Have a 1996 mustang gt with an automatic transmission. I recently checked the gear ratio and it was 3 rotations of the drive shaft to 1 rotation of the tire. I'm not sure what that makes the ratio but I think it's stock. Can you change the gears on a gt with automatic transmission? To something like 3.73 or higher?

What I'm hoping to accomplish is a much faster acceleration from 0-40ish. It seems sluggish till it hits 30mph then you can feel the acceleration really pick up.

The transmission does have a shift kit installed (or so I was told) and shifts more like a manual would, but I don't know if that has anything to do with the sluggish acceleration.

I will say it still accelerates faster than previous car, but it isn't quite what I'd like.

The gear ratio should be on the dif case cover but I believe you have 3.27 ring and pinion 4.10 for an automatic is normal

I have 4:10s in my auto. I love them.

Im looking at 3.73s for my standard 4.10 and my first gear would pretty much be non existent

go 4.10 with the auto, the auto has taller gears in the tranny the manuals making a good fit. 3.90 is also an option.
