Looking for help, my truck is a 94, I6 300, 2wd, 5 speed manual. Last year I replaced the slave cylinder and hose, worked fine, 2 months ago I replaced the master cylinder. worked but now have problem, the system will not hold pressure for more than 24hrs. I have bleed the system to death. Have not lost any fluid, and when the clutch pedal is pushed down, there is a "whining" noise coming from the tranny. Any help would be greatly appreciated.
