Suncoast Full Synthetic Transmission Fluid

SKU# SC-TYPE-D ATF

Features and benifits include:
  • - Outstanding low temperature performance and sheer resistance

  • - Dramatic improvements in thermal stability during endurance environments

  • - Optimized frictional properties that can provide smoother shifting during low temperature operation, reducing shudder and vibration

  • - Outstanding resistance against sludge and deposit formation

  • - Improved anti-wear protection, which directly contributes to extended transmission life

  • - Unsurpassed low temperature stability

  • - Resists foaming and thereby promotes outstanding operability


Throughout the years, SunCoast has put enormous effort into the research and development of failure prevention in some of the most extreme environments that exist today. These environments are not limited to hot shot driving, sled pulling, drag racing, and the Texas Mile. 

Suncoast Full Synthetic Transmission Fluid

For our own success and growth, it has been imperative that oil analysis be our measuring stick for improvements. We can use this to determine the amount of degradation that transpires during a drive cycle. This is key when we are determining what friction coefficients work best in a particular application. This process has evolved with both the friction material and fluid types.

  As technology has evolved, so has transmission fluid. Here at SunCoast, we have been on the leading edge of this development. We have seen the evolution from the original Dexron that was introduced back in the late 60's, that utilized sperm whale oil as a friction modifier; to the early 70's when Jojoba oil was introduced, along with corrosion inhibitors, making it hygroscopic. Fast forward to today and the evolution continues.

  SunCoast has known for quite some time that we have more success with certain fluids than others. There is a science to the madness, and we knew it was in our best interest to ensure we understood this. In 2006, when General Motors released Dexron VI it set a new standard within the industry. Through our independent testing, we were able to verify that this was an improvement over anything we had seen to date. This is when SunCoast made the decision that this was an area we should definitely become more familiar with, knowing this is how we are protecting our units. Since 2006, SunCoast has spent countless hours reviewing data from oil samples that we have sent in for testing, in an attempt to figure out what works best for our environments.

  Today, we are proud to present you with the fruits of our culmination of analysis and research, Suncoast Type-D Full Synthetic transmission fluid. This new full synthetic transmission fluid contains all of the prescribed combination additives that improve the lubricating qualities for your high stress transmission. The specialized additives include anti-wear, rust and corrosion inhibitors, detergents, dispersants, and surfactants (surfactants protect and clean metal surfaces). In addition, we have also added very specific viscosity modifiers, seal and swell additives, and anti-foam additives. This fluid has yielded us the best test results to date and offers uncompromised performance. We are also proud of the fact that this fluid is full synthetic, not a blended fluid as so many others have attempted to pass off. The SunCoast Type-D Full Synthetic transmission fluid also has a slightly lower viscosity at lower temperatures than the competitors¬ź fluid, decreasing parasitic drag during normal driving conditions. This, of course, requires the use of higher-quality, more sheer stable base oil compounds when manufacturing. Rest assured, with this new full synthetic fluid you are getting the absolute best protection on the market today.
