2011 lml, truck had Excalibur clutch kit and ratiotek valvebody kit installed 20k miles ago...random flare shifts and hard shifts ever since. Under wot the truck will throw a 0847 code.trans slips in 4th gear but no other codes other than 0847. As soon as trans slips the engine will defuel hard.. All other gears are fine other than weird shifts. Oil and filters are clean, no metal or excessive clutch material
LML P0847

Built it myself. The valvebody had rust and brown colored deposits in it, apparently had water damage at some point
