This New Valve From GM is Said To FIX The Valve Body Issues - p0747

GM has just released a new bulletin for the 10-speed automatic transmissions (10L80/90 and 10L1000) that changes how we repair DTC P0747. Up until now, the fix was a complete valve body replacement — often with an updated Gen 3 unit. With this bulletin, GM is no longer sending out valve bodies. Instead, the repair is now targeted: replace the feed limit valve, the stronger spring, and the updated spacer plate. In this video, I’ll walk you through what’s changed, show the updated GM parts, and explain what this means for technicians and truck owners. 📄 Full details, including part numbers and labor times, are available here: https://www.duramaxnews.com duramaxnews.com/post/breaking-gm-issues-new-valve-body-repair-for-p0747-on-10-speed-10l80-10l90
