Good post !!
I used to pay $20 for a tranny kit....gasket and filter from Napa.
Then one time I just needed a gasket as the filter was only one week old so I went to a local tranny shop and he sold me a gasket for $8.00 and I was happy.
Later I went to an actual tranny parts supply place and bought 4 gaskets for $5.00. Damn local guy.
Anyway, next time I'm going to see how much a filter is at that tranny parts supply place....betcha it's only around $5.00.
