Brand New U660E Transmission Oil Pump Housing Cover OE3503573012 for Lexus ES350 RX350 Toyota Camry 3.5L U660E 6AT Gearbox

This is U660E automatic transmission front oil pump housing cover assembly, OE NO.3503573012, pre-assembled with original matching rubber oil seal, specially for Toyota/Lexus U660E 6-speed automatic transmission.

Different from integral pump body, this part is the front pump end cover with built-in sealing ring; its core function is to seal front input shaft and fix pump gear set. Aging seal or deformed housing will lead to front housing ATF leakage, insufficient main pressure, gear slipping, delayed shifting and gearbox overheat. Our finished pre-sealed cover directly replaces damaged original parts.
