Why does the auto transmission in my 2019 MG GS have a delay on take-off when it's cold?

Asked by Marshall

The auto transmission in my 2019 MG GS has a delay on take-off when it's cold. It has harsh gearchanges and the dual-clutch is very rough selecting gears. What could be the problem?

Dual-clutch transmissions continue to haunt some manufacturers with poor reliability and short lifespans. I’m not going to categorically say that your gearbox is showing signs of premature wear, but the symptoms you’ve listed – harsh shifting, engagement delays and general harshness – are classic signs that a dual-clutch is not well.

There are many causes of this; wear in the clutch packs can cause shuddering and harsh shifting, while worn internals and iffy electronics can cause delays in the unit selecting gears. Either way, it’s straight back to the dealer for your car, but at least it’s still within the factory warranty period, so it shouldn’t cost you a cent to have it put right.

This type of transmission works beautifully when it’s in tip-top condition, but – speaking very generally – they have been known to give problems early in life and some manufacturers have moved away from this tech to a more conventional style of automatic transmission.
