So this is a question that could really be discussed for any car, but since it is a Toyota pickup I thought I'd see if other owners have experienced this.

It's a 1987 4 speed. Today while driving my clutch pedal suddenly lost all resistance and just fell all the way to the floor. It was a strange sensation. Kind of similar to when you think that there is one more step at the bottom of a flight of stairs when their really isn't. haha

When the truck is turned off I can still freely shift between all gears without any clutch use. When I start the truck (it still starts fine when the stick is centered in neutral, I have not tried to start it while it's in gear - just doesn't seem like a good idea) it does not want to go into any gear and I have not tried to force it. But when I move it towards reverse it suddenly starts to grind a bit. If I do the same towards any other gear the truck will creep along very very very slowly when I'm on a level surface even though it's not going even close to being fully in gear.

I'm going to be doing more research and the truck is at a garage now, but I'm hoping to get honest opinions from others who are impartial (who aren't expecting big bucks from me for repairs like a garage is) and who maybe have experienced this similar problem.

I guess it basically kind of feels like the clutch is stuck closed. Could this perhaps be as simple as a broken linkage or cord or something in that vein? I'm only semi auto savvy. Also, I've never tried before until now, is it normal for a Toyota pickup to start up when the stick shift is centered in neutral without using the clutch?

Thanks.

After doing some more research I'm starting to think that it's the clutch master cylinder. Although I did not notice any leakage of any sort.

Looks like I can get one rather inexpensively here:

I'll find out in a few days from the garage what the diagnosis is along with a quote, but I bet this is a good guess.

Anyone ever replace one of these themselves? Difficult or not so much? I think I may try to tackle this myself.

Also, what I am trying to say in that first post is that the clutch is not disengaging.

It's as if you went out and started your car and simply had no clutch pedal with which to disengage the clutch and shift to another gear.

I had the same problem with my truck. turns out my hydrolic hose was extremely rusted and it broke. I was not able to shift just like you were not able to. for a new hydrolic hose ur looking at about 100 to 150 bucks for the fix. good luck

Check your slave cylinder underneath the passenger side mounted on the side of the trans. It applies pressure to the clutch fork to disengage the clutch. When I bought my 1990 Pickup 22R, that's one of the first things I had to do. What you're describing is exactly what happened to me. They only cost about $15-20 at your local parts store and only take about 20 minutes to replace, but then you need another person to pump the clutch for you while you bleed the slave cylinder to get all the air out of the lines, etc. Good luck.
