I'm not sure on your issue, Freebusinesses. From my experience, the temp gauge will stay near middle even if things are getting too warm. In my case, I was finally able to solve my rough shifting issues (due to overly hot transmission fluid) mostly by fixing another issue: cleaning the throttle body...

Yes, the fan does come on with the AC. It's the only way that the fan seems to come on.

So I have this 2004 V70 2.5t with the AW55-50 with 150k miles which I have recently bought. It had rough shifting issues when getting up to temp, so I did multiple fluid flushes (along with a new radiator and flushes due to suspected cooling issues). Now where I stand is that the car runs and shifts...
