Anyone here installed a temp gauge on there transmission? I cant seem to locate much information on this. I see there is an Auto Trans idiot light on the dash so I am assuming I should be able to tap into the sending unit. Just wanted to see if anyone has done this on a Sequoia or Tundra? My sequoia has a trans cooler, I do tow a 6000 lb trailer so I wanted to see what the trans temp gets up to. Have never triggered the idiot light but want some better info on temp when towing.
