i have an automatic 1967 mustang that will start but it wont go. when i change it into any gear it wont go. it doesn't move on parking which its obius. but when i put it in drive, reverse, or any other gear it wont go only if you push it but it will feel like in neutral. none of the changing gear's wires that make it change gears are broken or ripped. so what is wrong.
Most automatic transmissions from the '60s were pretty straightforward. If the fluid level and condition are good and the shift linkage is still working right, there isn't much outside the transmission to go wrong. The kickdown linkage only affects upshifting and downshifting.
Sounds like low transmission fluid level. Have you checked your transmission fluid? Any automatic transmission vehicle won't move if it doesn't have the right amount transmission fluid. If it turns out there's plenty of fluid then it could be the shifter is off set or the transmission is bad. Good Luck
