[QUOTE=bhennrich;1065638]Well... I did the dreaded 6HP26X trans service and Liqui Molly engine flush. F**K this B**L S**T is all I can say right now! I have had the parts and fluid sitting in my garage since September and finally had a buddy around to help this evening. I had a surging / slacking issue in fifth gear ONLY and after talking to ZF I went forward with this fluid change. The only redemption to my evening was that my 4 1/2 year old daughter wanted to "help" and "learn how to fix our cars." By the way do NOT go with the vaico filter for the trans... It kept falling out... I had to re-use the existing ZF filter seal to keep it from falling back out of the transmission. And the Febi trans pan gasket does not fit... I will be calling ECS in the morning and might freak out on them a bit... Updates will follow when I have them.[/QUOTE
