2007 f150 fx4 5.4 torque converter problems
 

ok mine is 75000 miles and i purchased a edge evolution programer and while in towing mode i blew the seal of my torque converter. sent it to ford and they changed it out. as soon i got it back i put the programmer back to stock and removed it so i wouldn't void the warrantee. 4 days later the same thing occurred so i don't think it could be the programmer that did it. any suggestions?
