Fluid Change


As part of a preventive maintenance program a car with an automatic transmission, the ATF needs to be changed every so many thousand kilometers. Some have asked if they could change it earlier… yes, you can. If the prescribed mileage, say 60,000 kilometers, is when to change your ATF, it would take you three years to attain that. So it would be all right to change the ATF at an earlier time. Some would even recommend changing it yearly. To some, they may just travel a short distance to get to their destination but they spend a good amount of time in traffic, then it’s almost be the same as traveling fast on the highway. When you are in traffic, there is a possibility that your ATF can get to hot. The heat from the exhaust of other cars and limited airflow can raise the temp of your fluids.

If ever you decide to change you ATF, just make sure that you drain the old ATF completely. You could this by raising the driving wheels of your car and draining the ATF. Then refilling it and putting it through the gears and running it while the driving wheels are up. Drain it a couple of times to make sure all the old fluid is out. Or you could bring to a shop that has a dialysis machine for the transmission. Make life easier for yourself. Make sure to use the proper spec of ATF and clean or replace the filter. You could also use a flushing solution to remove any gunk inside the transmission. There are also additives you could add to help keep the ATF from breaking down.

For those with manual transmissions, you would also need to change the oils. Changing the fluid in manual transmissions is mostly forgotten. It’s the clutch that is usually the concern of most car owners. Again, don’t scrimp on the kind of gear that you use. The manual transmission can also breakdown and can be also expensive to fix. Since we’re on the drive train topic, the fluid of the differential shouldn’t be forgotten. Like the manual transmission, it too is neglected. Taken cared of properly, the manual transmission and the differential can last you the life of your car. As long as they are well cared for and not abused.

On another note, if you are experiencing failure of the rubber parts inside your brake master or clutch master, try switching brake fluid brands. It is possible that the rubber components are reacting to the brake fluid you are using. Assuming you have eliminated the other possible causes of the parts failure. Each manufacturer of brake components have different recipes for their rubber products. So does the brake fluid manufacturer. Although they all have to meet specific requirements, not all react the same in actual usage. Even if you use OEM (original equipment manufacturer) parts and fluids. That is why they keep on upgrading their standards.

If the problem persists and you hear it is happening to other owners with the same make and model, then it would be possible the issue is a design problem. Either by the design engineers or on the manufacturing side. Don’t worry, these things do happen. If it is a design problem, you could ask the dealer if they are aware of the problem. If they acknowledge the problem, chances are they would have a solution for it. If they are not aware of the problem and they can’t help, try looking for a different brand. Sometimes, the part may look the same but in the manner it was manufactured could make a difference.
