40 tooth 700r4 TH350 TH400 plastic Speedometer driven gear

Overview of 40 tooth 700r4 TH350 TH400 plastic Speedometer driven gear

Gears are mechanical elements that are typically used to transmit rotational motion and force. They work by meshing teeth with each other to change speed, direction of torque, or to transfer power between multiple shafts. Gears are an integral part of mechanical engineering and are widely used in a variety of mechanical devices.

Specifications of 40 tooth 700r4 TH350 TH400 plastic Speedometer driven gear

This plastic speedometer driven gear fits GM transmissions. It has 40 teeth. It works with 700R4, TH350, and TH400 models. The gear is made from strong nylon. This material lasts a long time. It handles wear well. The gear teeth mesh smoothly with the drive gear. This happens inside your transmission. The rotation sends the correct signal. This signal goes to your speedometer cable. The signal makes your speedometer show the right speed. The gear tooth count is critical. It must match your vehicle setup. Your tire size affects this. Your axle ratio affects this. The original drive gear affects this. Using the wrong tooth count causes problems. Your speedometer will show the wrong speed. It might read too high. It might read too low. A 40-tooth gear is a common replacement. People need it for certain modifications. Larger tires often need it. Specific axle ratios often need it. This gear is colored orange. The color helps identify it. Mechanics know the tooth count by the color. Installation is straightforward. You access the gear housing. The housing is on the transmission tailshaft. You remove the retaining bolt. You slide out the old gear. You slide in this new 40-tooth gear. Make sure it seats properly. Reinstall the retaining bolt. Tighten the bolt securely. Check the speedometer works correctly after. This gear solves speedometer calibration issues. It provides accurate readings. Use it when your current gear isn’t correct. Match it to your transmission type. Confirm your tire size. Confirm your axle ratio.

Applications of 40 tooth 700r4 TH350 TH400 plastic Speedometer driven gear

This plastic speedometer driven gear fits GM 700r4, TH350, and TH400 transmissions. It has 40 teeth. You need it when your speedometer reads wrong after changing your car’s setup. Changing tire size or axle gears changes how fast your wheels spin. This gear corrects the speedometer reading. It connects to the transmission output shaft. The speedometer cable plugs into it. As the shaft spins, the gear turns the cable. The cable sends the speed signal to your dash gauge.

Mechanics use this 40-tooth gear often. It’s a common fix for lifted trucks or hot rods. Bigger tires make the speedometer read slow. The gear speeds up the cable rotation. Then the gauge shows the right speed. Swapping to lower axle gears has the same effect. You need a different tooth count gear to fix it. Plastic gears are cheaper than steel ones. They are easier to install too. They wear out faster sometimes. But they work fine for most street cars.

You might need this gear during a transmission rebuild. Old gears can crack or lose teeth. This causes the speedometer to jump or stop working. A new plastic gear is a simple fix. Match the tooth count to your tire and gear setup. A 40-tooth gear is popular for many common modifications. Check your transmission model first. Make sure it’s a 700r4, TH350, or TH400. The driven gear slides into the housing near the tailshaft. It’s held by a metal retainer clip. Installation is usually quick. You don’t need special tools. Just remove the old clip and gear. Slide the new 40-tooth gear in. Secure it with the clip. Reconnect the speedometer cable. Test drive the car. See if the speedometer needle moves smoothly. Check the reading against a GPS app for accuracy. Adjust the gear tooth count if needed.

5 FAQs of 40 tooth 700r4 TH350 TH400 plastic Speedometer driven gear

What transmissions does this 40-tooth plastic gear fit?
This gear works with the 700R4, TH350, and TH400 transmissions. It replaces the original driven gear in your transmission’s tailhousing. Check your existing gear is plastic and the housing accepts this type.

Why do I need a 40-tooth speedometer gear?
Changing your tire size or rear axle gear ratio messes up your speedometer reading. The 40-tooth gear corrects this error. It makes your speedometer show the right speed again. Match the tooth count to your specific tire and gear setup.

Is plastic strong enough for the speedometer gear?
Yes. Nylon gears are standard for this job. They run quiet and last a long time under normal conditions. Avoid extreme heat or harsh chemicals. Plastic gears work fine in most street vehicles.

How do I install this driven gear?
Remove the retainer clip and bolt holding the old gear in the tailhousing. Slide the old gear off the speedometer cable. Slide the new 40-tooth gear onto the cable. Push the gear into the housing. Reinstall the bolt and clip. Ensure it meshes correctly with the drive gear.

Does the drive gear matter with this 40-tooth driven gear?
Yes. The driven gear (this plastic one) must match the metal drive gear on your transmission’s output shaft. Common drive gears have 7, 8, 9, or 10 teeth. The combination of both gears gives the correct speedometer signal. Verify your existing drive gear tooth count.
