2004 Mach 1 Mustang Transmission TR3650
I Just recently bought a 2004 Mach 1 and I was having transmission problems a few weeks after I got it (5th Gear would constantly make a grinding noise). Thank god the car was under warranty so the dealership ended up giving me a new transmission. This one works well but i noticed that going 70mph in 5th gear I do about 2250rpm as opposed to my last transmission which did just under 2000rpm. Since I do a lot of highway travel this just got my attention. Is this something to be concerned about or anything?
