I don't think the low ratio is working properly on my Rodeo. When selected, it struggles to pull away as though the handbrake is still on, or it is being held back in someway, it struggles to reach 10 MPH.

Just had it serviced, approx. 9500 miles, but the garage think it is ok, although the service receptionist didn't think it felt right. Any ideas on what could be wrong, or am I expecting too much??

Are you using it on Low on the road?

I seem to be haing the trouble on slippery mud surfaces, although at the garage, they did try in through their car park.

Low ratio should have loads of power and set off in first and second without any revs and continue to drive itself as the engine is under less strain than first - I would revisit the garage...

I tried it out again on a wet gravel surface, then up a loose track and it did fell better. On the track I managed to get it up to a bit more speed, but not as fast as the sticker on the door suggests, maybe the surface wasn't loose enough??

On the gravel it did drive itself in first and second, but only slowly.

I posted the same question over at honestjohn.co.uk and got the following reply:

"Is this on tarmac? Can't recall the exact set-up of a "Denver," but most Isuzu's don't have a central diff and engaging low range automatically puts it into four-wheel-drive and this causes severe "wind-up" stresses in the transmission if the wheels can't slip to dissipate them.

Have you tried it on a loose surface. What does the handbook say about engaging low-box? Does it warn against doing it on the road?"

The handbook does say that 4L should only be used on snow, mud or for hard-pulling on loose surfaces.

Hi
low ratio automatically engages 4WD
why would you need it unless off road?
no wonder its slow on the tarmac
cheers
