Helllo Fellow Enthusiasts; If 71-73 Mach 1's were "Performance Cars"?!....Why are ONLY 3% Manual transmission ordered cars???!!!....I would NEVER own an automatic "Performance Car"!!!!...Were there that many "Girlie Men" in the early 70's!!!!....REAL MEN NEED 3 pedals!!!!!.....Mark
I can't speak for 71-72, but when I was looking at the "options" for my car (1973 Mustang Mach 1 H code) the Automatic Transmission was a STANDARD option, I don't know that it could be ordered as a manual (This being a 351-2V) I think only the Q Code for this year could come with a manual gearbox. Might explain why there are so few manuals!
Personally, my daily driver is a 6 spd, and there are days when I wish it was an automatic (specifically the ones where I'm stuck in LA bumper-to-bumper traffic) so having the 73 be automatic is what I wanted, something that I can just cruise in!
