I have a 97 z28,was looking for gear #'s on it, any ideas where to look? Owners manual said to look in the console, nothing there.

 

Mine are located in the drivers side door jamb and I got a 97 also.
Here is the breakdown:
GU2 Axle, Rear 2.73 Ratio
GU4 Axle, Rear 3.08 Ratio
GU5 Axle, Rear 3.23 Ratio
GU6 Axle, Rear 3.42 Ratio

 

3.23s have "1" on the shifter.

2.73s don't.

 

that too but the label should be in the glove box

 

3.23's can select 1st gear, 2.73 can't.

Just trying to help, along with checking your RPO codes.

 

That can be fixed

 

yeah but it will still have 2.73's.

 

There is no label in the glove box..

 

Look on the information on the driver door.

 

Found it GU2... 2.73 ...

 

I know how you feel, my Formula has the same gears

 

im putting 3:73's in pretty directly.....its going to be a drastic change! i cant wait 2:73's to 3:73's

 

sorry.

 

Why GM even bother putting in 2.73's if they suck?

 

I've had 2.73's, 3.73's, and 4.10's in my car. 2.73's aren't "The Devil" that people make them out to be. The only time they seem to suck is initially off the line. On the highway, they rock. Maybe they just complement the power band of the LS1 better though?

BTW: only LT1 cars blocked of 1st gear w/2.73's. My LS1 w/2.73's CAN go into 1st gear right from the factory. That wasn't just a screw up either! They're all like that.
