Hi, I had read somewhere that if you put an awd trans case in a ranger when u do a 5.0 swap and u leave the ranger differentials in the ranger u wont have a park gear, that the diffs have t be from the explorer? my 98 will drift when I park on a grade. anyone with knowledge on this please let me know. she doesn't lie to idle when she first starts, she is efi not carbed. once running she is fine, has one trouble code...runs too lean, no other codes. been told it must be a leaky intake that seals once it warms up?
