I see where the clutch fluid fill area is just in front of the Drivers side Dash. It says something about using Dot 3 fluid??? I checked it and it was full. I have never heard of anyone servicing it or fluishing it out?? Would this be recommended?? I have that little bit of noise when the clutch is in Neutral. Goes away when clutch is pushed in. . Switching to AMSOIL ATF4 in the trans, just didn't know if flushing this system would also be advised? Thanks!! Oo.
