The valve body is easily accessible with the transmission oil pan removed. I inspected mine while servicing the transmission filter. I may go ahead with the level 10 or IPT valve body now that I have done the MTM TCU upgrade. If the transmission goes later, hopefully the valve body will survive and that will be one less cost during the rebuild. Of course while doing the transmission work, cleanliness is alway important. Another thought is that the Torque Converter is the weakest link in our transmissions and that the Audi part is improved and there are improved aftermarket ones out there. But the transmission obviously needs to be removed for this upgrade so at that time, I think a complete tranny rebuild (Stronger) would be in order.
