I found the root cause of the problem, while my trans was apart today we found that the snapring that secures the drive sprocket to the input shaft had poped off causing the shaft to move back and forth wearing into the sleeve that the input shaft rides in, this caused low apply pressure to the TCC. The reason the snap ring poped off was the groove in the ZZP 4340 input shaft, that the ring rides in was machined incorectly it had a rounded upper lip causng it to pop off.
