Synthetic D6 Automatic Transmission Fluid is suitable for use in the new Dexron® VI applications, Mercon® SP, or Toyota WS fluids are recommended. The D6 Automatic Transmission Fluid is a lower viscosity version of the D4Automatic Transmission Fluid and is designed for better fuel efficiency in CAFE testing. Dexron® VI requires a different approach to conventional Automatic Transmission Fluid formulation. Rather than beginning with a 7.5 Centistokes fluid and allowing a viscosity loss in use to drop to 5.5 Centistokes, the Dexron® VI fluid requires a starting viscosity of less than 6.4 and a final drop to no less than 5.5 Centistokes. Red Line D6 will drop to no less than 6.1 Centistokes. Since the final viscosity after use of these fluids are similar, Dexron® VI fluids can be used where Dexron® III fluids were previously recommended. The D6 Automatic Transmission Fluid also provides significantly improved gear protection and will provide a GL4 level of gear protection, making it a superior product for transmissions and transaxles. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum Automatic Transmission Fluids allows high temperature operation without varnishing valves and clutches which leads to transmission failure.

Bought this for my son. This is the second suit from this company that I've purchased and the quality is great. The material isn't cheap. My boy looked very nice and he received a lot of compliments.

Prom Suit
Color: Blue, Size: Medium
It came fast but the pants was still kind of big on my son he’s in a small for everything and I fix the jacket because the arms was a little bit long but my son loved it and said it was comfortable. Maybe size down if you can.
