It would most likely be a/ worn clutch/s or a shift solenoid. ( yes!!! automatic transmissions have clutches)
if its an automatic, and a four speed, E4OD?
Yes it will but you may have some computer and driveline issues going from an a4od to an e4od
E4OD. Electronic 4 Speed with OverDrive.
3 speed automatic ( C6 ) 4 speed automatic ( E4OD )
If the F-150 has the Ford E4OD transmission, then yes, it will fit into the Ford Bronco. If it has the E6 automatic, however, you may have some issues.
If you are speaking of the full-size Bronco, then no. The automatic in the Bronco was either the E6, AOD, or E4OD, none of which were utilized by the 1985 Ranger. The Ranger used a few different types of Mazda and Mitsubishi transmissions in 1985.
Basically the E4OD transmission is an electronic 4 speed transmission with overdrive.
E4OD(transmission) with C6 in overdrive
its electronic. no mod.
e4od
The 1994 takes Mercon transmission fluid
I believe that is an E4OD automatic transmission
