2004R Speedometer Gear Chart
200-4R Automatic Transmission Speedometer Gear Chart Infographic, includes drive gear, driven gear, rear end axle ratio and tire height.
*if the graphic does not load/show, scroll down to the bottom of this page for a table view.

If your numbers do not appear here, such as your tire height or rear end axle ratio, you can still calculate which driven gear would fit your application.
Collect your drive gear (commonly a 10 tooth), your tire height and your rear end axle ratio and head on over to the Speedometer Gear Calculator.
Once you enter all your pertinent info in the calculator it will tell you the driven gear needed for your application.
Keep in mind, 200-4R driven gears are only available in 26 - 31 tooth counts.
So if your calculated driven gear falls outside of those numbers, you may need to use a ratio adapter to get speedometer reading accurately again.
