2006 mustang gt automatic vs manual

What about driving my Mustang like a Mustang? Stock automatic transmissions in Foxbody Mustangs only allow you a drive in gears 1, 2 and an over drive. ThereGT Performance Mods - GT auto vs Manual gear ratios.. - hi all! can anyone list the 1st to 5th gear for both how far off is the auto vs. manual? thanks! With an automatic, you have to have the power go through a torque converter before exiting the transmission and running through the drivetrain.
