Jack up one tire if you have an open diff, or both tires if you have a working posi or locking differential. Rotate the tire one full revolution for posis and lockers and 2 full revolutions for open diffs. Carefully count the number of full revolutions the driveshaft makes. This is your gear ratio. In other words, if the drive shaft turns 3 ¾ turns, you probably have a 3.73 gear ratio. Turning the tire for twice the number of full revolutions and dividing the drive shaft revolutions by two will give you a more accurate reading.

On the car, there is a Tremec TR3650-4 transmission, I'm trying to figure out the speed sensor I need as the speedomer is 4.6 time to fast.
Again, thanks a million

Hi jrherald420, it is a TR3650-4, the label is clearly visible, Why do you seem so surprised?

I wasn't 100% sure about the 96-98 so I didn't comment on those.
