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.
Key Performance Differentiators When Using Idemitsu ATF
Precisely engineered formulas match OEM friction materials and exact viscosity requirements, providing “dialed-in” performance.
Excellent anti-shudder durability, oxidation stability and deposit control
Smoother shifting and higher torque capacity for high-energy clutch engagements
Precise friction enables increased utilization and controlled slipping of torque converter lockup clutch for improved fuel economy
Reduced warranty claims and repair call-backs
Automatic Transmission Fluids (ATF)
The Case Against Generic Multi-Vehicle ATF
Multi-vehicle ATF was introduced to simplify inventory for service shops by reducing the number of fluids needed. However, as OEM transmission fluid specifications have become more differentiated, a few ATF products can no longer meet the diverse requirements of most vehicles. While multi-vehicle ATFs still hold a significant market share, their applications are increasingly limited. These formulations often compromise performance and longevity, leading to friction properties that may not align with OEM standards. Over time, this can result in reduced efficiency, clutch plate glazing, excess heat generation, accelerated wear, and ultimately, shorter transmission life. Idemitsu addresses these issues by producing custom ATF and CVTF formulations that meet original OEM standards, ensuring reliable performance.
Multi-vehicle ATFs were designed to reduce fluid variety for service shops.
OEM specifications limit the effectiveness of multi-vehicle ATFs.
Compromised formulations can lead to reduced performance and longevity.
Poor friction properties can cause efficiency loss and increased wear.
