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!
