^Ah yes right.
I had an HDX in my old GT. Pedal chattered and vibrated like crazy. Put in a stock Valeo/Sachs unit and all was well.
Does the vibration of the pedal increase/decrease with heat in the clutch/drivetrain?
It appears to increase around 2k rpms, at idle it is barely even noticeable. I'm starting to wonder if its possibly just a bad tranny mount, thats the one thing I didn't replace while it was out.
I also inspected the rear differential today, my seal I made on the diff cover is holding fine. Its leaking a little bit from where the driveshaft attaches to the diff. Its always leaked from this location since I bought the car, so I'm not worried about it honestly. I filled it a little over a year ago when I bought the car, and it was still at a safe level when I popped the diff cover off to re-seal it, so it appears to just be a very minimal, slow leak. If I ever decide to re-gear from 4.10s to 3.73s or even 3.55s possibly I will obviously have this fixed at that point. But I probably won't bother.
I still need to take a look through the inspection cover to see if I can see anything that would explain the clutch pedal vibration I am experiencing, re-seal my thermostat housing to fix a small coolant leak, and other than that it is running fine.
Other than those little issues, my plan is just to drive it and enjoy it for a while, get some enjoyment out of this built transmission I spent so much $$$ on, but eventually I am gonna have this car up for sale. I love this car, but I have other priorities right now besides going fast. I'm not the kind of guy to ever keep a car more than a few years anyway. I'm looking at a base c5 corvette, or maybe a 2002-2007ish dodge ram w/hemi, not in a rush to do anything, but probably this will happen in the next 3-6 months. I want to get all the bugs out before I sell it, because I won't be misleading anyone that is interested in buying it. Not sure how much I can get for this car considering the bad paint, but I spent 8k on the car, and have put like 4-5k into it since then. I will probably ask like 9.5k lol, its the nature of modding a car.
