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.

It’s a bit hard to imagine how removing and replacing a transmission could make an engine misfire or backfire. Unless, that is, you’ve managed to bump part of the engine’s electronic controllers, wiring, sensors or even something as simple as pinched or displaced a vacuum line somewhere in the engine bay. Incorrect ignition timing can make an engine do this, but, again, that’s nothing to do with the transmission.

It could even be a complete coincidence. But did the vehicle sit for any length of time while the transmission was being fixed? You might find the battery has discharged over time. Modern, electronically-controlled engines do not like low battery voltage and can run poorly as a result.
