Well, now that it is cold, my clutch is startin to stick in the morning, maybe the first 2-3 minutes of operation.

I guess if I did what I should, crank the truck up and let it sit for a 5 minutes, I would never notice a problem. But I don't.

It hapened first last week, it was about 40 degrees outside, had not made it to freezin the night before. I threw the truck in reverse, came off the clutch, backed the truck up, pushed the clutch in, and hte truck kept goin under power. hit the brakes and it felt like I was tryin to stop an automatic car that was in gear. I came off the brake, and the truck started going in reverse again, under power.

I had to turn the truck off to force it out of gear and into first, it stuck in 1st for a few seconds, then all was fine.

It did the same again this mornin, aboubt 40 degrees outside, stuck in 1st and second gears, it actually felt like I had the seat too far back and wasnt gettin the clutch in all the way.

In hte past 80k miles, the clutch has slipped maybe 4 times I can recall, but has never stuck before last week.

Clutch fluid seems fine, I have never had any work done on the tranny or clutch

 

it sounds like the accual clutch "Mechanical part" is fine i would bet the the hydro master or slave need to be replaced, probobly the slave which is a pain to change it requires trans removal but since your in there mine as well change the clutch to since it has 80k on it but if your cheap like me just the $70 slave should solve this and also make sure you buy a quality slave oem or luk brand i had problems with others and have read others having problems as well

 

you may try bleeding the slave cylinder real good.

 

I have the same engine and transmission (04 heritage, which appears to be a regular 03 F150 with different stickers on it), and the exact same problem. I crawled under and looked today. I can't see a bleeder valve anywhere. I also don't see any way to replace just the master cylinder. The hoses from the resevoir and to the slave cylinder look like they're just molded plastic, part of a whole assembly.

Any advice on how to bleed this system would be greatly appreciated. 92K miles and this is the first problem. I'll buy a factory manual if any are available. Ask the dealer and they about come unglued trying to talk you out of it.

In the mean time, if I have to pull the transmission, I will resurface the flywheel and replace the clutch and disc and slave cylinder at the same time, since it's such a pain to remove and install a transmission. This will force me to say bad words in large quantities loud enough for the neighbors to hear, thereby causing me great embarassment... well, with luck that won't happen.

Thanks.

 

the bleeder is a few inches above where the clutch line enters the belhousing

and you can replace just the master cylinder if you go buy one and look at it you will understande how to remove the line there is a small roll pin that needs to be knocked out and then the line simply pulls out
