My 94 FS 4-speed od trans works great but has been making a groaning noise ONLY at 60+mph. Backing off throttle stops noise and reapplying gas will return it. Replaced fluid (203000 miles), it was burnt and dark brown and I bought it with fluid way overfull. If I modulate throttle, noise will go away. It sounds a lot like coming from torque converter area, and sounds a lot like you have a dry or rusty bearing humming. Normal operation, I did have one-time rev rise to 3500 a while, dropped back down. Happened once. Please help :)

Save your pennies.:toothless
203,000 miles....:shocked
Overfull for who knows how long.....:twak
Dark and burnt fluid.....:doh0715:
A low groan at 60+mph.....:banghead
Dude, your tranny is dieing. I just went through the same thing with 130,000 miles, clean fluid, and at the proper levels. Wasn't long before my bronco wouldn't climb a hill on pavement without losing power and a horrible clunking sound that I could FEEL in the floorboard.
Got a new tranny now!:thumbup
