DTT 4.4 LEVER

The 4.4 ratio apply lever applies 2nd gear. 2nd gear in the 47RE is a band that wraps around the front drum. This drum is spinning in first gear and when the band applies and stops this drum, you are now in 2nd gear.

There is a piston (servo) that fills with hydraulic fluid to apply the band. The 4.4 ratio apply lever is in between the piston and the band itself. It acts like a pry bar. It causes a mechanical advantage. Placing one pound of force on the tip of the apply lever causes 4.4 pounds of force on the band.

The factory apply lever from '94-'02 had a 3.8 ratio. Using the 4.4 ratio gives us 15% more torque capacity in second gear than the stock set-up at equal pressures.
