A540E

The 4-speed automatic transmission А540E produced by Aisin Warner has been used since 1989 on AWD and FWD 2- 3 liter Toyota Camry, RAV4, Sienna and Lexus ES250 and ES300. In terms of design, this transmission is the part of А140 - А240 series with interchangeable parts, but it can transmit a higher torque. There are several sub-modifications of this transmission.

The most significant design changes were introduced in 1994 for А541E used with 3-liter engines, this gearbox differs in friction components of the 2-brake package andadditional 4-th solenoid of the torque converter lockup in the valve body. Tested design, simple electrical components and most importantly control settings that made it impossible to load components of this transmission to maximum torques – all these conditions ensured high reliability parameters of the A541 unit and durability of this transmission.
