Also the weight of a 2001 firebird 3.8L v6 is over 4,000 lbs? I looked on the driver door. Damn that is a fat car

Re: How do i tell how many rear drive gears i have?

your car's weight should be around 3300-3400 lbs. l doubt it is 4000lbs.

about gears, l doubt you got 2.73 or 3.23s.. v-8s have those gears.

but check your driver side door anyway.. and if you see GU2 it is 2.73, if you see GU5 it is 3.23s.

Re: How do i tell how many rear drive gears i have?

i looked on the driver door and the first weight was over 4,000lbs..I was hoping my car wasnt that heavy

And if my car shouldnt be 2.73 or 3.23 what should it be? Will i still have GU2 or GU 5 if its a v6?

Your car should weigh around 3600lbs and GU2 or GU5 are RPO codes for your gears. They are the same code no matter if its a V8 or V6 cause it only pertains to the gears not the engine. You may also have GU4 which I believe is 3.08's.

No problem. Happy to help and doodad I basically repeated exactly what you posted and added in one more ratio it could be. So I didn't actually share anything else your didn't already know.
