I just picked up a 1989 mustang with an AOD trans. This is the first AOD mustang I have owned. The trans was built with a Transgo shift kit and feels like it shifts firm as it should. Here are the issues: first if you leave it in overdrive or drive it shifts to 2nd at maybe 5 mph and 3rd by 10 mph. Is there a way to change this? Next issue is the guy I got it from says you can now hold the gears as long as you want and shift manually. how is this possible when I put it in first it seems to hold until I shift, but when I shift up which is D on the shifter it goes to 2nd then automatically shifts to 3rd around 4800 rpm. Being that there are only 3 forward gear selections (overdrive, Drive and 1st) is this my only option for shifting?
