You can run the trans as high as 220F all day long with NO ill effects. You can go as high as 250F for no more than a half hour at a time.
Check out pic -#2 the OP showed. It’s at 233 degrees engine temp when you convert that to F and listing the actual temp as a warning for being too hot so for sure something going on there that’s not right. These transmissions cool or warm from the engines coolant and looks like the engine is getting the trans hotter than normal. I agree, it’s not hurting the trans but not right and getting to the hotter side.220f is not really a "too high" temp for these though. I wouldn't worry too much at 220f.
Could it be possible that the shudders are staying closed , I would think the fans would come on and be on high.
The fanobecome high right and the coolnat temperature only rised for seconds and then when i drive its back to normal
Today i opened the hood and i found the coolant reservoir is low i add around 1 litres of water tomorrow i will send the car for check ! is it under warranty or not because i start to hate the car
