Hi Greg, My name is***** there any other worn bushings in the steering or suspension/axles/hubs? Check for those. Is the swing circle wobbling or the complete machine? What are you getting for fault codes for the transmission issue? Also check the transmission oil and filter for signs of discoloration and burnt smell as well as fine metal/debris in the filter/suction screen, and oil indicating an internal failure occurring. Let me know
