Aisin AS69RC

Aisin AS69RC Transmission Specs & Ratios

The Aisin AS69RC is a medium duty 6 speed automatic transmission offered in the Ram 3500 HD beginning the 2013 model year. It is similar in design to the AS68RC, which was only available in chassis cab Rams mated to the 6.7L Cummins. The AS69RC is one of three transmissions offered beginning the 2013 model year, and comes standard on the High Output version of the 6.7L Cummins only available in 3500 pickups. The transmission is larger and more robust than both the AS68RC and 68RFE.

Ram claims the transmission has a 64% higher input torque capacity than the 68RFE. It is manufactured by Aisin Seiki, a Japanese automotive parts supplier. Though actual input torque capacity is unknown, its application suggests it is in the 850-950 lb-ft range. The AS69RC also replaced the AS68RC in chassis cab models for 2013. Its wide ratio spread provides low gearing for tow applications, while a relatively high 0.63 second overdrive keeps engine rpm low at highway speeds to maximize fuel economy. The AS69RC was replaced in Ram chassis cab 4500/5500 truck models by the Aisin AS66RC beginning the 2014 model year.
