Merchant Automotive Performance Transfer Case Fluid is our recommended fluid for all GM transfer cases that call for ATF or Auto Trak II. One typical GM HD Transfer Case will use 2 Quarts, so we conveniently offer Performance Transfer Case Fluid in 2 quart bottles for a single fill with no waste.


Features & Benefits

  • Promotes proper transfer case performance
  • Enhances shifting performance
  • Dramatically reduces wear
  • Improves component efficiencies
  • Blended specifically for use in GM transfer cases
  • May be used in GM, Ford and Chrysler transfer cases
  • For use in diesel or gas transfer cases
  • Cost effective upgrade for Auto Track II
  • Suitable for both manual and electric shift applications 
  • Reduces irritating drive shaft clunk
  • Increases drive line performance by reducing clutch chatter within the transfer case
  • Drastically reduces wear on internal components & seals


Merchant Automotive does not recommend overfilling a transfer case. Please fill your transfer case to the factory recommended fill level which in the case of most GM HD truck applications is 2 quarts. We recommend changing the transfer case fluid about every 2-years or 50,000 miles whichever comes first.


My transfer case was dry or way less than 2 quarts of fluid came out when I drained it. My output shaft seals look good and show no signs of leaking, what could be the problem?

With a 1998 through early-2007 transfer case, pump rub is the likely problem.

Developed for ALL GM transfer cases that call for ATF or Auto Trak II for the fluid fill. May also be used in Chrysler, Dodge, Ram and Ford transfer cases.

Great video, Eric. I had not heard of using engine oil before and never would have considered it. However, the info about ATF was new knowledge for me. I know I’ve been running the MA fluid ever since you put it in my 05 Allison years ago and besides just trusting you, now I know why. That’s probably why I’m about to trip 300,000 hard pulling miles with no problems. I enjoy your videos and usually learn something from every one. Even if it’s something like alternate uses of an engine stand to bell housing adapter. Keep them coming.
