Installation
VALVE BODY INSTALLATION
1.
Verify that park/neutral position switch has NOT been installed in case. Valve body cannot be installed if switch is in place.
2.
Check condition of 0-ring seals on valve body harness connector (Fig. 15). Replace seals on connector body if cut or worn.
Manual Lever Shaft Seal Installation
3.
Check condition of manual lever shaft seal in transmission case. Replace seal if lip is cut, or worn. Install new seal with 15/16 deep well socket
(Fig. 16).
Accumulator Piston Components
4.
Check condition of seals on accumulator piston (Fig. 17). Install new piston seals if necessary.
5.
Place valve body manual lever in low (1 position) so ball on park lock rod will be easier to install in sprag.
6.
Lubricate shaft of manual lever with petroleum jelly This will ease inserting shaft through seal in case.
7.
Lubricate seal rings on valve body harness connector with Ru-Glyde, or petroleum jelly.
8.
Position valve body on case and work end of park lock rod into and through pawl sprag. Thrn propeller shaft to align sprag and park lock teeth if
necessary. Rod will make click noise as it enters pawl. Move rod to check engagement.
CAUTION:
It is possible for the park rod to displace into a cavity just above the pawl sprag during installation. Make sure the rod is actually engaged in
the pawl and has not displaced into this cavity. If the rod enters the cavity during installation, it will become bent when the overdrive bolts are
tightened. The rod will then have to be replaced because it is not repairable.
9.
Install accumulator springs and piston in case. Then swing valve body over piston and outer spring to hold it in place.
10.
Align accumulator piston and outer spring, manual lever shaft and electrical connector in case. Then seat valve body on case and install one or
two bolts to hold valve body in place.
