There’s probably a very simple solution to this involving a wire that has been disconnected during the transmission replacement, and not reconnected afterwards. You might find it’s a wire to a sensor that has been bumped or disconnected, and without this, the engine doesn’t know it is below operating temperature and, therefore, doesn’t richen the air-fuel mixture to compensate.

This compensation is how modern, electronically controlled vehicles make do without an old fashioned choke lever. But if the wiring isn’t connected and the sensors all working, the car doesn’t have the information it needs to run properly under all circumstances.

If the car drives forward then it’s possibly not the age-old problem of low or dirty transmission fluid that’s causing the problem. Even so, it may not be a catastrophic failure of the transmission and could, in fact, be as simple as a poorly adjusted gear selector cable or linkage. The sensors that operate the rear camera and reversing lights are not necessarily the same ones that actually select each gear, so the fact that they operate does not mean the transmission is physically selecting Reverse gear.

Have the vehicle looked at by a transmission specialist who will possibly have seen this very problem before. Don’t forget, either, that if the car has travelled less than 130,000km and has been serviced correctly, you may still be covered by LDV’s factory warranty which was for five years back when the vehicle was sold new. But get it looked at and the problem logged with LDV before that warranty runs out.

It depends on which particular version of the G10 you have. That’s because, around this time, LDV offered three different engines in vehicles badged as G10s. There were a pair of petrol engines – one turbocharged and one without a turbo – and a turbo-diesel. Both the turbocharged petrol and the turbo-diesel used a timing chain, while the non-turbo petrol (which had a capacity of 2.4 litres) used a rubber timing belt.

As such, the two engines with timing chains should not need maintenance in this area, while the 2.4 petrol’s timing belt will need to be replaced at whatever intervals LDV specified. Workshops dealing with these cars seem to recommend a belt-change interval of five years or 100,000km, whichever comes first.
