23. Measure the overdrive clutch clearance using
a feeler gauge between the selective snap ring
and the backing plate (See Figure 182).
24. Refer to Figure 182 for the specification as the
2 plate and 3 plate stacks are different.
25. Change the selective snap ring as necessary to
obtain the proper clearance. The selective snap
rings available are listed in Figure 182, along
with the OEM part number.
26. Install the pre-assembled coast clutch housing
and overdrive gearset as an assembly using the
required installation tool 307 S383, as shown
in Figure 183. Ensure that the number 5 thrust
bearing is still in place on center shaft.
Caution: The overdrive one-way roller clutch
may be damaged if this tool is not used on the
"PTO" equipped transmissions
27. The assembly will have to be rotated back and
forth to engage the center shaft splines and all
of the overdrive friction plates, and extra care
must be used during installation to avoid any
damage until fully seated.
