The Overdrive in Operation

 Take your Ghost for a test drive after double checking wiring and lubrication.  Before activating the overdrive, drive your car for a few miles to check for any vibration in the driveline and to insure initial component lubrication in the overdrive.

 If you installed the control box, turn on the master power switch (Photo 18).  With your Ghost traveling at least 20 miles per hour, the green light on the master switch should illuminate providing visual indication that the overdrive can be activated.  (Never reverse the car if the green light is illuminated to avoid damaging the overdrive.)

 Engage the overdrive by depressing the clutch and activating the overdrive’s solenoid through the manual switch (Photo 19).  In addition to extending your top end cruising speed, the overdrive can be used as a “split-gear system,” providing a half-step between existing gears.  For example, you may have encountered terrain where engine RPMs were too low in fourth gear and too high in third gear. The overdrive allows you to split the gears with an overdrive in third gear, providing a half step between third and fourth gears. The same would apply in top gear by downshifting from overdrive (at the flip of a switch) into fourth gear. (See Table 1 that illustrates intermediate shift points for an overdrive mated to a 14/52 rear axle).
