Automatic Transmission Emulator

The All4Swap ATEMU (Automatic Transmission Emulator) is an innovative device engineered to seamlessly integrate non-original transmissions with factory ECUs in UZ/JZ equipped Toyota and Lexus vehicles manufactured since 1998. It meticulously simulates the critical functions of specific automatic transmissions, such as those found in 1UZ, 3UZ, and 2JZ applications. By replicating essential transmission behaviors, the ATEMU prevents the factory ECU from defaulting to limp home mode. This is crucial for engine swaps or modifications where a different transmission is used, as it avoids the substantial power and torque reduction that would otherwise occur. The device ensures your engine can achieve its rated power output, maintaining optimal performance. Designed with installation simplicity in mind, the ATEMU also retains non-critical error codes. This feature is particularly beneficial for off-road applications, streamlining the setup process and lowering costs. For those requiring street legality and emission compliance, these error codes can be addressed with the addition of compatible components. Additionally, a resistor pack is included to help eliminate the Check Engine Light (CEL). The ATEMU offers flexibility for various engine swaps and modifications, working compatibly with factory ECUs and a range of transmission setups. It is manufactured by All4Swap® and has compact dimensions of 44x32x9 mm with a weight of only 28g. The product comes with a lifetime warranty under specified conditions and is available for worldwide delivery.
