October 13, 2010Now that I am towing a 40 foot 5th wheeler with my 2007 5.9 Cummins with an automatic trans I think it is time to add some options. I am looking at an exhaut brake but not sure which one to get Banks, B&D or ? I am also looking at a trans pan with cooling fins and extra oil capacity. To finish it off I am looking at extra gauges for trans temp. exhaust temp and turbo boost. Any opinions on any or all would be appreciated. Your opinions are always welcome and helpfull.
