Finally, a solution to the 5 foot Promatic shifter cable.

Same route I took decade ago, still had problems... went 4 spd. no problems

Love the function of shifter itself and especially after some fine tuning of the cogs and centering spring.
The cable is definitely the weak point and this new cable should solve that.
I drove sticks for too many years and just got tired of it, especially for a daily driver.
