MG MG Y Type - Gearbox

I had my gear box rebuilt 8-9 years ago because it would not stay in first gear and became more and more difficult to hold it in first. Got as I recall a new cluster gear and new first and reverse gears and all the bearings and bushings were renewed.
Never been really happy with the result. In first gear the leaver would move so that it almost disengaged unless you held it. Recently it has started to disengage so am back to my original problem.
Can't remember what it cost for the rebuild but it wasn't cheap.
Anyone else had this problem? Is there a simple solution that I am missing?
The Y, TD/TF gearbox has a poor reputation. A friend with a TD and similar but more extensive problems has just insalled a Sierra 5 speed and raves about its performance. Has anyone installed one in a Y? Can it be done? What are the potential pitfalls? It would probably not be that much more expensive than rebuilding the existing box. Terry

Have you availed yourself of a copy of Neil Cairn's book on the XPAG Gearbox? I dont know if it would help as I dont have a copy - but I do know it is a good book! See the Book Review page.

It is possible to fit the Ford gearbox: http://www.mgcars.org.uk/mgccy/pdf/yb5speed.pdf

Thanks Willem, hope to make Silverstone this June so will look into it as a winter 2008 project. Terry

Your problem sound like the locking bolts for the selectors are loose. They have to be wrie-locked, it is possible the people who rebuilt it failed to do this, and vibration has loosened them. This is all in the gearbox book Paul mentions. You can remove the top cover from the gear box without removing the gearbox itself, just the floor cover. All the locking bolts are easily seen, they have square headed bolts.
