With the drivetrain finished and filled with fluid, Miller adjusted the TV cable with the "rule of thumb" technique. Basically, with the engine off and the throttle held wide open, you tighten the TV cable until there's no slack. A quick testdrive will ensure the TV is in the ballpark. If the transmission stack shifts, meaning rapidly shifts through the gears to Third or Fourth, the cable needs to be tightened. Stack shifting means not enough line pressure, and the tranny will burn up. With our TV cable adjusted, we fine-tuned the vacuum-actuated lockup switch mounted on the side of the tranny. Now, at 75 mph, our Jeep cruises at 2,500 rpm with 4.56 gears and 32-inch tires.
