Hi,
I’m a diesel mechanic in Australia and I am having trouble with a 140H grader transmission. Serial prefix CCA.
Clutch pressure #8 and #5 in neutral are fairly low and fluctuating, between 0-200psi constantly, once you shift into a gear that uses #5 (3rd gear forward for example) the pressure comes straight into spec, but as soon as it shifts to neutral, it drops down and constantly fluctuates again. Clutch number #8 always fluctuates whether it’s in neutral or a high range gear. Issue was that in high range gears, it’s jerky, as if it’s in gear then out of gear, in gear, out of gear. (Relating to the pressure fluctuating). Has recently had all new solenoids fitted, I have re-tested them and they’re all in spec. All other clutch pressures are in spec and not fluctuating. Any ideas?
Cheers, Jason.
