According to recent industry analysis from Market Research Future, the global electric oil pump market is on a significant growth trajectory. The transition from hydraulic to electrified auxiliary systems has elevated the electric oil pump from a niche component to a pivotal enabler of modern vehicle architectures . In transmission applications, this technology is fundamentally changing how lubrication, cooling, and actuation are managed.
Electric oil pumps (EOPs) are mainly used in all types of transmissions—including automatic transmissions (AT), dual-clutch transmissions (DCT), continuously variable transmissions (CVT), and dedicated hybrid transmissions (DHT)—for lubrication and cooling of gears, clutches, and eDrive components . They are also used for hydraulic actuation functions such as clutch engagement, gear shifting, and hydraulic park-lock systems . Valeo, a key supplier, notes that their multiple flow electrical oil pumps are "particularly adapted for pure oil cooling and lubrication of electrified transmission (BEV Hybrids) and/or hydraulic actuations" .
The strategic importance of EOPs in transmission systems lies in their decoupling from engine speed. A traditional mechanical oil pump's flow is tied to engine or wheel speed, which can lead to over-supply of oil at high speeds (causing churning losses) and under-supply at critical low-speed, high-load moments . An electric pump, however, provides precise, on-demand flow, allowing engineers to "right-size flow" for the specific thermal and lubrication needs of the moment . This controllability is especially critical in start-stop systems and EVs, where the engine-driven pump is not active.
The market for automotive electric oil pumps was valued at USD 1.99 billion in 2025 and is projected to reach USD 2.90 billion by 2032, growing at a CAGR of 5.54% . The transmission application is a primary driver of this growth as automakers seek to improve efficiency and reliability in increasingly complex drivetrains. The electric oil pump market continues to evolve with innovations that make transmission systems more efficient and reliable.
