U140E Pump 1999, used and ready to install. Fits the U140E. Ships fast from the USA.
For the 1999 model year, Wikipedia's application list puts the U140E four-speed transaxle in just two vehicles: the Lexus ES 300 and the front-wheel-drive Lexus RX 300. If yours sits a beat too long before Drive or Reverse takes hold, slips in more than one gear once it is warm, or makes a whine that climbs with engine speed while parked, the front pump deserves a hard look. This is a used OEM U140E pump listed for 1999 applications. The photo shows the pump body with its stator support shaft in place, so you are swapping a complete assembly instead of reusing a scored housing.
The U140E is an Aisin-built transaxle, and on these early Lexus models one computer runs both the engine and the transmission. That computer can only command shifts; the pump is what actually moves the oil. It is driven by the torque converter hub, so it turns whenever the V6 is running, and its output is regulated into line pressure that feeds the four valve-body solenoids (SL1, SL2, S4 and DSL), every clutch and brake, the converter and the lube circuit. Engagement into Drive depends on the C1 clutch filling quickly, with the C1 accumulator cushioning the apply. A pump that has lost volume fills C1 slowly, which is why a lazy Neutral-to-Drive engagement is usually the first thing an owner notices.
Several U140E faults imitate a weak pump, so rule them out first. Sonnax points out that a 2-3 flare or late Reverse usually comes from direct clutch sealing rings wearing into their grooves (they spec .003-.005 in. ring-to-land clearance), from a missing washer seal between the case and rear cover, or from damaged B2 seals between the valve body and case. Those faults hit one range. A tired pump drags everything down together. Check the fluid level hot, then put a gauge on the line pressure tap and compare Drive and Reverse at idle and at stall. Low everywhere points to supply; low in one range points to a leak in that circuit. Our line pressure testing guide shows the hookup, and Aisin slipping under load helps you tell pump loss from worn frictions.
This pump is listed for the 1999 U140E. That points to the ES 300 and the two-wheel-drive RX 300. All-wheel-drive RX 300s use the U140F, and Sonnax splits the 1999-2005 valve bodies in this family into front-drive and all-wheel-drive versions, so do not assume parts cross between the two. Read the transaxle code on the case tag, then compare the stator shaft splines, bolt pattern and O-ring grooves with your old pump. If you are unsure, send us the year and VIN and we will check before it ships. For later Camry, RAV4 and Highlander applications, a new U140E/U240E oil pump covers the wider range, and the rest of our U-series parts sit in the hard parts category.

Probably not without checking. AWD RX 300s use the U140F rather than the U140E, and the family has front-drive and AWD part splits. Compare your old pump or send us the VIN and we will confirm.
Wikipedia's application list starts the U140E in the V6 Camry in 2002, so a 1999 Camry most likely has a different transaxle. Check the code on the transaxle tag before you order.
At minimum a front seal and pump O-ring. If the fluid is burnt or line pressure was low for a long time, plan on clutches, seals and rings from an overhaul kit, plus a new filter and pan gasket.
Yes. Reset the learned adapts with a Toyota-capable scan tool, warm the transaxle up and drive at light, steady throttle through all shifts until they feel normal.
It is a used OEM pump, listed with a 1-year warranty, and it ships from the USA.
