Default modified C5 shifting problems

Hi all, long time lurker first time poster.

99 C5 D1 procharger, McLeod twin disk, transzilla. Won't go into reverse with the car running but goes in fine when off. Shifter will go all the way over to the right but won't go forward into gear. Also shifts hard into 1 and 2 but will go. Changed the fluid out tonight for the clutch and made no difference. Where do I go next? Thanks

Michael

The clutch is not fully disengaging. Have you tried bleeding the clutch hydraulic system?

What clutch do you have?? How old is it?

Do you have a stock OEM master cylinder?

If you put the car in 1st gear, clutch fully depressed and rev the engine to 4000-5000 rpm, does the car start to roll??

If you jack up the rear, with the engine running and car in gear with the clutch depressed, do the rear wheels spin?

Quick test to see if the clutch is disengaging.

I ordered a TICK Master just to eliminate this issue. It has more depressed fluid volume and is adjustable.

It is the stock MC. I was looking at the TICK but hoping the stock one would be OK. You are confirming what I have been thinking. I have to shut the car off to get it into reverse, when i restart it in reverse the car starts to roll in reverse. Thanks for the input.

installed the tick MC and no change. It seems to be adjusted correctly, peddle is firmer but is still not fully disengaging. My next step is to call Tick and confirm and then to call McLeod and get their thoughts, any other suggestions?

If the Tick master didn't cure the problem then you need to start thinking about changing the clutch. There have been quite a few negative reports on here about McLeod clutches. Pit-man has had hell with his!

that's what I'm afraid of. Ate up a centerforce last year with few miles so tried a twin disk and has never worked right, just not looking forward to putting in another clutch. What brand has worked well for others with forced induction?

What shifter do you have? Stock C5 shifter? my buddy had a simmilar issue with his and his aftermarket shifter was jacked up (dunno how) but he put a stock shifter and he also had a new OEM Master cyl and aftermarket clutch that wouldnt shift without grinding and had shifting issues in a couple gears that corvette connection added shims/spacers to the clutch (dunno where exactly, its been a while and my buddy is not mechanically inclined to accuratly describe it to me) and fixed his shifting issues. shifted very well after word.

That's what I'd do. As another poster said; if the tick didn't solve it and it was installed and adjusted properly you're probably looking at a new clutch. Did you put it in yourself or did you have a shop do it?

If the rear wheels are spinning while the car is in gear and the clutch pedal is pressed all the way in it's probably not an issue related to the shifter...

I AGREE 302% LOL! Very accurate diagnosis!

we installed the clutch ourselves and did not shim, I was hoping the tick could overcome that mistake. Looks like it's coming apart again.
