Just bought this old beauty and ran into a transmission issue. It has a Clark 2420 with a 273 converter....and seems to slip in low or high (both forward and reverse.....some movement, though not significant...crawls at about 1mph). Shifting into High "range" for 3rd and 4th.......no movement in either forward or reverse. The pressure is showing 270 from the converter. I changed the fluid, filter, checked the sump filter (was spotless) and the magnetic plug was clear. My thoughts are to:
Check the pressures at the clutches (1/8NPT plug) for 260.......if good, then look at the high/low valve and then the high/low "range" valve.
Any thoughts would be really helpful. I'm a closet mechanic, though far from proficient when it comes to transmissions.
Thank you
