Governor Inspection
Check operation of the governor valve, weights and
shaft. The valves and weights should slide freely in
the governor body.
r Components
Check the governor drive seal rings. Replace the
seal rings only if they exhibit wear or damage. Be
sure the seal ring grooves in the drive are in good
condition as well.
Inspect the governor support and oil pressure
tubes. The tubes must not be pinched, kinked, col­
lapsed, or distorted. Blow them out with compressed
air to clear them. The tubes are designed to be a slip
fit in the piston retainer boss. Do not modify the tube
ends in an' effort to make them fit tighter. Both
tubes are an integral part of the support D©
not attempt to remove them. Replace the sup­
port and oil tubes as an assembly if either part
is damaged.
Check condition of the governor snap rings. Re­
place any snap ring that appears bent or distorted, or
condition is doubtful.
Inspect the governor body for damage. Replace it if
cracked, or if the bores are worn.

ATF Plus transmission fluid during assembly.
(2) Install new seal rings on governor drive as fol­
lows:
(a) Compress (squeeze) each seal over center be­
fore installation (Fig. 42). This action provides
tighter ring fit on drive.
