i got a 1990 ford bronco with the 351 windsor and a automatic transmission not sure wich tranny dont know much about automatics but its got enough fluid but clunks into reverse and sometimes drive hard and while driving it makes like a howl noise and sometimes will sound and feel like something is loose and moving around but it doesnt slip or hesitate i checked all the tranny bolts tourgue converter bolts and trany mount and there all good
You might also check your gears. My truck had a loud howling sound while driving down the road too. Turns out I had lost a gear tooth and was just flying around in the housing. Not good.
When checking the u-joints and pinion yolk, besure to have it in netral. If the yolk is loose, you are supposed to change the crush sleeve. But I have seen and done it with out replacing it. If you have a yolk, you can hold it with a big pipe wrench and tighten the nut with a socket. If you have a disc yolk, you can put two bolts in and place a bar between them to hold it.
so i checked all my u joints and tighten the pinion yolk up and yes it does have the overdive button but im starten to think that it is my differential because the howling has not only gotten worse but now its clunking really bad just when im drving not 100 percent sure yet tho
