I'm working on my dad's tractor, shifts good when it's running
above 1500rpms transmission pressures are all OK and tractor
shifts good shifts normal. When at idle to 1500rpm. Sometimes it
will shift but most of the time it will not. At idle c1,c2,input
brake,b2& c3 are 0 psi. Hi low input clutch&b1 has full system
pressure in every gear. B3 has system pressure in 1&2 reverse
and 20psi in reverse 3&4. B4 has 17psi in all forward gears.
If I put shifter in gear at idle and then increase engine speed
trans will not shift until I move shifter from forward or reverse
position to the left and back to the right. If I idle it down I
can make two shifts and that is it until lever is moved to the
left and throttled up again. Pump pressure is 170 at idle &200at
full throttle pilot pressure is the same.
