🧭 How to Use the Tremec Gear Calculator (Step-by-Step Guide)
Using the calculator is simple and does not require any technical background. Follow these steps:
Step 1: Enter Engine RPM
Input the engine’s revolutions per minute. This represents how fast your engine is spinning.
Example:
- 3000 RPM
Step 2: Enter Gear Ratio
Add your transmission gear ratio. This determines how engine power is reduced or multiplied before reaching the wheels.
Example:
- 3.73
Step 3: Enter Final Drive Ratio
Provide the differential (rear axle) ratio. This further multiplies torque before reaching the wheels.
Example:
- 3.42
Step 4: Enter Tire Diameter
Input your tire size in inches. Tire size affects overall speed and wheel rotation.
Example:
- 26 inches
Step 5: Click Calculate
The tool will instantly display:
- Vehicle speed in mph
- Wheel RPM
- Torque ratio
Step 6: Analyze the Results
Use the output to evaluate performance changes and decide whether adjustments are needed.
