the reason the marv booth guy recommended using some motor oil with ATF was heat related. It would still lubricate at a higher temps when ATF was useless as a lubricant. Seems like he said 16 to 32 oz. depending on how hard the transmission was used. I have put 16 oz. in everything for over 20 years.
