RatioTek has announced a new transmission tuner kit for the AS69RC transmission, a six-speed automatic transmission that was made for Dodge by the Japanese gearbox manufacturer Aisin Seiki.
The kit fits 2013 and later 3500/4500/5500 Ram trucks. According to the company, the kit recalibrates clutch solenoids for increased clutch oil apply pressures. It installs from the bottom without removing transmission, RatioTek noted.
