I just got my slave cylinder replaced and I assumed the dealer changed my clutch fluid. I was just wondering if the clutch fluid is the same thing as the transmission fluid, and if I should change it at 30k since I just got the recall done about 1500 miles ago... TIA

 

1st of all make sure the dealer didn't just top off the fluid, clutch & traNNy fluid are not the same.

How many miles on your car and when does the manual rec. to change the juices??

 

I'm hitting 30k on my HR.
I was suspecting the clutch and tranny fluid to be different because I read somewhere that clutch and brake fluid are the same? If so, does that mean the brake and clutch fluid shares the same reservoir tank?





The manual here suggests inspecting manual tranny oil at 15k and 30k..

 

How do i check to see if dealers top off the fluid? There's no indicator, at least not that i know of

 

Clutch and brake fluid are the same. They don't share the same reservoir.

They pretty much have to change the clutch fluid if they replaced the slave cylinder because the system has to be bled after the new slave cylinder is installed. You can look at the clutch fluid reservoir which is the small cylindrical reservoir next to the rectangular brake fluid reservoir.

 

In your part of the country y'all do some pretty fancy wrenching. I have just topped off the reservoir before when changing the clutch cylinder before, though I changed all the fluid soon after. I guess y'all could take a look at the color of the fluid or maybe, ask the dealership.

 

Have you changed the slave on an HR?

 

Never, I changed out the clutch cylinder 2 times on my Datsun 240Z. How hard could it be??? Thanks for asking.

 

I ask because it is not the same as the earlier Z's and is much harder to replace (has nothing to do with the issue at hand but since you asked...). It is concentric (located on the trans. input shaft) not mounted on the outside of the transmission. I have done it 3 or 4 times (can't remember) on my HR because it is recommended in the FSM that it is replaced every time the transmission is dropped. This is most likely because it becomes hyperextended and picks up dust that is on the part of the slave cyl. that does not have the seal sliding over it every time he pedal is depressed.

Point being, it requires more bleeding than the traditional clutch fork style on the earlier Z33s because of the location and increased fluid capacity of the cylinder itself. This is why I said they pretty much have to replace the fluid. Note, I did not say that it must be replaced but in my experiences a lot of the fluid is replaced with bleeding the new cylinder.
