a 727 tranny leak question

A lot of good suggestions here. If I could make a suggestion here's one. Clean the affected areas off realy really good with brake clean & compressed air if you have it, then spray the areas around the pan gasket & shift & Kickdown seals, cooler lines & don't forget around the bottom of the dip stick tube with ordinary athletes foot powder spray. Spray it on good & wet & then drive it as normal until it leaks. The powder will show the leaking area & should still be dry where it doesnt. Or you could add some oil leak dye in it & check it with a uv light if you have acceaa to one. Good luck!
