Ford ZF 5 speed transmission update

If the tranny had just been rebuilt, I could see wanting to put the "best" oil possible in it, but with this one that's already making noise, I suspect the $$$ for the oil could be better used by finding out what's REALLY wrong.

Good Luck, though, I hope the oil DOES work for you, that would sure beat pulling the tranny!

And ornery enough to repair them myself.

My wife says it's a DISEASE!

I think the point Bob is trying to make is, don't ignore a failing part untill it destroys the transmission. My experience with that was with a Dodge 3 spd OD trans. This OD transmission is the old Chrysler 4 spd direct drive car transmission modified into an OD transmission. They reworked the gear ratios so you shift 1-2-4 than back to 3 for the OD ratio. The original design of that trans was that you would shift 1-2-3-4 and spend 90% of your time in 4th gear, that couples the input shaft directly to the output shaft. With no load on the gears/bearings during the 90% of the time you are in 4th gear. When they modified this trans into an overdrive trans, You shift 1-2-4 direct,than back to 3 OD which loads all gears/bearings for 90% of your driving miles. after 80,000 miles of running 3 OD, the trans developed an ever worsening bearing noise. I pulled the trans and found that the plastic ball cage in the input shaft bearing had worn out from the constant load of the 3 OD gear. Chrysler had discovered the problem,and the $15 replacement bearing had a steel ball cage. Had i continued to ignore the noise, I suspect I would have destroyed the transmission, atleast have broken gears and probibly the case.
