How match would an 83 ford atomatic transmission cost? and would it be possible to shift gears from first second and then into drive for 3rd and then into overdrive for 4th and 5th and it still work ?
Sounds like your trans needs some help. Are you looking for a used transmission, rebuild or new? A used one from a salvage yard will be in the hundreds, a rebuild one, $1500-$2500, and a new one $3k or more. Are you installing or having someone else do it? Not really worth replacing/fixing if your Ford is a '83 IMO.
