Make sure the van is level including side to side when checking fluid
levels. If much above the top mark warm drain some off. The Audi cooler does
not make that much difference. Glad it all worked for you. Now that really
wasn't that bad a job, was it?

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!
