Well The pictures on the web for the parts were not accurate. I picked up a
governor solenoid and the pressure/temperature transducer. Got them at the
local tranny repair shop, a lot cheaper than the dealer or on line, both for
$75.

Anyway swapped in the new parts flushed out the old fluid and replaced the
filter. All is well and the tranny is shifting like new and is not making any
noises.

Thanks all!
