I believe DOT4 clutch/brake fluid should be gold to clear.

I'm looking to verify this information before speaking to the dealer.

My clutch master cylinder has dark gray fluid with gel particulates floating in it. :barf:

I think this is a problem, but I need to verify.

May I quote you on that?

Check your VIN. Very early GTO's were sent out with the wrong fluid. There was a TSB on it.

I see all the writing about incorrect fluid, but have not nailed a specific TSB#. I don't think it's in here. I've only found the pressure plate bolt torque TSB#.

VIN: L246698

Mine looked exactly the same. Used a paper towel and gently lifted the boogers out.

BOY, don't I know it.

My dealership said they could not recreate the shimmy in the steering wheel between 55-60, and they could not observe the 'fogging' of the driving light reflectors I reported.

That's why I'm looking for assistance before proceeding.

I just think DOT4 clutch fluid should NEVER be black/gray.

Whatever color you would classify brake fluid as. That's all it is.

And as a word of advice, stick with a semi-synthetic blend of DOT 4. Otherwise, full synthetic will eat away the seals and such.

Semi-Syn DOT 4 provides the right heat range without being full syn.

So then dark gray is OUT, right?

That may be the problem we're all having. Full-syn DOT4 is eating our seals and ending up as gel-giz on our clutch master cylinders.

Thanks.

Thanks, mates - I appreciate it.

GM Mike, if you could let me know that would be stellar.

Thanks again.

Just worried about clutch boogers.

Dark grey is probably from the graphite/silicone used in them. So yea, it may have eaten away your seals.

Is this the factory filled fluid for you?

Informational - Discolored, Dirty, Dark, Sludge and/or Grease in the Clutch Fluid Reservoir #04-07-31-002 - (02/16/2004)
Discolored, Dirty, Dark, Sludge and/or Grease in the Clutch Fluid Reservoir
2004 Pontiac GTO

with Transmission, Manual 6 Speed, Tremec, 85 mm, 2.97 First, 0.57 Sixth, Overdrive (RPO M12)

It may be observed on some vehicles that the clutch fluid in the reservoir appears to be discolored, dirty, have sludge or grease contaminates in it after being in service for a period of time.

The level of discoloration will vary with factors such as driving conditions, under hood temperatures etc.

This is a phenomenon that may occur with time due to the interaction between the clutch system rubber parts with hydraulic clutch fluid.

The small amount of sludge or grease that may be noticed is, in fact, grease that has migrated from the master cylinder assembly. The grease is used during assembly of the master cylinder.

Engineering investigations of returned fluid samples show that discoloration and grease in the fluid DO NOT negatively affect the performance of the clutch hydraulic fluid.

Field reports indicate that where clutch fluid and or clutch system components have been replaced to address this condition, the vehicles have returned with the same condition causing a repeat repair and a dissatisfied customer.

Discolored clutch fluid should not be replaced in a normal operating system.

For Clutch System Concerns and Diagnosis, refer to Diagnostic Starting Point - Clutch SI Document ID #1338362.
