Mike.......you do know "milky" hydraulic fluid means WATER in the 5-gals hydro-tranny oil. It doesn't take much water to turn new tranny oil milky. Some "purge" the hydro-tranny case by pouring some "diesel" into the tranny shifter cap. Drain is the 1/2"-pipe plug in the differential. No need to pull the 3"-tranny plug ...nor... the corner pressure port.
There are many reasons yer 3-point don't lift all the way. Best way to find out is to pull the 6"-roundy dipstick plate behind yer right heel and look fer squirts while lifting sumptin. Report back and we'll advise better. .......squirty Dell
