Thts true billy. How much oil does the tranny and converter hold? I feel as if the tranny is fine, that converter is where the problem is. I amlost know it is. The tranny doesn't miss a beat but the converter sure does.
I would have at least 18-20 quarts on hand, I know with a double deep pan it's close to 5 gallons for a fluid change so that should at least get you going.
