Well, I was waiting for someone who's actually opened an MG transmission
to answer you, but if this is your third try and no one has...
In general a manual transmission stays in gear due to a detent on the
sliding rods. Your gearshift handle slides a rod back and forth.
Somewhere along the length of this rod is an area where a ball is pushed
against it by a spring. A notch is cut into the rod so that when you
move the shift lever to a gear, the ball is pushed into the notch, and
that causes the rod to not want to move anymore. Generally if your
transmission slips out of gear, it's because the spring against the ball
has grown weak, something has worn letting the ball and notch be not so
well aligned, the ball has deteriorated, the notch in the rod has worn
larger... The possibilities aren't endless, but I don't know of any fix
that will avoid removing the transmission and opening it up to find the
cause. If you've got enough wear that the detents are shot, you may as
well rebuild it. That won't be the only thing worn out in there, and
you don't want to pull the transmission twice.

'74 B - which stays right in gear. Although I don't recall which one.
I haven't checked in 6 months.

My friend has a 76 B that pops out of fourth gear once it warms,
although this does not seem to be a problem when it is cold. Does
anyone have any idea what could be wrong and how to fix it?
thanks in advance.
