9 - 22 OVERDRIVE<br />
29. Remove retainer and select and Install a gasket .003" to<br />
.005" thicker than clearance indicated by feeler. (Gaskets are<br />
available in four different thicknesses.)<br />
30. Place bearing retainer in position, Install 3 cap screws and<br />
tighten, making sure oil drain hole in flange is aligned with<br />
hole in case.<br />
31. Install the transmission cover and gasket. The cover gasket<br />
has three vent holes and must be Installed with holes to rear<br />
of case. The cover has one vent hole and is Installed with<br />
hole to front of transmission. See marking on cover.<br />
32. Complete balance of assembly as outlined under<br />
"Installation of Adaptor Plate, Solenoid Pawl, Sun Gear<br />
Control Plate and Blocker Solenoid, Sun Gear, Shift Rail<br />
and Fork, Clutch Cam, Pinion Cage and Overdrive Mainshaft",<br />

TRANSMISSION AND OVERDRIVE<br />
Installation<br />
1. Install two headless screws or studs in engine end plate to<br />
assist in supporting the overdrive and transmission at Installation.<br />
NOTE: Before Installing the overdrive and transmission to<br />
engine rear support plate, check cylinder block rear support<br />
plate very carefully for tightness and alignment. This is especially<br />
important in cases where the car has been subject to<br />
chronic transmission trouble, noisy and jumping out of gear.<br />
Make a similar check of transmission clutch bell housing.<br />
In lieu of highly precise equipment, use a steel straightedge to<br />
check steel rear support plate and a surface plate or other flat<br />
surface to check the front face of clutch bell housing. Both units<br />
should be flat and in plane within .005".<br />
Be sure to check position of clutch driving plate and see that it<br />
is perfectly centralized within the clutch assembly. This can be<br />
done by using the J-449 aligning arbor or with a standard main<br />
drive gear if arbor is not available. If this precaution is not taken,<br />
difficulty will be encountered when Installing the transmission<br />
and the front end of the drive gear shaft and pilot bearing in the<br />
flywheel will be damaged.<br />
2. Rotate clutch collar and throwout bearing to position<br />
for proper alignment with throwout yoke on transmission.<br />
3. Tighten all rear engine support plate to block screws.<br />
4. Bring the overdrive and transmission assembly to<br />
position where the main drive gear (clutch shaft) is<br />
aligned with bore of clutch throwout collar, then carefully<br />
push transmission forward to enter drive gear<br />
splined shaft through grease retainer leather washer,<br />
splines of clutch driving plate and into pilot bearing in<br />
flywheel.<br />
NOTE: During this operation the main drive gear must<br />
be relieved of all over hanging weight of the transmission<br />
until the bell housing engages the dowels on engine<br />
rear support plate. Before transmission assembly<br />
is moved up against rear support plate make a last<br />
inspection to verify that end face of throwout collar in<br />
clutch is properly aligned with throwout yoke on transmission<br />
and that oil seal lip has not turned under.<br />
CAUTION: Alignment of bell housing with engine is<br />
controlled by the sleeve dowel in the upper left location<br />
of tile bell housing attaching bolt circle and by the<br />
dowel bolt at the lower right location viewed from rear<br />
of car. Make sure that the former is in place and<br />
entered in bell housing hole before tightening bolts.<br />
Install lower right bolt (dowel bolt) first. NEVER<br />
grind or otherwise reduce the diameter of the dowel<br />
bolt to facilitate Installation.<br />
5. Remove the two headless screws or guide studs, J-2969.<br />
6. Install remaining clutch bell housing bolts and screws<br />
and tighten with a torque wrench to 40-45 foot pounds.<br />
7. Complete remainder of Installation by reversing the<br />
order of removal of the remaining parts. Check adjustments<br />
and refill transmission and overdrive. A total of<br />
3-1/4 pounds of lubricant is required for the single<br />
lever type transmission and 3 pounds for the double<br />
lever type transmission.
