Bill:

Check the cooler lines where they go though clamps on the engine oil pan. when the rubber liner goes, the steel line rubs on the clamp and will eventually perforate where it contacts. It will ONLY leak on acceleration, leaves no puddle and no trail, but will run you out of trany juice.

Mine did exactly that, the only clue as a drop of tranny fluid on the oil pan lower edge. Ran out freely if I lifted the line.

The line is no longer available, so you will have to braze the hole up.

Other than that, the only place they leak is at the front seal (fluid dripping off the bell housing) or servo covers (fluid on the tranny pan edge). Stay away from any shop that tells you you need a tranny rebuild for a leak! That tranny, cranky as it is, should go at least 250,000 miles with nothing more than fluid changes and a band adjustment.
