I was just on the website, ordered the kit for sampling and noticed that they check transmissions too. So I called and asked if they also do the PTU oil and they said yes. So I asked for additional kits to do all of them. I was just curious as to how many of us have had them check transmission and or PTU and what were the results if any. Since I now have more then one high performance vehicle I plan on making this part of my maintenance schedule.
