Im going to leave my stock tire size and leave the stock 3:73 gears and just not stress about the rpm. I got my transmission gauge hooked up I ended up going with a autometer cobalt series transmission gauge and bought a mpx performance billet aluminum gauge pod so I didnt have to drill holes anywhere looks really good and works great. What kind of transmission temps do you guys see when not towing and when towing? Its been cold here but just normal driving around my trans temps haven't gone above 138 degrees which seems like a good thing.
