On street it stay 160-165 dont matter how hot it is outside. I recommend a thermostat if you are going to bypass the stock heat exchanger.
Hi , I located my transmission cooler in front of the grills. This induces the trans temperature always below 40 Celsius in winter. It hardly reaches to 60 in summer despite hard drive. No issues so far. Will it be a issue in long term ?
