Software update using an IID tool sorted my gearbox issues and is known to help the 2-1 thump issue. |

Thanks mine is on 78k atm, shall see how I get on with the oil. Just been out for a test run and dose do it in manual if you catch it wrong the car can rev up like it’s in neutral before it selects 1st.

Mostly the gearboxes don’t want to select first,generally they will pull off in 2nd only picking 1st if you bang your foot on the gas. There is nothing that can't be fixed with a hammer😜😜

My 2007 4.2SC has a distinct slight shunt in the transmission, particularly when changing from deceleration to acceleration at very slow speeds. It's not a big clonk, just a slight shunt you can feel. Like above, it also rolls slightly on taking up park. I suspect it's transfer box or diff related due to mileage and heavy city use prior to my ownership.

Changed the oil and the 2-1 knock has gone. The 3rd gear transmission fault was low voltage on the battery so changed that and all is good again. 2007 sc |

Oil change sorted out a poor 2 to 1 shunt on mine too. |
