Replacing Your Speedometer Transmitter in Six Speedy Steps
Just as you rely on your speedometer to tell you how fast you're going, your speedometer relies on your speedometer transmitter to tell it how fast your transmission gears are rotating. Also known as a vehicle speed sensor or VSS, this component is a magnetic coil usually found at the bottom of the transmission. If the transmitter starts failing, your speedometer won't be able to give you accurate readings—and that could lead to being pulled over by traffic police for speeding. Spare yourself the legal troubles and repair expenses by replacing the speedometer transmitter yourself.
Difficulty Level: Moderate
Here's what you'll need:
- Floor jack
- 2 jack stands
- Wheel chocks
- Open-end wrench
- New speedometer transmitter
- Vehicle owner manual
Step 1: Make sure you are parked on level ground and that your engine has cooled over a few hours. Place the wheel chocks behind your rear wheels then use your floor jack to raise the front of your vehicle. Set up the jack stands underneath the pinch welds then lower your vehicle until it's resting securely on the stands.
Step 2: The speedometer transmitter is usually found sticking out of the bottom of the transmission, which is normally under the front passenger side of your vehicle. The transmitter will have an electrical connector on its end. Remove this by squeezing and pulling the release tab.
Step 3: Use your wrench to remove the speedometer transmitter.
Step 4: Install your new speedometer transmitter. Use your wrench to ensure a snug fit.
Step 5: Attach the electrical connector to your new transmitter. Just push it into place until it clicks.
Step 6: Use your floor jack to raise your vehicle so you can remove the jack stands. Lower your vehicle to the ground.
These are general instructions. Refer to your owner manual for specific details that may require you to do the procedure differently.
