how can I find out what gear ratio is in a 1994 Firebird V6 with a posi, disc, rear end without looking at the axle?

can I get some sort of range?

P.S. this is third gen related because I want to put it under my car

 

By looking at the axle, inside the cover.Between 2.73 and 3.73. Most likely, 3.23 or so.

If it matters to you what the ratio is, you'll look. If you're not willing to look, then it must not matter very much, and you'll just take whatever you get.

 

It's probably at least 3.23. If it's a 5 speed manual car, there's a better than average chance it's 3.42.

 

im sorry guys it under a 96 Firebird not a 94 and I can't get under it its on the ground (no wheels)

its an automatic

 

None of that changes anything about knowing what gears are inside there.

If it really matters to you, you'll quit making excuses, and figure out a way to look.

 

it has ABS, is that a problem?

 

Not if it's the 3-channel kind. It's just a sensor sitting there with nothing hooked up to it. Harmless.

If it's the 4-channel kind though, there will be 2 separate hydraulic brake lines, since each wheeel is individually controlled. That would require a little plumbing to get to hook up to your brake system. But I don't think those had come out yet in 96, although I could easily be wrong.

 

You could always check the RPO codes listed inside the car for the gear ratio.
