Just like motor vehicles when transmission gets stuck on a particular place without moving forward or backward it is a sign of a jam in one of the transmission levers. This is usually caused by lack of transmission fluid in the gears.When the fluid or grease depending on what your unit uses gets low the levers begin to grind against one another and therefore bring about such problems as you are facing. Although there is an off chance that the problem could also be from the automatic selector in this case the damage might not be so much probably an electrical fault.
First get an expert to check the auto selector if it is in good shape. If it is then i am afraid the problem is from the transmission levers.
Hope this insight has been helpful?

Hi, remove the battery and battery support tray and clean all debris from around the hydrostatic drive, fan and cooling fins. Your problem is caused by the hydrostatic drive overheating. Hope this helps, regards Phil

check the connecting rod to the tranny. follow the gear handle and you should find a rod connecting the handle to the axle make sure you're in neutral and adjust the rod until the handle starts to move
