1986 Chevrolet El Camino

Transmission problem
1986 Chevy El Camino V8 Two Wheel Drive Automatic 78000 miles

When my car sits for a month or two, I lose 1 to 2 quarts of trans fluid. If I drive the car at least once a month, nothing leaks out. I have wiped everything down and can't find a repairable leak. Where is it coming from? My Corvette does this also.

A leak like that can come from several places. The dipstick tube O-ring, the pan gasket, the oil pump bolts gaskets, the oil pump O ring or the cooling lines. I'd check the lines first.
