Common transmissions for that truck include:
* C6 (Cruise-O-Matic): This is a common automatic transmission. Its capacity is typically around 10-12 quarts. However, a complete fill and flush might require more.
* Toploader 4-speed manual: This is a manual transmission and requires different fluid (gear oil). The capacity varies depending on the condition and model variations.
To find the correct capacity:
1. Identify your transmission: Look for a tag on the transmission itself. This will have the transmission's identification code (e.g., C6, 4-speed). You might find it on the side of the transmission near the bell housing.
2. Check your owner's manual: If you have the original owner's manual, it should specify the transmission fluid capacity.
3. Consult a repair manual: A Haynes or Chilton repair manual for your specific year and model truck will give the correct capacity for your transmission.
4. Search online: Search online using your truck's year, make, model, and transmission type.
Without knowing the transmission type, I cannot give you a definitive answer. Providing the transmission type will allow for a precise answer.
