My goodness, theose "Blue Ovals" really suck, don't they? No, they bite. I still have nightmares of my old 351 V-8 Bronco. Since this is an oil site, I must say I never had an engine-block related problem. But the electrics, the clutch, and the chassis: ohhhh, I could never make it out of the driveway! And remember the Firestone/Ford tire scandal? My Bronc ate tires like there was no tomorrow. I was lucky not to have it flip because of a tire blowout, I always caught the delaminating tires before they could kill me. Conclusion: Blue Oval: the worst darn thing on Earth!quote:

I remember way back in '96 or '97, I had a '90 Ford Ranger pickup with the 4.0l enigine and auto tranny. I had a transmission service done and after i got home, I checked the fluid level. It looked a little high to me, but I wasn't sure, because it's so **** hard to get an accurate reading with those tranny dipsticks. You would think in this day of modern technology a better system would have come around by now...
Anyway, I took off up a long steep mountain pass the next day in the middle of summer. The next thing I saw was a huge cloud of smoke behind me. I pulled over, popped the hood, and the tranny was puking the fluid right out the dipstick all over the exhaust manifold. Now I new the **** thing was overfilled.
I continued to the top, and stopped and went for a hike. After I got back a few hours later, I rechecked the fluid level and it was right where it was supposed to be on the dipstick now.
Thats about the only Ford compliment I can give after having that Ranger.....
Listen to Ray's wise words, Grasshoppers. The areated ATF is reducing the transmission line pressure. Overfilling will kill a transmission as surely as underfilling will.quote:
Overfilling an AT can cause aeration in addition to the factors already discussed. Air is a poor substitute for lubrication as well as a poor power tranfer medium in an AT. Ergo, the effects of overfilling can be as detrimental to tranny life as underfilling. (Aeration could also be why you notice smoother shifts with an extra liter of ATF, too, since foam is being used as the power transfer medium at the clutch facings. But, the "advantage" could be short-lived if it results in premature clutch facing wear.)
