overdrive Transmission software
Did you know that your H&S tuning device also has the capability of tuning your transmission? If
your 5.9L Cummins is equipped with the 48RFE automatic transmission, you may want to check
out our Overdrive Transmission Software. Custom tailored to mate with H&S engine tuning,
the 5.9L Overdrive software includes modified torque converter lock/unlock strategies that will
command the TC to lock in 3rd gear under wide open throttle and hold it locked through 4th gear.
Light throttle torque converter strategies have also been changed to lock-up sooner, keeping more
power directed to the road instead of wasted in heat and friction. Shift points are modified to
take advantage of the available horsepower and torque output. On a 2006 Cummins with a stock
48RFE, we have seen 0.2 to 0.3 second quicker 1/4 mile times JUST from the addition of the H&S
Overdrive tuning! An additional unlock fee may apply, see www.hsperformance.com for details.
