Hi folks,
I recently had a problem where if I put my Mk4 GTI in reverse it was actually in 1st gear. I was advised to adjust the shift linkages. In doing so I broke one of the shift end cable catch ->this part https://www.ecstuning.com/b-genuine-...nd/1j0711761b/ <-

I replaced the part and performed the shift linkage adjustment by following a youtube guide but I've just made it worse now.

Now reverse still = 1st
1st = 3rd
2nd = 4th I think
3rd 4th and 5th I think are correct.

I can get the car in reverse by pushing down on the golf club head looking thing that the shift linkage cables are connected to while another person moves the shifter into the reverse position.

Is it time for me to throw in the towel and accept defeat before I do any more harm?? Or is there something (anything) I can try before paying for a mechanic?

Thanks in advance
