I'm working on my 86 AT.  I looked at the governor, and was surprised by
its small size and simplicity.  How does this thing work?  It looks like
the only moving parts are the weights which simply operate a couple of
check ball looking valves.  I expected something that would provide
variable input to the trans about output shaft speed, and I can't see how
this gadget would do that.

The other question I have is about the seals I need to replace that cause
the ATF and final drive gear oil to mix when they fail.  Where are they?
