Tremec Gear Calculator

For automotive enthusiasts, mechanics, and performance tuners, understanding gear ratios and how they affect vehicle performance is crucial. The Tremec Gear Calculator on our website provides a professional and user-friendly tool to calculate Tremec transmission gear ratios, top speeds, and torque outputs.

This tool is ideal for anyone working with manual transmissions, especially those upgrading or tuning Tremec gearboxes for performance cars, racing, or custom builds. It simplifies complex calculations and ensures precise setup for optimal performance.

How to Use the Tremec Gear Calculator

Using the calculator is straightforward:

1. Enter Engine RPM – Input your engine’s revolutions per minute.
2. Enter Tire Diameter – Provide the diameter of your vehicle’s tires in inches.
3. Input Gear Ratios – Enter the Tremec transmission gear ratios for 1st to 5th/6th gears.
4. Enter Final Drive Ratio – Input the rear differential ratio.
5. Click Calculate – The calculator computes vehicle speed at each gear and torque delivered.
6. View Results – Results include top speed per gear, effective gear ratios, and performance metrics.

Required Inputs:

• Engine RPM
• Tire diameter
• Gear ratios
• Final drive ratio

Expected Outputs:

• Vehicle speed per gear
• Effective gear ratios
• Torque calculations

Calculation Logic

The calculator uses the following formulas:

Speed (mph):$$\text{Speed} = \frac{\text{Engine RPM} \times \text{Tire Circumference} \times 60}{\text{Gear Ratio} \times \text{Final Drive} \times 63360}$$Speed=Gear Ratio×Final Drive×63360Engine RPM×Tire Circumference×60​

Torque at wheels:$$\text{Wheel Torque} = \text{Engine Torque} \times \text{Gear Ratio} \times \text{Final Drive}$$Wheel Torque=Engine Torque×Gear Ratio×Final Drive

Where:

• Tire Circumference = $\pi \times \text{Tire Diameter}$π×Tire Diameter
• 63360 converts inches per hour to miles per hour

This ensures accurate performance metrics for each gear in the Tremec transmission.

Practical Example

Suppose a car has the following specs:

• Engine RPM: 6000
• Tire Diameter: 26 in
• Gear Ratios: 1st = 2.66, 2nd = 1.78, 3rd = 1.30, 4th = 1.00, 5th = 0.74
• Final Drive Ratio: 3.73

Step 1: Enter all values into the calculator
Step 2: Click Calculate

Output Example:

• 1st Gear Speed ≈ 45 mph
• 2nd Gear Speed ≈ 67 mph
• 3rd Gear Speed ≈ 92 mph
• 4th Gear Speed ≈ 120 mph
• 5th Gear Speed ≈ 163 mph

Wheel torque can also be calculated for each gear to optimize acceleration and performance.
