WHAT REAR GEAR DOES MY CAR HAVE
You know when you are selecting gears, there is P,R,N,D etc.... In the same fashion, if there is a "1" in the same row with the P,R..... that you can select, then you have 3.23s. But if you don't have a "1" and have a "2" instead, you have 2.73s. Hope this helps.
If the guy who had the car before him did the first gear bypass, chances are he didn't put in a shifter plate which says 1. The guy before me did the bypass on my car, but never replaced the shifter plate, so I pulled one out of a junkyard. Just look at the RPO codes in the box. It will be GU and a number.....
