im new to this forum stuff so dont go crazy if i have got this post in the wrong place!!

im 18year old and very mechanicly minded, worked on historic rally cars, modern track cars and every day road cars, so am not affraid to get stuck in.
my mum and dad bought a morris minor traveler about 3 years ago, when they bought it they found that it was slipping out of first gear, now having done about 500 miles a year, first does no longer exist and pulling off in second seams to be the way forward

MY BIG QUESTION IS, IS THERE A COMMON PROBLEM THAT CAN BE FIXED WITH THEM??
any help will be much appriciated
