STEP #1:

Transmission should be cool before installing. Be sure vehicle is secure to prevent rolling.
Drain oil by carefully removing transmission pan bolts. Recommend leaving a couple of bolts
partially attached until some of the oil has drained.

STEP #2:

Remove transmission filter. If 1968 or newer model, remove retaining bolt, hold pipe that filter
is connected to and then pull filter off.

STEP #3:

Before loosening valve body, note how the gear selector lever connects to the manual control
valve in the valve body. Fig. #2.

STEP #4:

Remove bolts from valve body and then carefully remove governor tubes and valve body
together. Avoid bending governor tubes. If 1970 or newer model, disconnect white wire

from the valve body. Also, be sure the manual control valve doesn’t slide out.

Note: Sometimes the Intermediate Servo will fall out when removing the valve body, Fig. #3.

STEP #5:

Remove the two bolts holding the downshift solenoid and valve body spacer plate. Make sure
you support the spacer plate with your hand. Lower the plate with steel balls carefully.

STEP #6:

If transmission is being overhauled when installing the valve body, the following steps will
enhance the 2-3 shift. However, if unit is not being overhauled, DO NOT DO STEP #7.

STEP #7:

Remove center seal from direct clutch drum, Fig. #2A. Install expansion plug #24117 as
shown in Fig. #2A. This expansion plug must be driven in until it is flush with case or deeper.
