Is it bad to drain transmission fluid?
If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.
Is it better to flush or change transmission fluid?
A transmission fluid change will help to restore your system to good working order and is the cheaper option. It is also a relatively simple task that can be undertaken by vehicle owners. A transmission fluid flush is more costly, but will replace all of the fluid and any contaminants that have built up in the system.
Can a transmission flush hurt your transmission?
Almost every car manufacturer recommends against using transmission flushing chemicals, and most will void your transmission warranty if they can prove these chemicals are being used. These chemicals can damage your transmission, which is why most automakers recommend against them.
How often drain and fill transmission fluid?
Nothing prolongs vehicle life more than regular fluid changes. In automatic transmissions/transaxles, the recommended service interval is about every 30,000 miles or 30 months. (Check your owner’s manual or service manual for your car’s specifics.)
Will changing transmission fluid help shifting?
If you catch a shifting issue very early, a transmission fluid flush can sometimes fix shifting issues. The fresh fluid helps clutch discs and steel discs bond and hold without slipping. The seal conditioners in the new fluid help soften the clutch piston lip seals so they seal better.
How do you drain and fill transmission fluid?
With a drain and fill, you are only removing about half of the fluid from the transmission via the drain bolt, replacing it, and then adding the same amount of new fluid that came out. Then, drive the car for a day or two, drain the fluid again, and replace with new fluid. The idea here is that you’re weening the car off the old fluid.
What is a transmission fluid flush?
When doing a transmission fluid flush, the concept is to get all of the old fluid out at once and simply replace it with new fluid. With a drain and fill, you are only removing about half of the fluid from the transmission via the drain bolt, replacing it, and then adding the same amount of new fluid that came out.
How many times can you change transmission fluid in a car?
Again, though, you only get a third to half the fluid out. You can then drive the vehicle for a while, drain the fluid and change it again. Do this 2-3 times and you’ll remove most of the old fluid and perform a sort of poor-man’s transmission fluid flush.
What is the difference between a transmission flush and a pan drop?
Unlike a simple pan drop, a flushing machine removes just about all the old fluid, including the fluid inside the torque converter. Since the procedure uses new fluid to perform the flush, it requires several quarts of new fluid beyond the transmission’s final capacity. Those extra quarts are where most of the added cost lies.
