Drill Mod?

[OneSlowLS1Vert]

I was searching around and some people were talking about a drill mod on 98-02, I derived it relates to the slave cylinder. I did a search and didn't really find much information on it.

What is the problem? What is the drill mod exactly?

Is this something I should be considering doing for my 98?

If you have a 02 WS6 you dont need to do the drill mod because GM fixed the prob right?

restrictor still there, only update was the slave

The 1/8" bit won't go past the fitting. Do I need to drill out some of the fitting too? That won't cause any probs will it? One step smaller will go past the fitting but it didn't take much to drill it past the restriction in the line and I'm still getting funky clutch action after hard, high shifts.

fitting ? I drilled mine out to 9/64 because my 1/8 " bit was broke

[Tobynine9]

Yeah, the exterior-most orifice is smaller than 1/8". From what I understand, I could certainly be wrong, the restriction is past this point, within the line. Drilling the restriction out with a 1/8" drill bit requires you also drill the orifice of the fitting out to 1/8", at least it would on my car.

i have a 98 trans am with a spec stage 3, and a mcleod slave cylinder. i didnt do the drill mod, and after did the clutch/slave swap i dont have those problems like my old spec and stock slave. i belive the new slave has a slightly bigger bore but the master is still stock. i have no problems shifting or launching
