Glad it worked for you. The vacuum cap is a good idea..:thumbsup:After reading this thread, I realized my truck had 40k on 6.5 qts of RP Syncromax. I was draining the fluid, which wasn't too bad at all, and came across this:
Lucky for me the Snap On guy was nearby an I was able to get the inverted torx bit. The part numbers and procedure were spot on! The only difference was my autozone didn't have the grommet, so I went with a vacuum line cap.
I poured in 7.5 qts of the Purple Drink and immediately noticed 5th was nearly silent and the DD had quieted down tremendously. Thanks again for the help!
