Hello again everyone, welcome to the my newest mk7 project!
I am attempting to get rid of this:
And replace it with this:
I'm assuming we can just Lop off the E-diff, slap a Wavetrac in and call it a day. EZ 2 hour install, right?
I've been messing around with transmissions a lot lately after breaking the driveshaft in my OEM unit early in December. I sourced a used replacement transmission out of a 2019 car, and bolted it up in place of the original.
Unfortunately, the new transmission seems to have developed a whine/gearbox noise in 3rd and 4th gear (Assuming it's a bad synchro) very quickly. The parts place will not allow me to return it, though they have refunded me some of the original purchase price. Two fluid flushes have not helped with the noise, but driveability is great! I'm just worried about how long it will last.
In preparation for this current transmission's death, I am working to rebuild my Og trans to be better than ever! I aim to install a Non-PP Wavetrac LSD as well as the longer axle and flange. This setup should allow the car to perform more predictably in canyon road/ track situations, as well as having added bonuses in weight savings and ease of maintenance. Now for the fun part:
Last night, I decided to open up my original 36,XXX mile transmission to visualize how this would all work. The only damage that I was able to locate was what we already knew about- The left output shaft had snapped and the bolt which holds it to the diff had stripped out. This transmission would need a new diff, or at least a spider gear to function properly again. The rest of the unit looked to be in great shape, and will be reused.
As far as fitting a Non-PP axle flange- I believe it will be doable as long as I swap the diff out along with it. In the photos below, you can see where the VAQ Diff bolts to the outer transmission case. There is an inner shaft as well as a set of grooves on the outer ring, which slot into the *open internal diff*.
