How much transmission fluid does a 1970 ford f250 automatic hold?

The capacity of the transmission fluid in a 1970 Ford F250 automatic depends on the *specific* transmission it has. Ford used several different automatic transmissions in their trucks during that year. There's no single answer.

To find out how much your specific truck holds, you need to:

1. Identify your transmission: Look for a tag on the transmission itself, or consult your owner's manual (if you have it). The tag or manual will usually specify the transmission type (e.g., C6, FMX, etc.).

2. Consult a repair manual or online resource: Once you know the transmission type, search online (e.g., using Google or a forum dedicated to classic Ford trucks) or consult a repair manual specific to your year and model Ford F250. These resources will give you the correct fluid capacity for your particular transmission, including whether it's a fill with the engine running or off capacity.

Without knowing the transmission type, any capacity figure would be a guess and potentially inaccurate. Getting the wrong amount of fluid can seriously damage your transmission.
