OBD Transmission Temp Devices?

[tacorancher]

Anyone have a recommendation for a simple to install OBD port transmission temp reader or blue tooth + app type of thing?

Related question. I keep seeing that the Tacoma transmission temps run high (see TFL toaster test) and yet the truck doesn’t throw codes and is meant to run high. Does anyone know why that is? Does Aisin use oil that can handle it? Or is it just cost cutting / shitty transmission cooler?

following, (other than the tran temp gauge in the gauge cluster, be curious what you come up with)

My big curiosity is whether toyota is cutting corners and betting people won’t need a transmission longer than 150K miles or toyota is smart and knows what they are doing — or if the temps don’t actually get very high for most people

lol this is exactly my thoughts, probably both tbh
