what is going on with my clutch?

Well, yeah, but it's also not uncommon for drivers to ask us for clutch fluid when what they have is a linkage clutch which needs adjustment. So that, plus I just don't know if anything other than the Volvos and the T680 are using hydraulic clutches.

 

It is hydraulic. When I worked in our shop, one of our drivers (in a prostar) called and said he was 2 miles out and had "no clutch". He came in and I checked the fluid and it was empty. Put some in it and started to bleed it and it had a tiny tiny little pin hole where the line rubbed against the firewall/inner fender. Replaced the line, filled, and bled. Good as new.

If it does it again and you happen to be at a red light or something and need to get it off the road, turn the truck off, put it in a lower gear like 1st or 2nd and crank the truck with it in gear. If you have to stop again you have to knock it into neutral before you stop then turn the truck off and repeat when you are ready to go again. It isn't the safest thing to do but it will get you out of the middle of the road.

 

Hi BulletProof, if it was out of fluid, why would it suddenly work again, plus I think you'd see a puddle. I think it's a spring issue, either on the disc or the pressure plate, or like someone else suggested, a pilot bearing may be beginning to stick, but the truck isn't that old, and a spring could go on a truck 2 years old.

 

Didn't know you could do this with anything but older manual cars... Good to know.

With those particular symptoms, I don't think it's a broken spring, because when the truck cooled off the clutch came back; and, since the clutch uses brake fluid, and brake fluid can boil if the line gets too close to something hot, it stands to reason that's a likely source of the problem.

 

Happened to me about a month ago....2013 Prostar...slave cylinder....there may be a recall since they sort of knew what was wrong before the tow truck finished unhooking.

 

Also happened to me yesterday. Went out and came back numerous times and seemed worse in stop and go traffic when one would think it would heat up.

Let it it cool just a bit, and it would act normal.

 

The ProStars indeed do have a hydraulic clutch

 

Please help I just had my clutch replaced and now when I mash clutch in with it in gear truck still pulls and trying to get it in and out of gear is very hard

 

Take it back to whoever replaced the clutch
