Transmission problem: friction point changing
So I've been having this on-going problem. I got my clutch replaced a year ago. 10,000 miles or less have been put on since then. Trucks an '01 2WD. Anyway, every once in awhile the friction point on the clutch changes. The pedal becomes saggy and has loads of play and the FP is basically an inch from the floor. Normally the pedal is firm and the FP is nice and happy. Seeming like a pressure problem, I'll pump and pump and pump on the clutch to build up pressure. This fixes it for a minute or two. For a long time this problem just fixed itself, I couldn't tell if it was temperature or how I was driving or what, but lately it's just been staying real junky. I went on a round trip 4 hour drive yesterday and by the time I got to the destination 2 hours in it was back to normal. This morning while driving around town I felt it just become looser and looser.
Yes, I've checked the fluid. It's been at the correct spot (I THINK) ever since I got the car, and I've never had to put more in. Should I change it? is that the problem?
Also, I've recently moved to a new area.. the street I live on has a stop sign every 30 feet. Of course my P.I.T.A. granny first gear HATES being re-engaged once the car is moving so could that lurch be the cause of it? AND FINALLY, because of that annoyance I've been roll starting in second gear quite often lately, and shifting into third a bit sooner then normal. Is that causing this annoying problem?
Sorry about long post.
