Yet another shifting thread lolz

K, perhaps you gents and ladies can shed some light on things. Just trying to get some additional opinions before I go replacing parts lol, or get an idea on what I need to replace.

Issue:
The car shifts fine when its off, when the car is on sometimes it shifts perfect however most of the time it either grinds or wont go in gear and I either have to wait a sec and try again or blip the throttle a little.

** I have had issues recently where it wouldnt go into gear at all to save its life, however I parked it and the prob went away after a few minutes and isnt present again for while this has only occured 2-3 times. **

Things I have done thus far:

Rebuilt my Master and slave cylinders. Bled the entire system, No leaks and the pedal has a good feel to it. Also you can see the slave move when the clutch is pressed moves around an inch or so.

Things I have not done...

When I rebuilt the engine 2 years ago I never replaced/rebuilt my transmission as far as I know its original.

I also did not install a new clutch at this time because the one on there looked good.

Things I believe could be the problem...

I need to adjust my clutch pedal??? (i doubt it is this as I feel the pressure engage about an 1.5 inches or more from the floor and the slave is moving. however I am welcome to try it again lol already adjusted it out once.)

My trans is shot... while I am sure I could use a rebuild/new one I doubt this is the prob...

My clutch is going out... I am inclined to beleive this since it feels like it grabs alot when I am going slower (such as pulling into/out of a parking spot where the speed is really low).

Thoughts..... or does everyone think I am on the money.

Check your shifter bushings imo. Easy and cheap install.

Maybe your clutch is beginning to slip, but check all the little stuff first like ^ said it may be your bushings are messed up and need to be replaced (which is cheaper and easier then dropping the trans)

i have a grind like that too, and its only when the motors really spun up that it does the grind consistantly and my brother who used to race a first gen said it was the clutch being worn out, but not glazed.

I will look into the shifter bushings. as for the grind mine happens whenever lol not just a certain rpm range.

Okay, just ordered this from twosrus. Will let you all know if it corrects the problem.

I will get pics of the problem part up soon, however here was my fix...

While I replaced the shifter cable bushings they were not the problem (altho they did help and needed to be replaced I have the old ones and will post pics.)

The problem was the part that connects to the clutch master cyl push rod and then pins onto the clutch pedal. This part was bent and therefore not engaging the clutch as it should.

Like I said I will post pics soon.

I got a new/used one of these from my local yard for $2.50 off a ae86.
