i have a hangcha reallift rw26 i am working on which is very similar to a utilev ut25 except different engine mine has the gm 3.0 vortec. when you put it into gear you can here it engaging and sounds like pressurized fluid is going thru in both F and R gear. Ramp up rpm not even slight movement so i assumed clutches.Changed clutches and had a better pump i knew was good i changed it out with and still doing same. I have changed the inching assembly and put all new fluid and filter. Is my transmission itself a goner or is there something i am missing.Only thing i have not checked is in housing filter.
