Whilst I'm inclined to agree with you to an extent....the regulator error code hasnt returned since having the fluid changed. Just the temperature one now remains and is intermittant.

I've been monitoring the transmission temperature with my Solus and found that as soon as it hits around 95deg C you can start to feel the slightly harsh 2-1 downshifts. Then they get more noticable after this. This takes around 40mins of normal urban driving before it gets to this temperature. It tends to sit at around 103-107degrees.

What temperatures do other owners tend to see?
