hey guys,
like in my other post mentioned, i have a 2008 burb with the tow package, which gives me a chance to display my tranni temperature. but now i need to know when a bad tranni temp starts. at what temperature does my tranni get hot? whats the best to do if it gets hot? thanks...

 

Once you reach 200 F you need to be mindful, short periods of 220+ are ok if they are short i.e. pulling up a hill... I am no expert on the subject, but this is what I have gleaned from the forum...
Hopefully with the external cooler you should rarely see high temps...
