Ok, long story, so bear with me. I have a 1993 F150 5 speed with the 4.9 I6. Last Friday, it ran out of clutch fluid. I re-filled it. I had to pump the clutch to get it to work. Every 10-15 minutes the clutch would need to be pumped again. I bled the line, and it was back to normal. Well, today, I was driving home, and suddenly the clutch got very tight. As I drove on, it was grabbing very late. I pulled into a parking lot to check it out. I pumped it to see if it would change at all, but got nothing. I pushed the clutch, put it into gear, and completely let go of the clutch and got nowhere. It wouldnt grab. Now, the pedal is completely flat to the floor with no tension in it at all. Any ideas?

Sounds like some kind of throwout bearing failure. The throwout bearing is part of the slave cylinder on the M5OD. There's a rubber plug over the inspection port that you can pull to see if you can see anything. I think it's on the drivers side of the bellhousing.

I spoke with my grandfather, and he also said it sounds like the throwout bearing. If it is, would I have to take the whole transmission out, or is it possible to replace the slave cylinder while its in the truck? Thank You

You're going to have to take the transmission out since it's a concentric slave cylinder (it's on the transmissions input shaft).

I concur. If it is inside the bellhousing, you will need to drop the tranny. While you are at it, look at and replace if needed the clutch kit. Otherwise if you need to later, you have to drop the tranny again. Finally, if the slave is bad, think about the master as well. Note: Some parts stores sell the throw-out bearing in the clutch kit, it can also come with the slave cylinder, or you can buy it by itself.

SIGNATURE. If you're not going to follow my suggestions, I can't help you. READ those captions - "stock" and "OE" are meaningless. If you changed something, we need to know why, and to what.
