Aisin Warner 09G Electronics: Anatomy of shift controls
There has been much focus over the years on valve-body wear issues and other deficiencies of the 09G as well as the TF80/TF81 models. Once a repair had been made, shift or apply issues still existed at times, requiring more attention to the controls.
The experts at Rostra Precision Controls have devoted a substantial amount of effort to determine how all the aspects of Aisin six-speed transmissions (valve body, solenoids and TCM) work together to provide a well-functioning and durable transmission repair.
