OK, I know it V-drive forum, but I'll pull a V-drive with it!
Got a 2001 3/4 ton Suburban, it turns 2400 RPM at 70 MPH, does it look like I have the 3.73 or 4.10 gears? If the speed and rpms can't establish, what code am I looking for in the glove box?
Thanks

There IS a tag on the housing somewhere. Usually under a bolt. Are your RPM/speed numbers in or out of overdrive?????? An old rule of thumb was a 4.11:1 gear would be about 1/2 RPMs to speed. Example, 3K would be about 60. This isn't exact because of things like tire size, (height), but approximate. If your numbers were in drive, not overdrive, I would guess the 373 gear. But look around on the differential, I'll bet there is a tag...........There is also a formula to figure it to the knats ass with the proper data..........MP
