Anyone having overheating problems?

[FordFan86]

With the weather currently above 40 degrees here and I'm sure in other places around Ausrtalia I was wondering if anyone has had any problems thus far?
Climate control on in mine (NC V8, set at 16 degree) and cruising along at 80k it was sitting up halfway and occasionally sinking down a bit further/cooler. So I'm pretty happy with that....
Also, going around 50/60k it will drop into LHM and stay there till the speed is increased, this is normal to try and cool the trans and engine (as per owners manual). Any one else experiencing this, and would fitting a larger trans cooler prevent this happening?
