My 97' Vf-2 is having trouble changing between hi/low gear. Have looked at multiple threads here and elsewhere on Internet. I've sprayed lube through air lines; took cover of spindle and pulled of solenoids and taken them apart and cleaned them;checked the coils with 110v and made sure they all clicked; made sure the bottom fittings in aluminum block were drilled ( already drilled 0.030 by previous owner); sprayed lube down all lines that run from block and to spindle; blew air in piston that switches gears and works both ways with no leaks....one thing that I can't figure out is that air is bypassing through the air mufflers on side of block as soon as air is hooked up to machine. I have not noticed that before. However, when I apply air to inlet of block when block with solenoids was off, no air leaked from mufflers . I've tried everything I could find suggested, could someone please help?????

Thanks in advance,

Kenneth
