Not sure how we missed this, hope you have your question answered already. If not, the car I drove everyday with the ECU for over 2 years was an 06 G35 A/T. Ran great...no hiccups. No options for the trans, but the stock ECU did a fine job with the car. The 128 has the ability for TC through the CAN bus. Feel free and call the office if you have any further questions.
