The best operation of this transmission is achieved by setting your engine idle speed below 1400 rpm. The shift pattern is the standard P R N D L configuration. The motor should be started in the park position only.

This valve body will not allow the motor to idle in low or drive. To engage the transmission in forward place the shifter in neutral and depress the clutch pedal until the car is moving forward (similar to a Bert or Brinn) then quickly move the shifter to low. As the car picks up speed move the shifter to drive which will lock the transmission in direct drive. You may move the shifter to low gear for slow speed operation. If you must stop the car then you must place the shifter in neutral.

To engage the transmission in reverse simply place the shifter in the reverse position and increase the engine speed. Also be sure engine speed is at a minimum before shifting into reverse as the reverse clutches are the weakest component of any powerglide transmission.

The valve body is equipped with standard carburetor jet to bypass the fluid in reverse. The reverse jet (located on the bottom of the valve body) is a Holly #90. This jet may be increased in size if the car tends to stall when stopped in reverse, although larger jets may cause excessive slippage and premature wear on the reverse clutches. It is wise to adjust your idle speed as low as possible before you make any changes to the jet. If you do change the jet be sure and check main line pressure to be sure it is 70 psi or above with the transmission in reverse.

The fluid capacity is 3 quarts with out an external cooler. A cooler is not required for short races (25 laps or less). If the transmission is to be used on longer races a cooler should be used. A good quality ATF (F type or synthetic) should be used.
