V6 mc price shipped to 14450. Hoping this is my cure to a 1-2 shift crunch

You guys have a hydraulic clutch system fluid of choice? I figure standard brake fluid should do, but if there is a magic bullet that resists the abuse of the heat and clutch dust better I'm all for it.
As promised, I'm reporting back after my install. The install is relatively straight forward. Definitely having the right angle attachment for the drill to run the self-tapping screws (#10x3/4) is extremely helpful when mounting the remote reservoir. And get your favorite contortionist friend to handle the under-dash work! Also, you don't get a lot of bleeds on that remote reservoir, so there is definitely some up/down on the lift - bleed it 2-3x then top it off, repeat a few times.

Got it bled good and got a good feeling pedal - maybe a touch lighter feel and touch higher engagement, but really not much of a different feel from stock. Drives normal under cruising circumstances. For the redline 6500rpm 1-2 and 2-3 shifts I would say I have definite improvement - I can snap those shifts off quicker than before. I came back from the test drive very happy indeed. However - if I'm super aggressive in pulling that shifter, I'll still grind the 1-2. I have no low speed grinds, not even cold - and the car downshifts just fine - I don't think I have a synchro issue.

I don't hold the master cylinder responsible here - I definitely got the improvement I was expecting. I believe that the Hurst (aftermarket with the 44% reduction) with it's major throw reduction is just capable of such incredibly fast shifts that its too easy to be getting to 2nd before the clutch is fully released. So I guess I can continue to drive around it (which is definitely possible) or I can start looking for another short throw option. I'm gonna post a thread specifically about the Hurst short throw and the 1-2 grind to see what kind of input the forum can give me - I appreciate any insight you guys can offer on the question to make this car bang gears like it should.

I recommend bleeding the system while the main brake reservoir is still hooked up so you have more fluid to work with, then you can connect your GTO reservoir and block off the main reservoir.

We also recommend the MGW shifter instead of the Hurst.

That's funny - when we were all finished I said to my buddy "we should have bleed that thing from the brake master."

I'm definitely looking into my options for short throws. Again - nobody mis-read me, the Ideal Garage clutch master cylinder is worth the money - I've got a quicker shift than I had before. Maybe I'm splitting hairs, or maybe this Hurst is screwing with my head, but I really would like to be able to rip of shifts without having to constantly remind myself "clutch, then shift" - I've had a bunch of stick cars that I raced and never had that problem till this car.

Just to aid and further the discussion, here is some before/after video. First video is the drag strip last fall on the stock master cylinder. That was about the limit of my shift speed without inducing a grind on the 1-2 and a crunch on the 2-3. Second part is today on the way home from lunch after having the Ideal Garage Master Cylinder in for a few days. The 1-2 is a little faster and again is pretty much at the limit for speed before grind. The 2-3 is definitely faster, and has no crunch at all on maximum effort, which that nearly was.

Am I expecting too much? I've never had to think about shifting so much, and it robs me of a little joy, not to mention the gross feeling of taking a little more life off the dogs and gears every time I grind that 1-2.

Back again with an update. I was able to obtain a stock SS shifter to try out. Swapped it out last night. That Hurst Billet Plus 2 was REALLY stuck in there, but we got it out with some persuasion. Stock shifter went in find. Much less play side to side than the Hurst, and perfectly silent. And the most important part - it'll rip a 1-2 shift off great now. No grinds. I ripped at least 25 hard/fast 1-2 shifts last night and didn't grind a single one. I may have felt a nibble just one, but nothing on the rest of them.

I'm thrilled - I can finally drive this thing like it always should have been. I can go back to driving "spinal cord" vesus having to be careful and deliberate on every shift. The stock shifter definitely has a longer throw, and weaker centering action - but not to the point of being an issue. My 2-3 shifts were quick and solid like always. And the shift effort is greatly reduced, no more notchy-ness or fighting to push into a gear.

The bushing on my Hurst were definitely pretty worn - I had lots of left-right play and just a tiny bit of forward/backward play. My theory is that due to the worn bushings I was getting an "incomplete" or "weak" push against the syncro. As guys probably know a syncro relies on pressure to push those clutch packs together and speed up/slow down the target gear. With a weaker push the syncro couldn't do the work it needed, nor could the gear pull firmly into place - and hence the grind.

I still contend that the Ideal Garage master cylinder was helpful in speeding up my shifts and reducing the grind - I had a noticable improvement with it's installation - and probably would still have a grind even with the stock shifter without it. But you Hurst Billet Pro 2 plus guys that are grinding - maybe consider trying your stock shifter out to see if that helps.

Has anyone ever had this cure a second gear lock out for a high rpm shift? Very randomly I'll miss the shift to second, last time it felt like it was locked out. Not sure if it's a clutch issue or hydraulic issue and I haven't had it diagnosed at a shop yet since it happens so rarely
