Break points/weak points that need special attenton on a rebuild are: front/rear One way sprags, OD planetary, reverse planetary, governor, center support, OD drum, and rear case washer/reverse race (All HARD PARTS). Also, I respectfully ask: How do you know it was a new valve body? Not to sound mean, but cleaned up and from underneath they ALL look new. I hope you get good service from it, and you well may - or, depending on what they started with - you might. If that is what they did, and all of what they did, to the 206,000 mile A4LD from my Explorer, (if IT were the core) would that be enough for you ? I'll shut up. Certainly no offense meant.
