What others are asking Why is my transmission slipping?

The transmission in your truck has the updated 4L60 series with a heavier duty forward gears and thrust bearings so your transmission problem is most likely the torque converter or front pump failure.

Smell of coolant outside of car after running, no visable leak There two places I would recommend checking on this: In the trunk by the coolant cap there is a plastic shield.

Remove this and you should see a coolant air relief, or "burp" valve. Sometimes you will see dried coolant Car shakes when I slow down. The imbalance of rotating parts on a car, such as your wheel and tire assemblies, is a function of speed but also "positioning". Do not drive on these types of roads. This is not a malfunction. Restart the engine after driving onto a stable surface. Summer tire performance is substantially reduced in snow and ice. However, the sensors are subject to malfunction because of their location.

When the sensors fail or become contaminated with debris, the VDC light will come on. You will notice this can happen even when you are driving on smooth roads with no extra need for traction control. The VDC system is meant to create stability while traveling across slippery terrain.

However, the system can malfunction if the conditions are extreme. If you are driving across ice and snow, you might see the VDC light come on for a moment until traction is restored. However, as soon as the car begins driving normally again, the light should disappear. The steering rack is responsible for controlling the wheels based on the input from the steering wheel.

It is located on the body of the car as part of the steering system. The steering rack uses hydraulic fluid, which turns the wheels. If the rack fails or malfunctions, there might be trouble steering the vehicle, causing the VDC light to turn on.

The computer is responsible for taking the data from the sensors and translating it into action. As the wheels begin to slip, the ECU needs to cut power to the wheel for correction. However, the ECU is not foolproof and can go bad. To fix the VDC light, you must first figure out what the problem is. If the light is only illuminated because of the road you are on, it should go off when travel returns to normal.

In this case, no fix is required.
