2nd rebuilt torque converter came Friday evening... and we just took a maiden voyage... Seems great! Trans was completely empty and we filled with 2.5 quarts dexron... started up in shop, then 3.5 US quarts of Dexron, but after an 8 mile warm up it, it reads a tad high on the stick??? Bentley states "6.4 US quarts total capacity, plus we have the larger Audi trans cooler...Time will tell (especially after a few days of beautiful Pennsylvania's mountains) THANK YOU Dennis Haynes for all the text assistance!
