With an automatic car a low gear isn't nearly as critical if you have the correct converter stall rpm. You can run awfully good with even a first gear multiple of 10. With a properly sized converter you can actually go too low first gear and run same or slower than with taller gearing.

Okay, makes sense. Thank you!
