Help!?! New Clutch And Now Shifting Issues!

[Btrainfiveoh]

Hey guys! I'm in need of help... I have an 06 GT. It's had a hurst comp shifter since before me... When I had gotten it, shifting was kind of difficult, especially wide open throttle 1st-2nd. Anyway, I changed the transmission oil to Mobil 1 synthetic atf .. Definitely made it ALOT smoother, although I'd still get that slight delay at WOT 1-2 shift but I got used to it. Anyway clutch started slipping was the stock clutch, car has 192,000 kms on it so that's about 110,000miles roughly. Anyway this past thursday(a week ago) I got a McLeod super street pro clutch kit(which comes with a shim for the slave), I got a replacement slave cyl, pilot bearing, and rear main seal. Got it all done from a shop. I noticed when I got in the car to pick it up it was in 1st gear, I started the car and noticed as I had pressed the clutch before starting the pedal was way too soft(most likely air in the line). Anyway the car wouldn't come out of first. I had to turn it off and then pull it out of first. Anyways they said it's probably a little air in the line which will come out after driving a couple days. Well, I even bled the line(vacuum pump on master cylinder operation) the clutch pedal is fine feeling. Solid. But even now, when I'm sitting at the lights in neutral, I press the clutch to put it in first, it won't go into gear. Once I put it in third first, then it'll slide into 1st no problem. And while driving there's really no issues... Shifts fine. But why won't it go into first now? Once it warms up it starts going into 1st but still it requires some push. Not smooth. Did the new clutch and what not cause the hurst shifter to amplify it's issues?(I know people complain of hurst). And yes the flywheel was machined when the clutch was done. They will be taking a look at it on Saturday but I'm trying to figure out if any of you could have a guess as to what it could be. They didn't remove transmission oil or nothing, I'm not sure if they needed to disconnect the shifter, and if they did, maybe they reconnected it wrong or too tight? I'm lost right now as to what it could be, but it's very annoying after spending so much money it's not right in my eyes. Any help would be greatly appreciated! Also since the clutch it has 240 kms on it, so that's about 140 miles I guess. (Roughly) ... I was told 500 miles/700 kms for a break in period.

The synchronizers in the transmission are probably due for replacement.

The synchronizers in the transmission are probably due for replacement.

If it were the synchros... Wouldn't they give an issue all the time, especially at higher rpm? And also, why would it just occur after the new clutch job....?

I don't think its the synchros. with the car stopped and the clutch pedal depressed, nothing in the transmission should be rotating. It sounds like the clutch isn't full disengaging. You brought it back to the shop and they told you to let it break in ?

Agree.

That's right, they said let it break in. But I have an appointment on Saturday at the shop. What's weird is when the car really warms up. It does get a bit easier/better. Still not 100% in my opinion but it does get a bit better. Also I noticed yesterday whoever installed the hurst shifter installed it incorrectly. The offset is to the wrong side, I don't know how much of a difference that makes

Also, just curious, with the whole clutch disengaging issue, why would it easily go into 3rd then 1st(when at a stop) but going straight to 1st it won't go. The more I wonder the more I think maybe it's a shifter issue? Maybe the fact that it's installed wrong(offset side facing wrong direction) although apparently I've heard the shifter will work both ways, and maybe they tightened the bolt too much? I've heard to not tighten it more than 15lbs ... I just can't understand what the issue could be. Once it's in gear at a stand still it definitely has no problem coming out of gear or shifting through gears with the clutch pressed and at a stand still. It's the initial time you try hitting 1st gear.

I'd be looking at the syncro rings for 1st gear, and the clutch freeplay. Most clutches with a hydraulic master/slave have adjustment in the rod to throwout fork. if the clutch has too much freeplay, it will not disengage completely. If the 1st gear syncro is worn (you complain of this as a preexisting issue) then the gearset won't be stalled when the clutch is depressed and the shifter is pushed to 1st gear position. That clutch disc drag is a bitch,and must be minimized. Assuming that the shop knew what they were doing,and torqued the new pressure plate correctly, then a simple operating rod adjustment should correct the problem, or a set of syncro rings.

^ It's not a preexisting issue.He said when he bought the car it was difficult to shift under wide open throttle, which he corrected by replacing the fluid. After the clutch replacement he has no issues shifting while driving like he had before. The problem he is having now is that he cannot shift into 1st when stationary, unless he shifts it into another forward gear then shifts into 1st. Sounds like a clutch disengagement issue to me.

 

[Btrainfiveoh]

Exactly. Svtpilot. You nailed it. So on Saturday at the appointment the tech said the one thing he's worried about is the flywheel. The fact that it was machined, he doesn't know how much material was taken off, because the machine shop even said that the flywheel was in bad shape and they had to take quite a bit off. It's deff not disengaging fully. It feels like it's even worse now, I'll be calling the shop today And seeing when they have time to drop the tranny again.

Hey all, I know a lot of people don't post when the issue gets resolved. Just wanted to let everyone know, the shop took it all apart. Ordered a new super street McLeod clutch kit... Turns out there's a manufacture defect/issue. The pressure plate springs sat a quarter inch too short, hence the disengagement issues. And furthermore who knows what else issues that kit had with it. Just picked up the car and so far so good. Right now the pedal disengages closer to the floor, but shifts super easy, and this clutch grabs very strong! The pedal is definitely firmer than stock(the first time I picked it up the pedal was light) so I'm hoping that was the end of my issues. This weekend I'm hoping to be able to really put the miles on it and see how it feels. Thanks all for the help!

^ Glad to hear it ! And thanks for posting the fix.

Loving the hurst shifter now too, shifts very precise and effortlessly
