I have been told not to use fifth gear when towing my 1500 kg 17-foot Jayco caravan with my 2004 Nissan Navara 3.0-litre turbo-diesel five-speed. I use fifth at the moment and don?t change down until the revs hit 2000. I have been told that by doing that I will destroy fifth gear. What?s you advice?
First thing you should do is check your owner’s manual for any advice Nissan offers for when towing. Patrols had problems with fifth gear, so you need to be a little easy on the gear. Use fifth, but don’t let the engine lug down too far, change down before the engine and driveline become stressed. I would think 2000 revs is a pretty good downchange speed.
