How To Install Short Shifter 240sx

So, you're looking to upgrade the throw of your 240sx's shifter? Installing a short shifter is a very popular modification, and for good reason. It offers a more direct and engaging driving experience by reducing the distance your hand needs to travel between gears. This article will guide you through the process of installing a short shifter in your 240sx. We'll cover everything from tools needed to step-by-step instructions. While this isn't the most complex job, it requires attention to detail and some mechanical aptitude. Let's get started!

Tools and Materials You'll Need

Before diving in, let's gather all the necessary tools and materials. Having everything on hand will make the process smoother and prevent frustrating interruptions.

New Short Shifter Kit (Make sure it's compatible with your 240sx model year. S13 and S14 have subtle differences)
Socket Set (Metric) – Specifically, you’ll need sizes around 10mm, 12mm, 14mm, and possibly 17mm. A deep socket set is helpful.
Wrench Set (Metric) – Same sizes as above.
Screwdrivers – Phillips head and flathead.
Pliers – Needle-nose and regular.
Hammer
Punch or Drift Pin
Penetrating Oil (like WD-40 or PB Blaster) – Crucial for loosening stubborn bolts.
Grease (Lithium or Synthetic) – For lubricating the shifter bushings and pivot points.
Jack and Jack Stands – Never work under a car supported only by a jack!
Wheel Chocks
Gloves
Safety Glasses
Shop Rags or Paper Towels
Optional: Impact Wrench – Can speed up the process, but not essential.
Optional: Magnetic Parts Tray – Keeps small parts organized.

Safety First!

Safety is paramount. Before you begin any work on your car, take these precautions:

Chock the rear wheels to prevent the car from rolling.
Engage the parking brake firmly.
Loosen the lug nuts on the front wheels before lifting the car. This makes removing the wheels easier once the car is in the air.
Jack up the front of the car using the designated jacking points. Consult your owner's manual if you are unsure where these are located.
Securely place jack stands under the frame rails. Ensure the jack stands are properly rated for the weight of your vehicle.
Lower the car onto the jack stands. Give the car a good shake to ensure it's stable.
Wear safety glasses to protect your eyes from debris.

Step-by-Step Installation Guide

Now that we've covered the preliminaries, let's get to the installation process.

Step 1: Accessing the Shifter

First, you need to gain access to the shifter assembly inside the car. This involves removing the center console.

Remove the shift knob. It usually unscrews counter-clockwise.
Remove the ashtray and any trim pieces surrounding the center console. These are usually held in place by clips or screws.
Locate and remove all screws or bolts holding the center console in place. These are typically found around the base of the console, near the seats, and sometimes under the armrest.
Carefully lift the center console up and over the shifter. You may need to disconnect any electrical connectors attached to it (e.g., for power windows or cigarette lighter).

With the center console removed, you should now see the rubber shifter boot.

Step 2: Removing the Shifter Boot and Retaining Ring

Remove the screws or clips holding the rubber shifter boot to the floor.
Carefully lift the boot up and over the shifter.
You will now see a retaining ring that holds the shifter in place. This ring usually requires a bit of persuasion to remove. There are usually small holes or tabs that you can use to pry it off. Use a flathead screwdriver or pliers to carefully work the ring loose. Be careful not to damage the shifter assembly or the surrounding area.

Step 3: Disconnecting the Shifter Linkage (Under the Car)

This is where you'll need to work under the car. Locate the shifter linkage where it connects to the transmission. This is a critical step, so pay close attention.

Locate the cotter pin or clip that secures the shifter linkage to the shift rod on the transmission.
Use pliers to remove the cotter pin or clip.
Apply penetrating oil to the linkage joint. Let it soak for a few minutes. This will help loosen any corrosion or rust.
Using a punch or drift pin and a hammer, carefully drive the pin out that connects the shifter linkage to the transmission shift rod. Be very careful not to damage the shift rod or the linkage itself. Support the linkage from behind to prevent bending.
Once the pin is removed, carefully disconnect the shifter linkage from the transmission shift rod.

Step 4: Removing the Old Shifter

Back inside the car, you can now remove the old shifter.

With the retaining ring removed in Step 2 and the linkage disconnected in Step 3, the shifter should now be free to be removed.
Pull the shifter straight up and out of the transmission tunnel.

Step 5: Installing the New Short Shifter

Now, it's time to install your new short shifter. This is generally a reversal of the removal process, but there are a few important things to keep in mind.

Compare the old shifter to the new short shifter. Make sure all the components are present and that the new shifter is indeed compatible with your car.
Apply a generous amount of grease to the bushings and pivot points of the new short shifter. This will ensure smooth operation and prevent premature wear.
Insert the new short shifter into the transmission tunnel. Make sure it seats properly.
Install the retaining ring to secure the shifter in place. Make sure it is properly seated and securely holds the shifter.

Step 6: Reconnecting the Shifter Linkage (Under the Car)

Head back under the car to reconnect the shifter linkage.

Align the shifter linkage with the transmission shift rod.
Insert the pin back through the linkage and shift rod.
Install a new cotter pin or clip to secure the pin in place. Bend the ends of the cotter pin to prevent it from falling out.
Double-check that the linkage is securely connected and that there is no excessive play.

Step 7: Reinstalling the Shifter Boot and Center Console

Now it's time to put everything back together inside the car.

Reinstall the rubber shifter boot. Secure it with the screws or clips you removed earlier.
Reconnect any electrical connectors to the center console.
Carefully lower the center console back into place.
Secure the center console with the screws or bolts you removed earlier.
Reinstall the ashtray and any trim pieces surrounding the center console.
Screw the shift knob back onto the shifter.

Step 8: Testing and Final Adjustments

Before you lower the car, test the shifter to make sure it's working properly.

Start the engine and let it idle.
Carefully shift through all the gears. Make sure the shifter moves smoothly and that the gears engage properly.
Check for any unusual noises or vibrations.
If you encounter any problems, double-check all the connections and adjustments.

Once you're satisfied that the shifter is working correctly, lower the car back down to the ground.

Remove the jack stands.
Lower the car carefully using the jack.
Tighten the lug nuts on the front wheels.
Remove the wheel chocks.

Important Considerations

Shifter Height: Some short shifters may change the overall height of the shifter. This is usually a matter of personal preference.
Notchy Shifting: Some short shifters can make the shifting feel a bit "notchier" than the stock shifter. This is normal and is due to the reduced throw.
Vibrations: Some short shifters may transmit more vibrations from the transmission to the shifter. This can be mitigated by using a high-quality shifter and properly lubricating the bushings.

Conclusion

Installing a short shifter is a rewarding upgrade that can significantly improve the driving experience of your 240sx. By following these steps and taking your time, you can successfully install a short shifter yourself. Remember to always prioritize safety and consult a professional mechanic if you're unsure about any part of the process. Happy shifting!
