Hi all, having a problem with my 1998 Komatsu D65-12..The machine has no torque inlet/outlet pressure,I have replaced the valve on the side of the transmission but still nothing and I am getting a transmission relief pressure of 30 bar I even have this pressure at the bottom test point on the valve.We have taken the Transmission out and no damage to be seen anywhere.No filings in filters.Has anybody any ideas what could be wrong?? I'm out of options at this point any comments much appreciated

What pressure range of gauge are you using. What are the symptoms that made you check torque converter pressures?
