Machine serial # ?
What happened to the main hydraulic pump ?
Does the engine sound like it is loading up roughly the same amount when stalling the bucket over relief or stalling 1 track over relief ?

Sounds like maybe the load piston that actuates the swash has a broken seal ring and is getting stuck
