Bad Tranny? Clutch? Master Cylinder?
Hey guys, like the title says I am having a problem in that field. The last few days it has been hard to shift into 3rd and 5th, and today I was parking and went to put it in reverse and it wouldnt go in it was just grinding as if I were still rolling at a higher speed. Is there anyway to know for sure what my problem is? My clutch is ran by the master cylinder right? My truck info is in my sig!
TIA
Julian

i would make sure your master cylinder had fluid in it, if it was low or spongy maybe you got air in it? throw out bearing would prob be making a little noise if the bearing was worn out. can you feel the clutch slipping any starting off? is the tranny making any noise? when you push depress the clutch does it change any? when i just put in my stage 1 centerforce it was grinding going into rewind but that was due to me forgetting to adjust the clutch pedal... might want to check there. Sounds like a synchronizer in the tranny or one of them shift fork thingys i sure someone better than me could diagnose it with the little info that you've given-- hope this gives you a place to start

All the way to the floor sounds like a failing hydraulic component to me.
Try adjusting your clutch pedal to within spec, and make sure you check your clutch pedal bracket for cracks as they are a known failure point.
Make sure the clutch master is operating correctly by measuring the piston movement (or at least eyeballing it) to see if it moves enough. If not, you can figure you have a problem. generally 1st, 2nd, and 4th are the easiest gears to get into. However, 3rd and 5th are well known for having syncro problems.
One last thing to check is the shifter seat bushing. Make sure that is intact, and replace as necessary.

If it doesn't rev up on hills/acceleration, the clutch itself is fine. Sounds like a hydraulic problem. You say the MC has fluid in it, so I'm guessing the MC is bad. If it was the line or SC, you would be losing fluid. Try pumping the clutch pedal then . If that does it, one of your cylinders are blowing by.

for a 1990, i wouldn't be suprised if your slave cylender went out. check for quick fluid loss when pumping the clutch pedal, as well as fluid ALL OVER THE BELL HOUSING!!! (personal exp)

If you lay under the truck under the passenger door you will look up and see a rubber boot thing on the side of the transmission. If you pull the boot back you will see a steel arm sticking out with a rod pushing against it. Have someone press the clutch pedal (not running with parking brake on) and see if the rod pushed the arm. If not then you have a master cylinder/slave cylinder problem. Or common problem of cracked clutch pedal bracket. If it does push the arm then you have a clutch finger/plate or seized pilot bearing problem.

Well, I got it to the shop to get fixed. Picked it up yesterday, They checked everything to be sure that I didnt have any other "serious" problems. I asked the mechanic how it turned out, he said there was absolutely nothing left of that clutch that it was basically a metal frisby. I'm willing to bet that it was the original clutch. Just last year we found out that the fuel filter was the original so I was guessing that was too. turns out it had to have been! Happy to have my yota back! Drove a 2008 dodge 1500 and love the truck but love the yota more!

Last weekend I swapped my W56-C for an older G54. Put a new clutch and throwout bearing in too. Drove it for 4 days, fine. Now when releasing the clutch in first gear, it grinds and wont engage. Is this a clutch issue or did I get a bad tranny. I bled the clutch last night. If anyone has any info it would be awesome.
