So is it different between e153 and s54 because the bracket I have is for an s54? The broken cable is the one that mounts in the cast part rather than in the pressed steel part? The forward backward selection rather than side to side
Quite apart from the bracket referred to, the forward/backward selection cable will always have much more flexing at the selector shaft than the side to side one anyway and is the one that generally breaks.
For longer cable life don't use solid brass, or ball race cable end bushes on that cable.
Only use either the OEM rubber mounted ones, or the rose joint type that reduce the flex.
I believe that solid poly ones are also available that are claimed to also reduce cable flex at the selector shaft.
