How much transmission fluid do you need to replace the and filter on a 1993 Chevy G20 van?

You won't find a single definitive answer for the amount of transmission fluid needed for a 1993 Chevy G20 van's transmission fluid and filter change. The amount varies depending on the *specific* transmission your van has (different models used different transmissions). Also, some fluid will inevitably remain in the torque converter.

To find the correct amount:

1. Identify your transmission: Look for a tag on the transmission itself (often near the bell housing) or check your owner's manual. Knowing the transmission type (e.g., TH350, 4L60E, 700R4) is crucial.

2. Consult a repair manual: A Haynes or Chilton repair manual specific to your 1993 Chevy G20 van will give you the precise capacity for your transmission. This is the most reliable source. These manuals often list capacity with and without filter changes.

3. Check online forums: Search online forums dedicated to Chevy G20 vans or the specific transmission you've identified. Other owners might have posted the amount they used. However, treat this information as a guide, not a definitive number.

General Approach (Don't rely on this as the precise amount):

Plan on needing at least 4-6 quarts. You'll likely need more than the stated capacity because you're not completely draining the transmission. It's better to have extra than to run short. You can always return unused fluid. Buy in quarts so you have flexibility.

Important Note: Always use the type of transmission fluid specified in your owner's manual. Using the wrong fluid can severely damage your transmission. Consider also purchasing a new transmission pan gasket while you're at it.
