Automatic Transmission Fluids (ATF)
The Case For Vehicle-Specific ATF
New transmission designs require specialized lubrication to address unique needs, especially as the number of gears increases for greater efficiency. Smaller clutch packs and reduced surface area of clutch plates demand Automatic Transmission Fluids (ATFs) that balance frictional properties for optimal performance. This includes providing the right coefficient of friction for proper heat transfer and wear protection while ensuring compatibility with torque converter lockup clutches to prevent issues like shudder. Achieving this balance relies on advanced friction modifier additive chemistry and engineered lubricant technology.
Increased gears lead to higher efficiency in transmissions.
Smaller clutch packs and reduced clutch plate surfaces require precise ATF properties.
Controlled friction is crucial for torque converter lockup clutches to avoid shudder.
A robust combination of additives ensures smooth vehicle launches and shifting.
Idemitsu engineers solutions tailored to meet specific OEM lubrication requirements.
