- Symptoms
- A sharp knock or jolt when shifting from 1st to 2nd, or when changing down from 2nd to 1st while slowing down. The other gears are fine.
- Possible cause described
- An input shaft snap ring (circlip) in the gearbox is out of specification. Hyundai fixes it in service campaign T7E (bulletin 22-01-007H, January 2022): the garage checks the shift shock and replaces the ring, with about 3.5 to 3.8 hours of labour.
- Check for the garage
- Explain that the knock is only between 1st and 2nd and ask them to check whether the car has campaign T7E outstanding, or the input shaft snap ring, before replacing clutches or the gearbox control unit.
