Hope someone can help i have a fmx tranny behind a 289 both out of the same car 65 ford fairlane. Since reinstalled it the tranny has leaked from the bell housing area i have replaced seals and bushings ive even changed the converter . WITHIN TWO OR THREE weeks it started leaking again as for as i can tell there is no slack or vibrations in shaft if any body has a clue it would be helpful thanks rick

 

When you replaced the old seals, did you notice any wear or grooves in the shafts? If so, then that is most likely your problem. The wear/grooves aren't allowing the seals to seal properly. Alternatively, pick up some UV dye from your local auto parts store and put it in the tranny fluid. Then clean up the leak with some brake cleaner and drive the car around for 100-200 miles. Then whip out a black light and start hunting for the glowing spots. Good luck...
