Hot Shot’s Secret introduced an addition to their Blue Diamond Severe Duty Transmission Fluid family. Now joining their Multi-Vehicle ATF and Ford Type F & Allison C4 is an all new formula – Blue Diamond G56 6-Speed Manual Transmission Fluid, formulated to resolve problems associated with the Mercedes-Benz built G56 6-speed manual transmissions, which are commonly found in newer Dodge Ram trucks. Blue Diamond G56, while developed specifically for G56 manual transmissions, meets the specifications for any application where a SAE 50 manual transmission fluid is needed, including any demanding street, towing, or heavy duty application.
Hot Shot’s Secret Blue Diamond G56 transmission fluid resolves many of the issues that have plagued the G56 6-speed manual transmission, such as rough shifting, excessive rollover noise and vibration, and high operating temperatures. The G56 manual transmission is commonly found in 2005-2018 Dodge Ram trucks and various Mercedes-Benz vehicles. While Mopar ATF+4 fluid is commonly used as the transmission fluid for these vehicles, it was not specifically developed for the G56 transmission.
Hot Shot’s Secret’s formula was developed specifically for the G56 transmission and is based on 100 percent poly-a-olefin (PAO) Group IV and high-quality Group V synthetic oils and is infused with FR3 Nano Technology, an extreme pressure additive package and special friction modifiers. This allows for improved shifting, lower operating temperatures, and improved wear protection, the company says. Blue Diamond G56 also provides increased oxidation resistance, thermal stability, and protects against deposit and sludge build-up.
“We were approached by a few customers at the races that had complaints of noise and difficulty in shifting with their G56 manual transmissions,” said Aaron Darnell, R&D technical director, Hot Shot’s Secret. “The issues seem to intensify with an aftermarket flywheel, clutch, and increased power. We knew we could develop a high-quality fluid that would solve these customers’ G56 issues, we just needed to nail down the formula. We formulated a few different versions and sent them out for third-party lab testing. Once we determined which formula performed best in the lab in terms of wear protection, oxidation resistance, et cetera, we were ready to move to real-world testing.”
“Since it is hard to test noise and shifting issues in the lab, we needed real-world testing,” said Darnell. “We reached out to a driver who had asked a question about using our FR3 Friction Reducer in his G56 transmission on our website, since he was experiencing hotter transmission temperatures and noise, and he agreed to test the new lab formula on his Dodge Ram truck. He reported a reduction in temperature by 20 to 25 degrees Fahrenheit, quieter operation, and smoother shifts and synchro engagement with the fluid swap. We then ran multiple real-world tests with people who opted in to trying our new formula. With good feedback, we settled on the formula and began preparation to bring it to market.”
