You didn't post the machine s/n so we can't look up the configuration of your machine, but if your 6036 is one that does not have the torque convertor attached to the engine flywheel and instead is inside the transmission, and the engine and transmission has a drive shaft connecting the two, if that's the way your machine is set up, then with the engine shut down, if you put a pipe wrench on that drive shaft that connects engine to transmission, you should not be able to turn that drive shaft with the pipe wrench without turning the engine over. If you can turn that shaft and it does not rotate the engine then you have a busted flex coupler.
