How to Change Gear Ratios on Gran Turismo 4

Changing your gear ratio in the racing game Gran Turismo 4 increases your speed and changes the way your car handles. Break through your vehicle's stock top speed or be the first off the line by customizing your transmission. Gran Turismo 4 gives the option of automatically setting your transmission or individually tweaking each gear.

Instructions

1. Buy a Full Racing Transmission from the Gran Turismo tune shop for the car you want to modify. Your car should be four-wheel drive or rear-wheel drive and have at least a 700 horsepower engine.

2. Choose the settings icon from the race menu. You might need to start a race and immediately push "Pause" to get to the menu. Select the wrench icon next to "Transmission" to modify your gear settings.

3. Slide the adjuster to left for higher speeds. Move it to the right for faster acceleration. Set each gear down three sets from the preceding gear.

4. Change the auto setting for a broader adjustment. Selecting a high number gears your transmission to reach high top speeds. Lower numbers gear your car to accelerate quickly.

5. Test your transmission's gearing in a practice race. If you have difficulty making turns, your car might be too quick for that particular track.

6. Return to the shop to make any adjustments before you race.

Tips & Warnings

• Gear your transmission based on the race track. Tracks with quick turns don't require high top speeds.
