problem is that it is very difficult to shift gears. it will go into gear, but not easily....depends on the rpms. more like shifting w/o using the clutch. getting into 1st or reverse from a dead stop is the most difficult. sometimes have to stop the motor, put it in gear, then start the motor to get going.
this has happened only since putting in 3.4L motor.

the clutch lines have been bled using both a MightyVac and the pumping clutch pedal method. bleeding was done at both the slave cylinder and the other inline bleed valve(cant think of what its called). i removed the slave cylinder and thoroughly cleaned it. its seal does not leak and the bore is smooth. it appears to be in working order. the master cylinder does not leak either.

so, if the system is bled and both master and slave cylinders are working....what else could be going wrong? does the clutch pedal ever really need adjusting? my manual says the pedal should be approx 7.75 inches from the floorboard. but the pedal is ~6.5 inches, and always has been as best i recall. never had a problem before. any ideas what i can do now?
