    I have an '03 Suburban 2500, 6.0L 4x4. It has the 4l80e trans with a 2000 rpm stall conv. Does anyone else have this? Has anyone upgraded their converters? Just got back from camping pulling a 5000 lb camper. Rear end is 3.73 and 33" tires. Too high of a gear for OD on highway and going over mountains. I can't get the engine above 3000 rpm up the mount. I'd like to swap out the 3.73 for 4.56 gears. Any suggestions
