Tremec T5 
This transmission requires just under 3-Quarts of oil. We recommend that the fluid in a TREMEC T5 transmission should be changed after its initial 1000-2000 miles. The fluid should be inspected between 30,000 and 50,000 miles after that. For severe driving or racing, fluid changes should be made frequently, especially when operating temperatures of the transmission fluid exceed 250°F, inspect accordingly.
