I have a 64.5 mustang convertible 260v8 w/ auto transmission. It's a great little car, very clean. Problem is it does not get much use, just sets in the garage most of the time. The last time I got it out it would not shift into drive. Just stays in 2nd. I drove it around for a little while thinking maybe once it warmed up it would help, but no luck. Any suggestions, outside of taking it to the fix-it shop. I've always done my own mechanical work, but have no experience with auto transmissions insides. any help would be great....
