I've had my 66 TR6 since 2006, when I got it gear changes were hit and miss to say the least. I opened up the box and found one of the selector rollers laying in the bottom of the box, the previous owner said it must have been like that since 87 when he last put it together. Refitted the roller and the box was much improved, however when opening it up in second it would just touch 5000 rpm and jump out of gear leaving me stirring the box for anything I could find. All the rest of the gears were fine. Recently I got around to replacing the selector forks and finally cured the problem with second gear. Now if I don't hold upward pressure on the lever it will jump out of 4th gear. Any thoughts?

What did the shifting fork peg and the camplate groove look like after 33 years of the peg moving the camplate?

When a gearbox is jumping out of gear I always ask myself whether I'm sure the box ever gets fully into the gear that's jumping out.

I'm posting two images to help visualize the problem:

The shifting mechanism:

The position of the camplate and the inner quadrant when the gearbox is in 4th gear:
