Default M6 transmission problem

What/where could make a M6 pop out of 6th gear?

The transmission was popping out of 6th gear, and while doing engine rebuild etc., i had the transmission fully rebuilt. Now after the rebuild, with all new parts, new syncros, billet keys, and it has the steel shift forks already, bronze shifter pads, it is still doing it.

The car has been back to the shop and the shifter adjusted, but that isnt curing the problem. What else could make it do this? Dont seem to have any other problems with it. It did the same with either a MGW shifter or the C6 shifter.

Everytime i speed up in sixth, the shifter starts to move to the neutral
position. Sometimes it stays in 6th and other times it pops out.

Need some ideas where to look from some good transmission guys.

The very first thing that you should do is INSPECT THE SHIFTER/SHIFT BOX! Make SURE that the shift box rubber BUSHINGS are not damaged or deteoriated and do a shift box alignment! Make SURE that the bolt that secures the shift rod to the shift box is properly connected and tightened!

Ive seen too many post lately where the SHOP SAID,, they check or aligned something and it wasnt done or done properly... I recommend rechecking the things mentioned in my post.. If it not that studd,, you have an internal 5/6th gear issue.
