TH350 Transmission Leaking from everywhere!

[hotwls13]

My new to me 70 GMC LWB TH350 is leaking a LOT. It is also an ugly mess that has evidently been leaking for YEARS. So far I have found what appears to be leaks from:

- Speedo Bullet
- Vacuum Modulator
- Pan
- Shift Selector

I have picked up the following:

- New Speedo Bullet (with seal and O-ring)
- New Redline Vacuum Modulator (with hose)
- New Shift Selector seal
- New Pan Gasket and Filter kit (filter is the metal type, gasket the rubber type)

ANything I'm not thinking of? Maybe Filler O-ring?? The rear seal is NOT leaking surprisingly.

Should I try to get a replacement Pan Gasket (either Fel-Pro or Cork with metal inner part)??

I also may need a new "Driven Gear" as it may have a groove worn in it. They are hard to find around town so I will have to order one once I pull it and find what color/size I need.
