Default (((HELP)))What Size Gears Do I Have????

I know I should know this but how can I tell what size gears my 98' GT AOD(stock) has? I have the door jam sticker and the little aluminum tag still on the pumpkin but do not know how to read it. I know its a no brain-er but I need some help please. Thanks!

prop the back end up and turn the wheels once and see any many times the drive shaft turns

the stock is 3.27 so if it turns 3 and a fourth times you have stock

The tag on the rear end will tell you.

prop the back end up and turn the wheels once and see any many times the drive shaft turns

the stock is 3.27 so if it turns 3 and a fourth times you have stock

if it turns 4 times or more then you got the 4.10 or up

you can do the math

Try this im not sure about the sticker

stock for a 94-98 is 2.73

whatever they are, swap them out for 4.10s
