The Oil Changers Guide To Caring For Your Transmission
Posted 18 February, 2014 2:29 PM
Most cars and trucks have automatic transmissions, yet a lot of Dunedin motorists only have a fuzzy understanding about what a transmission does. Think back to the last time you rode a bike in Dunedin. You started out in a lower gear and shifted to higher gears as you went faster. Down shift for hills, stuff like that. Think of your legs as the engine – there’s an ideal speed you can pedal and you change gears to leverage the work you’re doing.
Lower gears for power on hills or for starting out. Higher gears for more speed. That’s what the automatic transmission does – it automatically starts in lower gears and shifts up to higher gears to go faster on New Zealand expressways. And automatically shifts back down to climb Dunedin hills, pass or start up again.
Cars automatic transmissions have certainly gotten more sophisticated in recent years. They have more speeds than before: the base is four speeds, five is very common.
At Oil Changers, we routinely service transmissions with six speeds and several have seven or even eight speeds. As you can imagine, this means more parts. Any they all have to fit into roughly the same space.
Transmissions are computer controlled these days, with some high end transmissions having two or three computers. Transmissions are engineered to last. But they are also engineered to tighter tolerances. If a portion of the transmission is starved for lubrication, it can lead to failure.
Not enough fluid can starve the transmission or dirty transmission fluid can clog small passages in the transmission, then the lubricant is blocked and can’t get to all the parts to protect them, so they wear out prematurely. The technicians at Oil Changers see far too many transmissions that needlessly failed due to neglect.
And, as you can imagine, repairing one of these new transmissions at any Christchurch service center can be quite costly. That’s why auto makers have a schedule for how often you should change the fluid and what type of fluid to use.
It’s really important for Dunedin motorists to carefully follow the manufacturer’s transmission service schedule.
At Oil Changers in Christchurch, we hope you never become shiftless in Dunedin because you didn’t take care of your transmission.

Let's talk about transmission service. It can be easy to forget about getting your transmission serviced because it doesn't need it very often. It's easy to remember to change the engine oil - you know, every 7,500 - 15,000 kilometers. But proper transmission servicing keeps your car running smoothly and helps you avoid costly repairs down the road.
The transmission undergoes a lot of stress. The grit you see in used transmission fluid is actually bits of metal that wear off the gears in the transmission. In addition to that, the transmission operates at very high temperatures. Usually it's 100 to 150 degrees higher than engine temperatures. Those high temperatures eventually cause the transmission fluid to start to break down and loose efficiency.
As the fluid gets older, it gets gritty and doesn't lubricate and cool the transmission as well - leading to even more wear. The fluid can actually get sludgy and plug up the maze of fluid passages inside the transmission. At best, your transmission won't operate smoothly. At worse, it could lead to costly damage.
When your transmission is running properly, it transfers more power from your engine to the drive wheels, and improves fuel economy. That's why manufacturers recommend changing your transmission fluid at regular intervals. Your owner's manual has a schedule for transmission service and, of course, your service center can tell you what the manufacturer recommends.
Hot and dusty conditions; towing, hauling, stop and go conditions and jack rabbit starts all increase the load on the transmission and its internal temperature. That means you need to change the fluid more often. A good rule of thumb is every 55,000 - 90,000 kilometers or two years. If your manufacturer suggests more frequent intervals or if you're driving under severe service conditions, you will need to change it more often.
Most service centers have the ability to perform a transmission service while you wait and the cost is quite reasonable. It's downright cheap when you think about how much a major transmission repair can cost! Your service technician will know the right type of transmission fluid to use. If it's getting to be time to have your transmission serviced, do your car a favor and have it done. If not this time, then on your next service stop.
Smooth Shifting : Transmission Service

So you have some exciting plans for the weekend. You’re going to take some of your friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. But you want to make sure that your Cars maintenance is up to date.
Think about it – heavy traffic on the way out of town. There’s hilly terrain as you get to the lake. Some dirt roads – and its going to be pretty hot this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.
Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the local New Zealand lake for you is really severe duty for your transmission.
It’s important to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced at Oil Changers on schedule to make sure it runs efficiently.
An automatic transmission contains a maze of passages through which the fluid has to pass to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems.
Neglect your transmission for too long, and it can fail. You really don’t want to pay for a major transmission repair.
This reminds us of how much of our driving around New Zealand, is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold weather. Dusty roads and city driving around New Zealand add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.
