Manual vs Automatic Transmissions

Settle the Difference between Manual and Automatic Transmissions What are the differences between manual and automatic transmissions? Operation Perhaps you've encountered various technical definitions between manual and automatic transmissions that you can hardly understand their generic functions. Simply put, manual transmissions mean you have full control with your gears while with automatic you can limit your choices between two pedals. These alone already provide their basic distinction. Manual transmissions work well if you like to be the ultimate master of your vehicle. It gives you more freedom when it comes to maneuvering your car on steep hills or curves. It will also allow you to combat tough weather conditions more comfortably than when your auto has automatic transmission. It doesn't mean, however, that automatic transmission is futile. Because it's very convenient to operate, you can breeze through traffic more easily compared to using automatic transmission. Second, it won't take you much of a long time to determine how to navigate with automatic transmissions. It's even like driving your own go-cart. Costs Though automatic transmissions mean ease of use, they do eat up too much fuel; thus, if you're trying to save on fuel, make sure that you're not settling for automatic transmission. You can save at least 10 percent in fuel economy if you go for manual transmission. Besides, automatic transmissions are known to be ultimately expensive. They have a starting market price of $700. When it comes to repair and maintenance costs, manual transmissions appear to be more superior. They don't need too much refining, so you can definitely save huge bucks in your maintenance and repair budget. In fact, there are a number of car manufacturers who believe that manual transmissions don't need too much in the way of fluid changes. On the other hand, if ever manual transmissions go haywire, they don't cost a lot to get fixed. The clutch, which is one of the most expensive components of a car and the most labor intensive when it gets damaged, is more maintained easily in manual than in automatic transmission. To make matters worse, if your automatic transmission breaks down somewhere, you have to bring jumper cables with you. Otherwise, you won't be able to restart your engine. If this doesn't work, your last recourse will be the towing company. The Birth of Manumatic Transmissions During the onset of the twenty-first century, there's a new transmission method that was introduced by automobile manufacturers. It's referred to as the manumatic transmission. It is an automatic transmission that possesses certain manual-transmission features. A good example are the luxury cars of Chrysler. It's definitely automatic, only that you have more control in shifting your gears. Shopping for the Right Transmission When you have chosen your own car, make sure that before you actually buy it, you've already performed a test drive. This is to ensure that it suits your taste and your current need. You may also have to check on the EPA rating of your vehicle for both manual and automatic transmission. Keep in mind that this is not completely accurate, but at least it can provide you of a good idea on how much fuel your car can use. Choosing the Right Transmission In the end, when it comes to choosing which is which, you shouldn't limit your decision based on pros and cons of each. Rather, think of your car and what you truly need. For example, if you're going to get an Audi for maximum performance, you may want to consider getting a manual transmission so you can have control over its power. If you like to minimize your movements while you're driving, especially in the midst of traffic, automatic transmission is your best choice.

Prepare Your 4x4 Vehicle For Africa

From years living and working on the African continent, providing services to thousands of tourists and meeting dozens of independent travellers it was due time to explore the top ten tips for those wanting to embark on an African adventure in their own 4x4 vehicle.
You have spent years reading every book written about Overlanding from Cairo to Cape; you have bought all the lonely planet guide books and spent days on the internet researching your epic journey. The decision is made to go ahead and do it. But before you run out and spend thousands kitting out your beloved 4x4 or worse buy the ideal vehicle you should read this.
1. Concerned over not knowing what is out there many people take their car to the Expedition Preparation shop. These people would sell you anything under the sun "as long as it is checker plate it must be good". "You must have these tyres for Africa" but they don't tell you that particular tyre size and make is not available anywhere in Africa. So after your first blow-out you are stranded. The USD$2000 latest technology aluminium roof rack looks great but chances are it will crack on African roads and the two places that have a specialist who can weld aluminium are in Nairobi and Cape Town. If all the "must have in Africa" equipment was that good and essential then it would sell in Africa and not in the western world.
2. There are a million brackets available to hang jerry cans, gas bottles, high jacks, sand mats, shovels etc to the side of the vehicle. If it doesn't fall off chances are you will wake up one morning and all will be gone. Think about how much equipment you actually need and whether it can all be safely stored inside the vehicle.
3. Keep it simple; I have met people who managed to drive their standard old 2 wheel drives all the way through Africa without problems. Vehicle manufacturers have spent time and money in designing your 4x4 with all its handling characteristics hence keep in mind by lifting your suspension and body you will alter the handling characteristics and steering.
4. Always remember most vehicles in Africa are non 4x4s but they are constantly on the move. A 4x4 can be useful but not essential. Quite often it makes drivers over confident; this can lead to trouble like being bogged on their own in the middle of the Sahara. Besides you do not have to climb over every single rock face and force your vehicle through metre deep mudpools. Just drive around the obstacle!
5. GPS and other electronic gadgets are great toys but electronic gadgets hate 3 things; heat, vibrations and dust. And this is exactly what they are going to get on an overland trip through Africa. Do not rely on them and make sure you are capable of navigating without them. In 2004 while crossing the Sahara desert in Mauritania we tested traditional sun navigation, compass and GPS. While climbing sand dunes the GPS had us positioned 30kms out to sea - we couldn't even see the sea from where we were! The sun won, compass came 2nd and GPS 3rd! Here is a tip; have your compass professionally installed by a qualified technician to ensure it is calibrated to your vehicle.
6. The lighter the better. Small engine vehicles consumes less fuel which means you don't have to carry gallons of extra fuel. Heavy vehicles are more likely to get stuck in soft sand or mud. Light vehicles handle a lot better and are more fun to drive. In 2006 a mate of ours lead a rally from Paris to Bamako; at the start line he arrived in a standard Nissan Bluebird equipped with a tool box from the supermarket, 2 second hand spare tyres, and 1x20lt jerry can for water. He was the only one to finish in Bamako without getting bogged in the Sahara. All the others had USD$100,000 fully decked out 4x4s (very heavy) and were constantly bogged.
7. Food and Water - unless you are going to spend weeks in the middle of the Sahara there is no need to bring tons of food supplies. There are millions of people who live in Africa and they do eat. In most big cities there are supermarkets for expats and surprisingly you can buy the little luxuries from home i.e. Pringles, parma ham, bacon and cheese. Bottled water can be bought or water can be taken from wells and be boiled or treated with iodine or other water treatments.
8. Paperwork - for all vehicles travelling through Africa on foreign number plates they must have a Carnet de Passage. Obtainable from your Automobile Association. This document is a customs paper to allow you to temporarily import your vehicle into the country. Do not leave home without this document.
9. Latest technology 4x4 vehicles have better power and fuel efficiency but are packed with electronics and high tech turbo chargers. These technologies are unknown in Africa. Chances are something will go wrong and no one can fix it. This can leave you stranded for weeks while waiting for spare parts to be flown in from your home country. Add a few extra days, bribes, import duties, stamp fees and nervs to get them cleared through local customs.
10. Never travel at night. An area that is totally safe during the day can turn into bandit country at night. Local vehicles tend to have no or faulty lights, trucks travelling at low speed, donkeys, cyclists and wild life are all over the road. Travelling at night can easily turn into a suicide mission. The more basic it is the less that can go wrong. You want to enjoy the trip and experience Africa instead of spending half of your time fixing your vehicle and all your gadgets. Surely you can survive without the 12 volt hair dryer that plugs into the cigarette lighter.
Africa is an amazing continent and with a bit of know-how and common sense anyone can take The Long Way Down.
