2014 e35i 600 hours stalls and low power and no x change.

I’ve got a bobcat e35i 2014 that i bought with 600 hours that was involved in a roll over. The machine sat for a couple years. I got it running but the x change pins don’t work. It like disables the machine when the button is pressed as if you opened the driver arm rest to step out. My other large issue is that it seems sluggish. If you raise or drop the boom full speed will stall the engine out. Try to take a turn to hard stall out. I changed the 2 hydraulic filters all looked clean the fluid looked clean. The rabbit button does not seem to do much change either. Steve suggested the 2spd solenoid just looking for as much input as possible
