Sporty acceleration is no longer the sole domain of those who like to shift gears; Dinan Automatic Transmission Software welcomes you to the performance zone. In order to take full advantage of the higher rev-limit provided by Dinan Engine Software, the transmission software raises the shift points to a higher rpm, allowing you to carry more road speed in each gear. In addition, vehicles equipped with shorter final drive gearing are then able to achieve at least 60 mph in second gear with the higher shift points for optimum 0-60 performance. Dinan Transmission Software may only be installed in conjunction with the matching Performance Engine Software as there is no benefit without the higher rev-limit.
- Faster shifts for improved acceleration (part throttle & wide-open).
- Raised wide-open-throttle shift points to better utilize increased rev-limit in Dinan engine software.
- When in manual mode, transmission will not upshift if kickdown switch is not engaged (i.e., “true” manual mode at any throttle position less than WOT).
