It’s designed to provide smooth shifting, protect against wear, and help with overall transmission efficiency. I’ve found that using the right fluid can make a significant difference in the way my car performs.

How to Choose the Right Dexron III

When I’m selecting Dexron III, I keep the following factors in mind:

  1. Brand: I usually opt for reputable brands that are known for their quality products. Some brands I trust include Valvoline, Mobil 1, and ACDelco. These brands have consistently delivered reliable transmission fluids.
  1. Type: There are different forms of Dexron III available, including synthetic and conventional. I prefer synthetic options for their superior performance and longer intervals between changes.
  1. Container Size: Depending on how much fluid I need, I choose between quart bottles or larger containers. It’s always a good idea to have a little extra on hand for future top-ups.

How to Check Your Transmission Fluid

Before I purchase Dexron III, I make sure to check my current transmission fluid level. Here’s how I do it:

  1. Warm Up the Engine: I start my engine and let it run for a few minutes to warm up the fluid.
  1. Locate the Dipstick: With the engine running, I find the transmission dipstick (if equipped) and pull it out to check the fluid level.

How to Change Your Transmission Fluid

If I decide it’s time to change my transmission fluid, here’s the process I follow:

  1. Gather Supplies: I make sure I have Dexron III fluid, a funnel, a new filter (if applicable), and a drain pan.
  1. Drain Old Fluid: I place the drain pan under the transmission pan and remove the drain plug to let the old fluid flow out.
  1. Replace Filter: If my vehicle has a filter, I replace it during this step.
  1. Add New Fluid: I carefully pour the new Dexron III fluid into the dipstick tube using a funnel, ensuring not to overfill.
  1. Check Level Again: After adding fluid, I check the level again to ensure it’s at the recommended mark.

Choosing the right Dexron III Transmission Fluid has made a noticeable difference in my vehicle’s performance.
