The reverse gears are very clean, still under warranty, and free from any defects. I regularly grease them, and currently, they have original thermal grease with no leakage or issues, Alhamdulillah. Right reverse gear number: 49501G8250 Left reverse gear part number: 49500G8100 Reason for sale: Wrong diagnosis—I replaced them and found they were actually fine. The ones I installed are new. Guaranteed to be free of any defects. Serious inquiries only via WhatsApp.
