Manual vs Automatic Transmission Vehicle Off Road

manual vs automatic

Which transmission is better off road, a manual or an automatic? This is a very hot topic within the 4WD community. The old school manual drivers will swear by their manual vehicles while the automatic drivers will say that they will never change to a manual. The fact is that both have their advantages and disadvantages in various situations. But due to advancements in the automatic transmission technology, it looks like the autos are winning the argument.

Let’s take a look at some of the advantages and disadvantages of both transmissions.

In general, manuals give better fuel economy. You select the gear you want to drive in during certain situations, instead of having the vehicle change the gear according to what it thinks it should be in. However, the newer transmissions with 8, 9 or 10 gears actually give better fuel economy than the manuals.

The gearbox of a manual is much lighter than that of an auto. In off road situations, less weight is better.

An auto transmission tends to heat up more than a manual when driven in tough situations. An after-market auto transmission oil cooler will help with that issue.

In terms of driving control, you can drive very slow in an auto compared to a manual when tackling the technical parts. A manual vehicle will already be moving at around 3 to 4Km/hr. upon release of the clutch, while an auto can be driven at 1 to 2km/hr., giving you better control.

What about wear and tear? Well, a manual transmission will be subjected to more wear especially on the clutch and flywheel when you have to get unstuck in the mud or sand.

This is an important plus for the manual vehicles. You can push-start a manual when your battery is dead. You can’t do that with an auto. This will be a problem when you cannot find a jumper cable anywhere. To get out, the auto will have to be towed.

In the event of transmission damage, with a manual, you can enter a gear that is good and still drive your vehicle home. In an auto, the transmission requires fluid to work. If the transmission fluid has leaked out there’s no way you can drive the vehicle.

And if you have to replace your transmission, the automatic gearbox will cost much more.

A manual is quicker off the line in a standing start. The auto transmission depends on fluids which take a moment to build up enough pressure to send power to the wheels.

The auto gives you better performance on the sandy tracks, at the beach, as well as on muddy tracks. It also gives more control when driving over rocks, tree trunks and other obstacles.

In the event of a water crossing, you put your manual into 2nd low range and start to drive through the water until you reach the other side. In the event that you need to change gear mid-way, water can enter your clutch, causing slippage and damage in the long run. An auto has a sealed gearbox which allows you to change gear while still in the water, without the fear of water entering the transmission.

Hill driving gives mixed results. In a manual vehicle, when climbing a very steep hill, you have to select your gear at the bottom of the hill and stay in it until you reach the top to be able to maintain a steady momentum. In the event of overcoming an obstacle or facing loose surface material, changing gears will cause you to lose momentum. There is a risk of the vehicle rolling backwards to the bottom of the hill and facing damage. Autos gives you better control and safety if your vehicle ever stalls mid-way up. In a manual, you need to balance the clutch and brake well to prevent the vehicle rolling back, or prevent wheel spin and lose traction. The auto gives great control in this situation and will get you moving upwards safely.

Downhill Driving in a manual on 1st gear low has better engine braking for most manual diesel versions, as compared to that of an auto. The auto will come down a steep hill much faster than a manual. However, the modern auto with hill-assist and traction control, is better than a manual for steep hill descents.

Conclusion

 In my personal opinion, auto is better, safer and easier to drive in most situations off road. But it all depends on your personal preferences and how good a driver you are.
