Ram 3500 shutters coming out of lock-up in or out of overdrive, and under a load. Trans has 35000 on rebuild with HD torque conv..This problem is more noticable with Edge Comp turned on. (llow level) Trans shop says there is no noticable problem. Governor pressure good, no oil contaminates or burning, no signs of slippage while monitoring. Shop manual says fluid break down may cause shutter, so fluid was changed (not flushed) and Lucas conditioner added. Problem improved slightly, but is not gone. Suspect clutch pack in trans is wearing, but thought someone might have other ideas.............Thanks in advance

 

What did they do to the valve body when they rebuilt the trans? Sonax Sure Cure was developed just to fix this problem. (along with a few others....) Might wanna look into getting one installed.
