Hello everyone!

I was hoping that someone might be able to help me. I was talking about this in one of the other forums and I was refered over to you all. I have a '76 f-100. About 6 months ago my trany went out due to an emergency installed auto zone shifter. I put it in a shop here and they installed what I was told to be a rebuilt tranny because the snyncros was out in mine. It done well for a few months( almost exactly the length of the warranty-90 days), then one day out of no where about 2 months ago, I was making a turn and it wouldn't go into gear. I was about to get hit so I had to force it in gear and the shifter broke off at the floor! Well, after sitting all this time because I was gone at work, I just got it back running again this week end, and welded the shifter back on. I quickly found out that something must be wrong inside the tranny, because it won't go into any gear at all. It is almost like I am not pushing the clutch at all and trying to shift with out it. Also, I noticed that when I have the clutch comletely depresed to the floor the engine sometimes sounds like it lugging down like it does when you let off the clutch some but I am not. One time today when I turned the key with the clutch down, as soon as I turned it off the truck jumped a little like the clutch was still engaged with it all the way to the floor!! I just want to know how I can tell for sure that it needs a new clutch throw out bearing and pressure plate before I buy it. I am very limited as far as money goes and can't afford to pay anyone, so I have to do what ever it is myself. I just don't know how to determine what it is I have hve to do for sure. Any help would appreciated, because I am a painter and I really need my truck back.

Thanks,
michael

 

Have somebody push down on the clutch pedal while someone watches the clutch lever to see how far it moves. Limited movement may mean that the pedal is not getting the job done and the throwout may still be good.

 

Good advice from Shorebird. However could you give some more information? I am not familiar with your truck so is it a mechanical clutch linkage or hydraulic? Also can you get it to go into any gear with engine off? Do as recommended by Shorebird and report back.

 

Yes sir. In fact I had it towed over here to my new my new house, and after getting started again after sitting for a while, I had to put it in gear with the engine off just to get it off the street and up the driveway. It is a mechanical clutch to by the way.

 

I done that yesterday. I had a neighbor friend push down the clutch while I watched. There was movement all the way to the tranny. I just don't know how much movement there should be. I also know that saturday, I went underneath, and the what I think is the adjustment rod, was adjusted all the way out, right on the edge. It is exactly the way it was when it left the tranny shop here and it was doing fine. Then shortly after the warranty expired so did the tranny!!

 

It sounds like your transmission is OK but the clutch will not disengage. So some more questions for you. How much free play have you got at the clutch pedal? In other words if you pull the clutch pedal fully up how far does it go down before it goes firm? Next have a look at the firewall where the clutch pedal assembly is fixed to. Any signs of movement there when clutch pedal is pushed down? Next when you were underneath with the pedal being pressed did you notice any movement of the engine? Finally (I think) could you go back under and pull the throwout lever hard toward the rear of the truck then measure how far towards the front you can push it by hand.
Sorry for all the questions but from your first post it seems like this happened suddenly, as if something broke. Now it could well be something internal but as well to cover as many other (and cheaper) options as possible.

 

That was all the first things I looked at. I guess you didn't see my other posts. I have since fixed the problem. What it was, was for some uknown reason, both bolts that held my drivers side motor mount to the block were gone. MIA. LOL. It was literaly all jacked up. Once I set it back down into place and bolted it down, it was fine. It was just in a bind and I had know idea to look at the motor mounts. Thanks for the response and advice.
