1968notch
Too many projects, not enough time/$$$
Hi all,
I did a 904 swap on my 1968 Notchback. Swapped due to no reverse and no 3rd issue. The only part in common with 3rd and reverse is the front clutch. After the swap, i noticed the rev between 2nd and third just like the previous 904 prior to ultimate failure of 3rd altogether and eventually reverse. Here's the thing though, in both situations, when it did hook up in reverse, I could smoke the tires with either tranny.
The first issue is that the replacement failed much quicker than the the original from the point of "extra rev between 2nd and 3rd" (running in drive natural shifts) to ultimate total failure , The second issue is WTF over?
This isn't a clutch friction material problem, it's a front clutch "apply" problem. Meaning that the fluid required to press the clutch pak together (the steels and friction material) isn't there. Like I said, when it does hook up in reverse, it fry's the tires. That is NOT a friction material problem, it's an apply problem.
My question is, the fluid that is sold today and what I used (dex-merc) which states dex3 compatible is causing this issue or is it just bad luck on the apply O-ring?
I will provide tranny #'s later for which one to rebuild based on 1st gear ratios. Running a 7.25 @ 2.73 rear so the lower the better. Rear end swap and a modded TQ (excellent carb rebuild by me, as in scary fast through first and second) 4bbl teener to 340 swap in progress.
Thanks,
Paul.
