I would say that 90% of the trans leaks brought to me are not the pan. The fluid level is well over 1" above the pan rail when parked. Clean the entire area with brake clean, blow off with air. Dust baby powder around the trans and watch. The power will wick up the fluid, you'll see the leak area. Look carefully and follow the trail. Prime candidates, Low reverse band apply pin (can be RTV sealed in the car with a thin putty knife), dipstick O-Ring,valve body case seal, valve body throttle shaft seal,tail shaft bolts (add teflon pipe sealer), trans line fittings. Other areas that probably won't look like a pan leak are speedo cable o-ring, speedo cable itself, tail shaft snap ring access cover, output seal. These are all repairable in the car. The only leaks not repairable in the car are front pump and or seal,converter itself.
