transmission losing fluid and shifts hard

Hey Jeff, Make sure you either add fluid or stop driving it, you are ultimately doing damage when it's low on fluid. These normally leak in a few places like the cooler lines, output shaft seal and the front pump seal. You or someone should inspect it to determine where it's coming from. But first, you may want to add fluid and see if the shifting corrects itself, otherwise, it may not be worth fixing the leaks only to have the transmission issues persist. Best of luck, Bret
