Default 2006.what slave for LS7 CLUTCH

Installed a new LS7 clutch kit...and used an LS7 slave...seems logical, but if I remember correctly I must use an LS2 or LS1.Does that sound correct, cause after bleeding I am haveing trouble getting gears...With the new UCC bushings and the home depot fix with the engine off it goes into all gears really good......HELP
PS: 6.0 iron block or LS2 NOT 5.7

I was told just a LS7 slave to account for the size difference between the stock dual mass and a normal flywheel.

Let me know what you find out. Might need shimming

You need a LS7 slave because of its longer reach and larger diameter throw-out bearing. If you're having trouble finding gears, that means either a) you did not torque the pressure plate bolts to 48-52 ft-lbs on the final pass, b) you did not follow the star of david pattern, or c) you still have air in the clutch lines. My money is on a) because that's what most people have done. This is one of those scenarios where a torque wrench is not optional.

The best slave is still the PowerTorque CS2529, sold by O'Reilly.

My vote is C.

I used a PowerMotive setup and got all of the air out.

I hope the answer is C....the pressure plate was torqued star of david , starting at 15lbs. then 35lbs.then finished with 52lbs.with blue locktite. Might have to get something like the PowerMotive setup, cause no more air is coming out. Every part is new. I sure hope I don't need a spacer. I need a Bud Light.. Back with u'all later.................
ps: calling Lindsay again today..With the holiday I didn't get a return call...

Air... you will not see air coming out, but keep bleeding... mine took me hours... even with a mityvac, speedbleeder and not running it dry (heck it took me forever to even get a pedal, then to get it to feel right)

It's gettting late so I gotta go and order that..can't hurt..thanks guys. $$$$$$$ mo money, mo money YeeeeeeeeeeeeeeeeeeeHa..

You're talking about ATE Super Blue DOT 4. If you think it's expensive, look up Motul RBF 600. That's a solid upgrade and recommended for cars that see track time.

Greg..

The only way I have found to properly bleed any hydraulic clutch is to open the bleeder and have someone push the pedal with the bleeder open. The bleeder must be closed before the pedal bottoms out, however. Once you have a decent pedal, pump the pedal about 15 times and then repeat opening the bleeder and then pushing the pedal, closing the bleeder before the pedal bottoms.

Vacuum bleeders have never worked for me on any clutch system...ever.


Good luck buddy!

Well, I already ordered it...and what u said about the bleeder must be closed before the pedal bottoms out was what my one friend said, but for some reason we didn't do it...I will check into that with them and get back to ya....thanks for the reminder..

I have heard people say this about bleeding clutches, but they are in the minority or are doing it different.

I have had great luck with the typical bleed.

Hell, both ways probably works!

I bled mine manually with my LS7 setup and had no issue. I do have a Mity Vac but I doubt I'll use it for this. I forget which speedbleeder I have, I want to say its the East Coast Corvettes version and I did notch the bellhousing.

I use the Motive Power bleeder. I've had issues like this before and it seems random when the clutch just starts working properly.

If you think the Motul RBF is expensive try the Castrol SRF. That's the only fluid I don't have to flush once a month.
