If I put a supercharger kit on my truck I want to upgrade the trans. While the 4L80e is a stout unit, mine has 258k on the original in a 7000 pound truck. Even just 50% more power puts me over the 440 lb-ft input limit is 4L80e is rated at. If I wanted to upgrade the transmission without rebuilding it, what upgrades do y'all recommend? I know there are quite a few threads, but most talk about rebuilding. Thanks in advance!
