I recently disassembled my 2004R for inspecting after 3 years running. Some info on trans. All CK billet pieces--dual feed---deep sump and pickup--blue printed pump--275 Max. TV pressure. Trans was working flawlessly. The only problem I found was that all 7 direct frictions had a 1/8 to 3/16 in. black ring (burn) on both sides of the friction on the most inner part of the circle. I am using a billet aluminum apply ring instead of the factory ring. I placed a machinest straight edge on the apply ring thinking it may be cupped but it is flat as is the pressure plate and all 6 Kolene steels. The only thing I haven't done is (and I just thought of this) is to measure all the friction from outer edge to inner edge to see if they are the same thickness. These are Blue plate friction. Surely they are true. What am I missing? These friction were holding but IMO they should not be this way. Open to suggestions. Thanks

Did the steels have any bluing?

No

They are Kolene steel but have been in use long enough to have most of the black gone. They are uniform across the surface, color wise.

Raybestos calls those power rings. They don't seem to be very concerned about them. If I remember correctly, they would even suggest throwing them back in.
I would change them out for fresh ones. Three years of running time with thin power rings on 7 clutches in a 200-4R high clutch seems fantastic to me.
Depending on how hard you're running your car, you might want to PM the trans more often.

inspect

Actually that is why I disassebmled it this winter to see how well it was holding up since dual feeding. I did measure the frictions today and they are uniform from outr edge to inner edge. Still don't know why they would only show wear or burn on the inner surface. BTW it is a bottom 10 car with probably 25-30 1/4 mile passes and a few thousand highway miles.. Thanks for the relys.

I'm at a loss to explain that to you. Due to unavoidable pressure plate deflection, maybe the inner diameter surfaces aren't allowed to transfer heat from that friction zone as well.

 

[JDSfastGN]

Ive seen similar before and cant offer an explanation.

hang in there we have some .125 steels and a .375" pressure plate(relieved to clear snap ring of course.can be used with the mettallic .060 frictions.

That .375 plate should help with this a lot. Raybestos blue dont bite like the alto red from what ive seen so there may be a lot more heat there but the steels are not showing any hot spots according to your post. They dont burn out either. Go with the thickest steel you can

 

[Otto J]

every set of blues i remove pretty much no matter how many miles show this.
Every one still shifted like the day they were new.

 

[turbo nasty]

Not a pro but the thicker steels are a better heat sink IMO

Blue Plates

It is normal to have that. What it actually is , is the resin in the clutch. I was around when they came out years ago and we did testing for Raybestos. I can send you a flyer which explains this or you can go to Raybesto's site and read about it. If the steels are hot spotted then you have a problem. If the steel looks good and the clutch has that black on it , it is the resin coming through. call Raybestos. They will talk to you and are good people. I have a TON of experiance with these as like I said we were a testing ground for Frank Slocum and Raybestos back in the day.

No worries....

Good to know--I reassembled using Alto reds (.078). I did save the blues--guess I'll use them in forward some day. It did shift great so I am sure they were holding. Thanks to all who relied.--Lee
