The TREMEC Toolbox will help you simplify driveline setup, predict the effects of changing gear ratios and tire size, and calculate vehicle speed and RPM variables. This Toolbox is great for planning your rig, allowing you to see what kind of performance to expect from different combinations!

The TREMEC Toolbox contains:

• Driveline Angle Finder: Take the guesswork out of your chassis setup with this handy 3-step tool! By using your smartphone as a measuring device, the app will calculate each u-joint angle and provide an overall driveline operating angle with a Pass/Fail response. Designed for RWD vehicles equipped with a one-piece driveshaft.

• Vehicle Speed Calculator: Interactively determine your vehicle’s speed in any gear and any engine RPM for best performance. You can alter the axle gear ratio, the transmission gear ratio and tire size to see the impact in real-time.

• RPM Calculator: Determine what RPM your engine will run based on gear ratio, tire size, transmission and MPH. Try various combinations to come up with the best combination of gear ratio and tire size for your vehicle.

• Tire Size Calculator: Convert the funky P-Metric tire size (Example: 265/75R16) on the side of your tires to inches to simplify these drivetrain calculators!

Great but

Great app from TREMEC but needs a few more manual transmissions added to the library. Also, please add a “saved transmission” option. Otherwise we have to re input all the custom ratios all over again. 2 simple fixes!! Thanks guys.

Originally worked

My original version worked great but somewhere the angle calculator stopped. Great program until that.

Tremec app awesome

Priceless info. Awesome app pick your tremec from the selection and add your info and done. The driveline angle finder is correct also. Thanks to Dynotech custom driveshafts
