This specialized lubricant is engineered for use in vehicle transmissions that combine the transmission and differential into a single unit. Commonly found in front-wheel-drive and some rear-engine vehicles, it plays a crucial role in ensuring smooth gear changes and efficient power transfer. As an example, a vehicle with a transverse engine configuration often employs this fluid type.
The correct fluid type is vital for optimal performance and longevity of the combined transmission and differential system. It provides lubrication to reduce friction and wear on internal components, dissipates heat generated during operation, and protects against corrosion. Historically, the development of such fluid types has progressed alongside advancements in transaxle design, with formulations becoming increasingly sophisticated to meet the demands of modern vehicles.
