Ok... So im getting gears... I have an Auto, so i went with the 4.10's... I know my car has Traction Control... Is this the same as the "Traction Lok" i can buy? I know it stops the wheel spin ( No Fun)...Since i have the Traction Control will i need to buy anything else to make the 4.10's work with my car... All i did was buy the gears, so is there anything else i will need to buy before i tear into the car?
