Transmission Swap Adapter Kit for IS300 to 350Z/370Z 6-Speed

The MMS FAB transmission swap kit provides a streamlined method for installing Nissan 350Z (CD001-CD009) or 370Z (JK40 series) 6-speed manual transmissions into a Lexus IS300. This kit is compatible with 1JZ-GTE, 2JZ-GTE (both VVTi and non-VVTi), and 2JZ-GE (VVTi) engines. Included in the package are a J1, J2, or J3 adapter plate, input shaft seal, a complete bolt kit, and a pilot bearing. To complete this swap, users must supply an Aisin A340 automatic transmission J1 or J2 bellhousing, along with the corresponding bellhousing bolts. Additional required components include an IS300 manual clutch pedal assembly and an IS300 manual master cylinder (a Toyota Celica GTS master cylinder is also compatible). To prevent check engine lights and ensure the vehicle can pass emissions, it is recommended to utilize a transmission simulator to replicate the stock automatic transmission pump speed and solenoid resistance.
