Transmission problem
1994 Other Isuzu Models 6 cyl Two Wheel Drive Manual 68000 miles

iv replaced the master and slave unit on the clutch iv bled it 10 times the pedal works fine for a few days then starts slowlys going down iv check for leaks theres none what could cause this

I assume when you rebleed it is O.K. If so try this put a clear plastic tube on bleeder place into a contanier of fluid. Open bleeder have someone pump pedal, until no more bubbles. Keep eye on master fluid level.
