stupid question
 

how do i change my gears to 4.10 just take it to the shop and does anyone know the original setting on a 2001 v6 auto

i not really sure i think its 3.55 but dont take my word for it
correct me if im wrong.

nope it is 3.27

yeah that sounds about right

See my post in your 4.10 thread.

You'll also need to correct the speedo. If you have an auto then a tune is the only way.
