I did the drain/fill per ZF instructions, but the problem I had was while waiting for the fluid to get to operating temp, I couldn't manually shift the gears. I went through gears R-D several times, but when I tried to manually use my paddle shifters and manual S shifting, the gear kept going back to "M2"...I'm not sure if it's because of me having xHP flashed, or what.

Anyway, I ended up using about 4 liters, did the warm up + minimal shifting, checked again and only used an additional 2/3 liter, for a total of about 4 2/3 liter.

Do I need to flash back to the stock transmission firmware + attempt to re-do the warm-up procedure again, or is 4-5 liters normal?
