Can I change my 3-speed automatic to a 5-speed automatic in a 66’ Mustang coupe?

Asked by Mihajlo Jul 28, 2020 at 02:29 AM about the 1966 Ford Mustang Coupe RWD

Question type: Maintenance & Repair

I’d like something more up to date instead of
the old-stock 3 speed auto. And how do I do

Not a 5 speed, Maybe a 4 Speed AOD. Check with your mechanic or a transmission shop.
