A buddy of mine has 2 1990 bronco ii a4ld trannies, and his 1993 explorer just dropped a Trans.
I know the ex uses a different a4ld, with an additional solenoid or two.
So it stands to reason that an older ECM lacks the controls for these an additional solenoids, so it won't work.
But in his case, if the trans runs without these inputs, it'll shift fine because the trans, and ECM-neither know otherwise
I'm by no stretch of the imagination an auto tranny guy.
I know the bells share a bolt pattern, any other deal breakers?
