Fig. 7A4-165 Installing Direct Clutch Assembly
NOTE: If transmission is in car, assemble the front servo
group as shown in Figure 91 and install this group of
parts into the front servo bore in the case and hold. Slip
a length of straight, smooth, clean feeler gage or shim
stock (about .020") between the spacer plate and the
front servo piston to temporarily retain the front servo
group in its bore as shown in Fig. 7A4-175.
9. Install O-ring seal on electrical connector.
10. Lubricate and install electrical connector with lock
tabs facing into case, positioning locator tab in notch on side
of case (Fig. 7A4-176) and connect detent wire to electrical
connector (Fig. 7A4- 177).
The teflon ring allows the front servo piston to slide very
freely in the case. This free fit of the ring in the bore is a
normal characteristic and does not indicate leakage during
operation. The teflon ring should be replaced only if it shows
damage or if evidence of leakage during operation exists.
