Merchant Automotive Performance Transfer Case Fluid | 2 Qt

Merchant Automotive Performance Transfer Case Fluid is blended specifically for GM transfer cases. It's an upgrade over the factory fluid that improves shifting, reduces wear and quiets driveline clunk and clutch chatter. A typical GM HD transfer case takes 2 quarts, so it comes in a 2-quart bottle that fills the case once with no waste. It works in manual and electric shift transfer cases, gas or diesel, and is a cost-effective upgrade for transfer cases that call for ATF or Auto-Trak II.
