Tools You'll Need:
* New kick-down cable (ensure it's the correct one for your specific model year and engine)
* Socket wrench set (metric)
* Screwdrivers (Phillips and flathead)
* Pliers (needle-nose are helpful)
* Possibly a pry bar (for stubborn connections)
* Shop rags or towels
* Possibly a flashlight
Procedure:
1. Disconnect the Battery: This is crucial for safety to prevent accidental shorts or electrical damage. Disconnect the negative (-) terminal first.
2. Locate the Kick-Down Cable: The cable connects the throttle linkage to the transmission. It's usually located near the throttle body and runs towards the transmission. You'll need to locate both ends – the throttle body end and the transmission end.
3. Disconnect the Cable at the Transmission: This is often the more challenging part. There's usually a clamp or bracket holding the cable to the transmission. You might need pliers or a small screwdriver to release the clamp. Take note of how the cable is routed and connected. Take pictures if you need help remembering.
4. Disconnect the Cable at the Throttle Body: This end is usually simpler to access. There may be a clip or a bolt securing the cable. Again, take note of how it's connected.
5. Install the New Cable: Carefully reverse the steps from disconnection. Insert the new cable into the transmission bracket, making sure it's seated properly and the clamp is secure. Then connect the other end to the throttle body, ensuring it's properly adjusted.
6. Adjust the Cable: This is critical for proper shifting. There's usually an adjustment mechanism on either end of the cable (or sometimes a screw adjustment on the transmission end). You'll need to consult your vehicle's repair manual for the specific adjustment procedure. Incorrect adjustment can lead to poor shifting or even transmission damage. This often involves slowly opening the throttle and observing transmission shifting. Adjust until smooth and positive shifts are achieved across the RPM range.
7. Reconnect the Battery: Reconnect the positive (+) terminal and then the negative (-) terminal.
8. Test Drive: Test drive the vehicle to ensure the kick-down is functioning correctly. Pay close attention to the shifts. If the shifts are rough, you'll likely need to re-adjust the cable.
Important Considerations:
* Repair Manual: Obtaining a repair manual specific to your 1999 Chevy Tracker 2.0L 4x4 is highly recommended. It will have detailed diagrams and instructions for the proper procedure and adjustment.
* Transmission Damage: If the kick-down cable was broken due to other transmission issues, replacing the cable alone may not fix the problem. The transmission itself might require attention.
* Safety: Always prioritize safety. Work in a well-lit and ventilated area. Use jack stands to support the vehicle properly if you need to work underneath.
Remember, this is a general guide. The exact procedure might vary slightly depending on your specific vehicle. If you have any doubts, seek professional help from a qualified mechanic. Improper installation could damage your transmission.
