Hi Everyone,

Many late model Toyota Transmissions have a sticker that contains the Transmission Compensation Code. This Code is suppose to be programmed to the ECM when a replacement Transmission is installed.

Does anyone know if this Compensation Code can be found anywhere else on the Transmission?

Is it something Toyota could provide, if they were given a Serial Number from the Transmission, like Nissan does on some units?

Thanks
