Recently had a JWT clutch and flyhweel done. SS line, chromoly pivot ball, new slave cylinder(advanced part). Torque solution STshifter.

the shifter was installed a while after the clutch job. i Notice the shifts are a lot harder to get in gear but quicker. I actually took my car to the track for the first time this year to see how she launches. Here lies the problem. She launches nice, and i can powershift into 2nd, well now im not trying, and then once i go to put in third, fast, it wont go in and i have to go in 4th. I CAN NOT shift this car fast anymore. I was thinking:

A. Bad slave cylinder because i cheaped out with some ******** Advance part, and the new clutch is too much.
B. short throw shifter is misaligned.

Thats the only two things i can come up with, I am going to try and re bleed this weekend and go over the new shifter. but any help from some Vets would be appreciated. I was very bummed tonight that I couldnt shifter fast.

After leaving the track, I forgot to mention, she seems to hesitate taking off from a stop or a slow roll. which makes me lean more towards the clutch parts...slave/master slave.

did you do the proper break in of the clutch?

Did you align the shifter correctly? Is it bled all the way?

I had some similar problems after my JWT clutch flywheel install. I had already upgraded the MC due to pedal drop a couple years prior. When I changed out the clutch and flywheel, I changed the slave as well. I also changed the fluid in the transmission and rear diff. When I was having some issues with hard shifts and getting it into gear, I ended bleeding everything again and it shifted much smoother. Following the break-in period, you'll notice it being less stiff as well. I would recommend bleeding everything again for good measure to eliminate the possibility of air in the lines. If you still have the OEM master, bleeding can be a PITA.

Thanks guys. Makes sense to do another bleed after i broke in everything. And yes to the above comment about clutch break in

Im going to flush the fluid this weekend and out some better fluid in it. and check my shifter bracket by the spring etc... Thanks a bunch guys.

So I re bled the clutch and took a look at my shifter. couldnt align it this weekend..
The shifter still makes a loud vibrating sound but only in 2nd, 4th, and 6th. Which leads me to believe its hitting something low on the underside by the tranny and not a tranny or clutch problem. But I went to the airstrip this weekend and launched once, not hard, shifted aggressive but not HARD. noticed it hesitated from a stop after launchuing...This now leads me to believe its definitely a shitty slave cylinder. gonna be going with an OEM slave and Wilwood setup soon. Eliminate all this ********!
