how do u determine wether u have 2.73 or 3.23's. is there a code i can read on my car, so i know

thanx for any info.

 

Yes there is a code. Unfortunately I can't remember it. The "generic" way to check is. If your car is an auto and you can only put your shifter all the way back to 2nd gear you have 2.73's. If your able to shift all the way back to 1st gear you have 3.23's. There is a quick mod to allow you to shift back to 1st gear if you have 2.73's and you want that option. It just doesn't show up on the shifter console as 1st gear, actually it shows up as nothing lol.

 

GIVE ME THE LAST 8 DIGITS OF YOUR VIN # AND ILL LET YA KNOW TOMORROW....PM THEM TO ME IF U CAN

 

Look at your RPO codes. I have 3.23s.
