thats great, you can try the retest procedure and see if it works, I have sort of given up on it - and I have read on other european forums that most people faced droning in the 722.6 boxes if the new 3134 ATF was used which was remedied by going back to the original fill ATF 3403 - which is not available in the USA anymore.
