Description

The All4Swap ATEMU is an Automatic Transmission Emulator designed for UZ/JZ equipped Toyota/Lexus vehicles since 1998. It simulates critical features of specific automatic transmissions, allowing the use of a factory ECU with a non-original transmission. This prevents the ECU from entering limp home mode, thus avoiding significant power and torque loss.

The ATEMU replicates essential functions to ensure optimal engine performance. For off-road applications, it retains non-critical error codes to simplify installation and reduce costs. An included resistor pack can be wired in to eliminate the Check Engine Light (CEL) if needed for street legal applications and emission testing.
