A switch from top to tow
I HAVE heard of manual and automatic gearboxes failing when towing caravans in top gear. Is this a common fault with modern day gearboxes, or is it just coincidence. I have just purchased a Hyundai Terracan diesel automatic. Should I be towing in top or third gear? The dealer says top gear is quite OK but I still wonder. John Honisett, email
Hyundai tells us it is OKto tow in top gear in your car but I would advise you to use the best gear for the situation you find yourself in. Use top gear on the flat, but instead of waiting for the transmission to change down when you hit a hilly section, anticipate it and pull it back manually to negotiate the inclines. That way the engine will not be labouring and the transmission will be under less load. Hyundai also recommends a different service schedule for cars being used for towing— see your service book. WHIRRINGWORRY MY 2011 Holden Barina Spark had the gearbox replaced at 10,000km and now, at 30,000km, the whirring noise when turning left seems to have returned. Should I insist on having the gearbox replaced again, as there appears to be a definite fault with them? I am mechanically minded and found the fault but how many other cars have it? It’s hard to pick. Have other owners had similar troubles?
Sean, email You should insist on having the problem resolved. But I would not insist on replacing the transmission straight up because the problem might not be the gearbox.
Big strain: Towing a caravan can take its toll on a transmission, so anticipate when to shift gear before the engine begins to labour
