New guy here! This is my first post but I've been trolling the forums for quite a while now haha. 2017 2500 6.7 68RFE. I have questions about Revmax trans builds and why some of you decided to add specific parts (TC, valve body, flex plate, etc) and not just go with a "crate" 550, 700, 850 trans, other than the price. Are the crate transmission overkill? I drive my truck a couple times a week and pull my 11K lbs fifth wheel a couple times a month. Delete parts are on order (don't tell California) with plans on a compound turbo set up. I don't hot rod it around, will never pull a sled and have zero intentions of boosted launches. Just looking to make it a better tow vehicle without imploding my transmission. I appreciate the help in advance. Tons of knowledge on this board.
