Follow up. Lulubelle is approaching 400,000 miles on the original engine with the front end rebuild and still rocking the solid and very reliable 6F50 transmission originally mated to the engine. This 6F50 transmission has suffered no failures at all. Keep in mind it had continuously receive 30K transmission fluid 3X drain and fills. I am personally on my 3rd Ford Edge passing 200,000 miles and have accumulated over 1,000,000 miles on Ford Edges with not one single water pump or transmission failure on any Ford Edge I have ever owned.
