Recently I started having shifting problems with my truck so i decided to buy a whole new valve body for it after talking to several people. After installation truck immedietly cranked right up and threw me P0740,P0743, P0750, P0753, P0755, and P0758? I am stumped and have absolutely no clue on what to do next. There are no videos on youtube and no good answers on the internet that I can find. Any help or advice would be greatly appreciated! Also while I replacing the valve body I went ahead and changed the fluid and filter.
