<VV> PG Problems

[Jim Davis]

E-clips usually fail because of a leak in the modulator vacuum line, or 
when the modulator fails.  You are correct in that there is no 
connection between the e-clip failure and the governor's gear having no 
teeth.   I only included the e-clip info because he asked about it.

If the PowerGlide stack has to much play or to little, it won't shift.   
The fluid for the drive clutch comes through the front pump housing and 
goes between the two steel slip ring seals into the drive clutch.  If 
the stack moves more than 1/4" from where it is supposed to be the slip 
rings will cover up the orifice and no fluid will get to the clutch.

If the teeth on the governor gear were missing, I wonder where they went?  Lots of very small passages in the PowerGlide valve body.
