Hello again, it's time for a filter and fluid change for my 1978 C4 auto. The manual calls for type "F", but I'd like to try a synthetic.
Price is not an issue, I just want the "best" in terms of smoothness, and the fact this is an old transmission and could probably use a healthy dose of additives.
Is a flush necessary? I plan to drop the pan.
