Re: Gear ratio

Probably

Most likely came with 3.23 if it has G92, 2.73 if not

MOST CERTAINLY, it NOW has whatever you see while you're changing the fluid, as any sensible person would do... there is NO SUBSTITUTE for just popping the cover off and LOOKING AT IT

Re: Gear ratio

Jack up the back end, rotate the tire 10 times and count how many times the drive shaft rotates, and then do the math.
