depending on what tranny it has in it normally about 12-13 quarts i would start with about 10 quarts and then start it and run through the gears and check it and add as needed
Be careful on this. I did it to myself . I install my transmission back on my 89 bronco and found out I didn't lock in the converter right and damage it. Cost me an extra $700 to repair the pump and new converter had the same systems as you.
have your transmission and torque converter checked
10.5 Quarts if the torque converter is dry also.
An AOD transmission can go into a 91 Bronco with a little fabrication.
yes
Ford discontinued the Bronco in '96.
a complete donor truck
Its an A4LD.
I believe that is a ( C6 ) 3 speed automatic transmission with the 351 in a 1989 Ford Bronco
I had a 1989 automatic Bronco II and this did not bode well. I can't say which of these problems produced the hesitation, but the first issue was transmission failure. After I fixed that, I still had problems (or maybe it was sometime later) and I ended up needing an entire engine rebuild. My advice: unless you can fix a Bronco yourself, you shouldn't own one. They eat money after a certain point.
The C5 Transmission
Sure, but you will have to change many, many, many other parts along with the transmission. I would suggest purchasing a 1990 Bronco like yours that has a standard transmission to use as a parts car.
