Problems?

You put in 14 PINTS or 14 QUARTS. Trans fluid comes in QUART bottles,if you put 14 of them in then you are over ful by about 5-6 quarts which will definitely make it leak. 18 PINTS is 9 Quarts,2 pints per quart.A fresh 727 with a new stock convertor will hold no more than 9 QUARTS,being that you had a used convertor that is probably a little smaller than the stock one it should only take about 8 QUARTS.
