some transfer case fluid. I do not think it was the correct type so I opted out.

 

Is this fluid blue? red? What weight ?????

Here's what the Auto Trak II Fluid bottle looks like.

If auto, the common wisdom is to only use the blue GM Autotrac fluid ... This is my maintenance list:

 

Trans service: 5qt M1 ATF

Rear axle: 3qt M1 75w90

Front axle: 2qt M1 75w90

Transfer Case: 2qt AutoTrak II Blue GM: 12378508

If you want a better product, look into the Syn's. Royal Purple or AMS oil I believe makes products for the transfer case.

AMSOIL does not make a direct replacement for the AutoTac II. For now just use the GM Auto Trac II. It isn't that expensive and it is only 2qts.

I got mine from Partszoneonline.com otherwise known as P&G CHevy. It was only like $4 something a quart. I got 3 Quarts but it only takes two. I did buy the replacement bolts with the dope (Teflon Tape) on them. I hope this helps. Also, make sure you take the fill bolt out first. You want to make sure you can put back in before you take out.
