I have the Blue driver thing thats plugs into the computer and then be read via an app. Mine engine temp very rarely sees high 90's and only over 100 if 4wding, ive been towing a camper 100kph when it's been 47c outside with A/C on and by memory it got to 94 or 95. I wouldnt stress to much but its something to keep an eye on and maybe look into as i fancy 103's a little high considering your not towing and working it hard.
Check that your engine fan is turning slowly at Idle if not you may have troubles with the hydraulic switch. thee is a post on here somewhere to check to see if things are working correctly, could be radiator needing a good flush.
As for Trans temps i cant say for my Jeep as my reader dose not show trans temp, but with experience with other cars they seem to be right.
OH and cheers, i might look into a scan gauge 2 now so i can keep an eye on trans temp too, and makes it easier knowing the temp when your servicing the trans.
Where did you purchase yours from, and price if you dont mind me asking ?
