Hello, my name is Bobby. Thank you for the question. Can you tell me if you noticed if it shifts even slightly better if you pump up the pedal a little first.

i have dot 4 brake fluid in the clutch res. and dextron 3 in the manuel trans gear box
Expert:  FIXITMAN replied 1 year ago.

Thank you. What you need to do is see that the slave cylinder travel is when the system is working fine as opposed to when it is not. If it is the same amount of travel then that is not the issue. It will end up being due to the shift fork binding or the shifter bushings themselves being worn. I have seen the wrong or old fluid cause this also. Does your under hood sticker specify Dexron 3?

question if this could be caused by shift fork binding or the bushings being worn , how come it only happens after driving several miles or warm trans. temp?

Please continue, the post question and is there a a chance the release fork from clutch to throw out bearing be bent. It now seems to ( clutch petal go down to floor) when pushed I have to hold foot on brake to keep car from moving
Expert:  FIXITMAN replied 1 year ago.

If the fork was bent it would happen all of the time. I am thinking that it is binding when it gets hot. If the pedal is now going to the floor then you need to see if the slave cylinder push rid is moving. If not it is a hydraulic issue unless the fork is not moveable.
