Hi,
The 17 quarts is if the entire system is drained, cooler, torque converter, valve body, and so on. What you installed sounds accurate or close to it.
With your part number above, I was able to determine the transmission is an E40D transmission. The vehicle speed sensor is on the tail housing (driver's side). See pic below. Note in the picture there is no speed sensor installed.
In that location, you can have a speed sensor, a plastic plug, or the bolt hole where the sensor or plug bolt-on can be missing. If it is missing, the VSS will be on the differential.
Let me know if this helps.
Take care,
Joe
