these have always been slow/tricky to engage, when stationery particularly when going into and out of low range.

if going from 2 to 4wd do it on the move no problems in or out as long as wheels are straight up to 80kmh.

it will not be a gearbox problem it will be in the slide engagement on the front axle.

regards peter

I had just that problem as well in a rodeo I used for work. Its not the gear box. The problem is quite common in the first of the Rodeos using the electric change to 4wd. It is an electrical fault and to do with the solinoid. I can't remember how we used to get over it. There is junction box under rubber flooring under the drivers seat . We used to re-set it from there. If you see a GM dealer I am sure they wiil explain what has to be done.
Hope this helps.

My 2004 Rodeo Auto does the same , have to have the wheels dead straight and a CONSTANT speed upto 80klm per hr then no problem , also only push the button the once only or the solenoid clicks in/out ,, for low range go into 4H and once engaged STOP and push L4 .

check the solinoid on the front axel if the guard directly under it has any damage or bend have a very close look at the plastic on the solinoid ,any small crack causes loss of vacume and it will not lock in about $400 + from Holden picked up a low km's one from a wrecker for $180 (cant buy the plastic bit)

hi agroe,
i sometimes have a simular problem with my rodeo {18months old} from 4wd low to 4wd high,you must stop,then put into neutral,then engage 4 high,coming out of 4 high is also a problem,it seems to get "wind-up" easy,so just a cpl of ft in reverse does the trick. i have also found that if like me you play around with the dash,i sometimes push the 4 low button by mistake,well i can tell you that makes a problem with windup,as the bloody car wont move to far or fast,and with traffic up ya bum,instant road rage. lol
hope that helps your problem a little more

Thanks to every body who replied. I found two plugs off on the front side of the tranfer box. reconnected one and had to solder up the other one. the original problem was when you pushed 4h the light would flash the tranfer box would engage but the diif solenoid would not engage hence no 4wd. Maid the brain overload thinking it was a computer problem. But it was just asimple disconnected shift solenoid. to simple Thanks again Agroe
