Transmission problems l3240 hst

[tmfbarton]

I have a L3240D and have lost almost all transmission power in forward and reverse. The engine runs fine and throttles up. I have replaced the electronis ecu module with no sucess and I am now starting to look at the relief valves and regulators. any ideas?
