As with any automatic transmission problem, the first thing to do is check the level of transmission fluid in the gearbox itself. These shouldn’t need top-ups, but if a leak occurs, they can lose enough fluid to play havoc with the gear selection and drive-transmission processes. Low fluid can cause a loss of drive in any gear, but could also contribute to a valve-body problem where the lack of fluid prevents the correct gear selection process. Low fluid can also mean the clutch-packs and bands can not exert enough pressure to get the car moving.

It's worth noting, though, that this particular transmission has a finite lifespan and a loss of third and fourth gears could be the first sign that the unit is worn out and requires either replacement or reconditioning. A transmission specialist should be your first port of all.

If you can't find the dipstick for the automatic transmission, there might be a very simple explanation: It doesn't have one. Many Fords from this era were not fitted with dipsticks, so checking the level is done from underneath the car via the a threaded plug. Not so easy to do at home. The transmission is a sealed system, and any drop in level indicates a problem that needs to be fixed. So the level is worth keeping an eye on, even if that's not so easy to do in cars like this one.

Theories for the dipstick deletion include preventing owners from over-filling the transmission (easier than you might think, since the transmission temperature when you check it is critical) as well as not giving owners the opportunity to top-up their transmission with the wrong type or grade of fluid.

At some point though you have to imagine that cost-cutting also came into the decision.

A car with a little extra ground clearance is great for camping as it often allows you to get a little farther away from the masses in their caravans who tend to huddle around the shower block at bush campsites.

The Subaru Outback is a good, solid choice and if you can find an independent workshop to service it, you’ll avoid the cost of dealership prices. And you’re right, the all-wheel-drive would be great for gravel roads. Another vehicle to look at would be a late-model Ford territory diesel which is big and clever inside and has the option of all-wheel-drive. The diesel engine is a plus on the bush where that fuel is more readily available (in really remote areas) and gives you more range for big holidays in the mulga.

Don’t rule out things like the Mitsubishi Pajero, either, which won’t be as around-town friendly, but is a proven quantity and is absolutely tremendous off-road. The same goes for a Toyota Prado or Nissan Pathfinder prior to the current model (which is a bit less hard-core adventure).
