Well I asked and you guys recommended! After using my local guy to rebuild the trans in my pristine 64 Sport Fury convertible 426-S it lasted all of two weeks. Actually it never was right. I did what I should have done in the first place and had Keith Long (727specialist) build me one utilizing one of his nice cores with 67 & up internals and a new 2800-3000 stall converter. It arrived in a very reasonable time frame with output flange included. I installed it this past Friday evening, filled it with ATF4, hit the key and breathed a sig of relief after good firm engagement in R & D. Test drive was the best I had witnessed after owning this car for 15 months. I was finally happy. Back on the lift and up there were zero drips, dry as powder. Again, elated! 7 hours later I was able to attend our last big show here in my area where the Sport Fury garnered best in class out of 22 cars. Thank you Keith for putting an end to my nightmare and providing me with a trans I know will last me for a VERY long time! And thank you to the Mopart's community that led me to the right decision!
