Hi, thanks for any advice re this.
Doing a cable change and now all cables have been removed from this shifter, it doesn't return to its neutral position, when pulled or attempting a ghost shift of the gears. Pulling on brake, or shifting, it doesn't return to its normal position. Right hand shifter is fine. I have drenched the inside with gt85, but to no avail. is this terminal ? Dont want to attempt to take it to pieces unless this is a simple job.
Thanks
