Clunk When Shifting Into Second

Post by Dubstar77 » Tue Jul 08, 2014 12:35 pm

Hi, I have a 1976 type 2 which had full gearbox rebuild 3 years ago due to 3rd gear crunching on each shift. Everything was fine after the rebuild but now it has developed a frustrating clunk when shifting from 1st to 2nd and 3rd to 2nd. The clunk comes from the bottom of the gear shifter and doesn't sound like it is coming from the gearbox?

I have replaced the guide bush which the front shift rod runs through and noticed that the hole the guide bush fits into is slightly larger than the bush (there is some play). Could this be causing the clunk? Has anyone else had this? Is there anything that I could do to resolve this?

Any help would be appreciated

Paul

PS I have a Gene Berg shifter fitted?

Would you say that the clunk is emanating from the bottom of the Berg shifter? Glob some grease in the shift rod pocket where the shifter end goes. Let us know if that helps (there is a reason for that behavior).

Does the Berg shifter require a special stop plate? Or no stop plate? The only one I've seen required removal of the VW stop plate, but I know they make different models.

Stock VW shifters make a donk! in the shift rod pocket when you do a crisp shift. Bergs might do a clunk.
I wanted him to reply after greasing to see if it is now dampened.

I was thinking this was similar to the clunk I got with a "quick/short shift kit" a while back, where the ball was no longer positioned in the "pipe bowl" correctly. I MSPainted this diagram to show what I mean, but it might not be possible with the difference in late bay setup now that I think about it.

I'm looking at the gap between the shift ball and socket in the middle figure:

If the aftermarket shifter has a "lock-out" for reverse with a finger trigger, then it may say delete the factory stop plate. If so, the ball should be naturally a little deeper into the pocket.

If the factory stop plate is being used, the space in the pocket is for the reverse push-down to get the shoulder under the stop plate gate.
