[Healeys] transmission

[John Soderling]

About six years ago my BN4 started to jump out of 3rd when coasting on a 
down grade.  Norm Nock's Tec Talk suggested it may be a weak spring behind 
the detent ball.  I took the side cover off the transmission and added two 
washers behind the spring and it cured the problem.
Vrooom vrooom,
