My friend and I are fighting an issue w 2nd gear lock up in our 47re manual valve body's we built using a transgo tfod3 kit, we put a plug in the plate on his and flipped the lock up timing valve around backwards like we were advised, 3rd and od lock up works flawlessly, but when u flip the switch for lock up when your in 2nd gear it locks up for a split second and then shifts directly to 3rd but stays locked up, today we built my valve body using same transgo kit but jb welded the passage like most ppl do, and same exact issue, only thing we can come up with is the 2-3 shift spring is not strong enough to hold lock up on top of the 200psi of line pressure and causing it to shift into 2nd any ideas?
