2004 2005 2006 Lexus LS430 4.3L 6 Speed Automatic Transmission JDM 3UZ-FE A760E

Vehicle Fitment

This transmission serves as a direct replacement for the following North American models:

• Lexus LS430: 2004, 2005, 2006

• Compatibility Note: This is the 6-speed automatic. It will not fit the 2001–2003 LS430 models (which use the 5-speed A650E). Please verify that your shifter has the "S" mode (sequential shift) gate before ordering.

JDM to USDM Installation & Technical Guide

To maintain the "sealed-unit" precision and OBDII compliance of your Lexus, professional technicians recommend these critical steps:

• Internal Harness & Solenoids: You must transfer your original USDM Transmission Internal Wire Harness and Solenoids to the JDM unit. While the mechanical gears are identical, the electrical plugs on JDM Celsior units often vary. Reusing your original USDM electronics ensures the ECU receives the correct data and prevents "Check Engine" lights or limp mode.

• Neutral Safety Switch: Transfer your original USDM Neutral Safety Switch (Range Sensor). This ensures your dashboard gear indicator and the starting safety circuit function perfectly.

• The "Sealed" Fluid Procedure: This transmission does not have a dipstick. It is mandatory to use Toyota ATF World Standard (WS) fluid. After installation, the fluid level must be set using the "overflow plug" method at a specific temperature ($95°F - 113°F$) to ensure shift quality.

• Transmission Cooler Flush: Debris from a failed A761E can hide in the lines. Flush the transmission cooler lines and radiator thoroughly to prevent contaminating your "new" JDM unit.

• ECU Reset: We highly recommend a Transmission Adaptive Memory Reset via a professional scan tool to allow the ECU to learn the fresh clutch tolerances of the JDM unit.
