Check the trans where the cross-shaft goes through for condition. I seem to remember some talk that the extra clutch-cover pressure can cause the shaft housing to crack/fail and/or the forks to fail so I'd keep an eye on it. All basic stuff to check before you get started anyway :wink: .

I agree with Lee here. Make sure you have one of the hd shafts in there. The forks are fully welded all the way around.

I have seen a trans with the forks folded back ("the clutch pedal suddenly got soft and I couldn't shift") and was told it was because of using a HD clutch cover (pressure plate [PP]). The discussion was a long time ago; it was when I was having a slipping clutch problem and had been given advice to convert to the 4-puck disc, which I did, but it was when were talking about which PP to use that this came up. I seem to remember that there was someone on STF that talked about clutch fork problems too... several years ago too. (I did a search but couldn't find the discussion directly but did find some discussion on shift forks in the trans forum. I'm thinking that the discussion may have been in the other VW site I used to go to which is now gone)

I've had early forks break right off of the shaft. Sucks.

Are late model ('74) trans any stronger? Should I just plan on getting the HD fork before I put in the new clutch setup?

The t/o bearing setup is better for sure. But I'd still put in the heavy shaft. Cheap insurance.

I think I will just wait till the end of this season and send the whole trans out. I know that with that new clutch and putting 20lbs of boost through the motor that something inside that thing will likely bust. Expensive Insurance :)

Sounds like you had other problems. Never had a cable or hook go bad after 5 years with a stg 3. I did eventually break the tube out of the tunnel, but welded it back in and had no other problems. I did use a long transmission arm though, that helped the foot pressure thing a lot.

long arm is a different thing. The parts back then may have been bad. This all happened in the late 80's. The last time I drove my bug.

Stock German pressure plate with a tilton dual disc. Still using mine daily for the past 15 years. Very streetable with a soft clutch pedal and holds very well.
