ok when i am driving on the interstate the clutch pedal goes to the floor. and doesnt want to work. i mean it stays engaged for me to drive in 5th gear but i have to manually pull it back up and then pump it to prime it back up to work then i can down shift and go. when i drive around town it doesnt do this just only on the interstate cruising about 70-90 mph.

 

your spead really wont affect anything to do with your clutch, what it seems is you have a faulty clutch master cyl and a leak somewhere, i would definitely look into that before it gets serious.

 

well the clutch resevior stays full so there isnt a liquid leak or were you describing some kind of pressure leak. i apoligize for my ignorance, but thanks for the info so far.

 

i just recently had the same problem
i replaced the slave cylinder and all of my woes went away so far
i only did it last noght but i have done a bit of interstate driving since i finished
i also replaced my clutch MS while i was at it

 

aight well im gonna bring it to a shop and see if they will check out the clutch master cylinder and slave cylinder.
