Why You Should Never flush your transmission fluid?

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.

Are transmission flushes really necessary?

Much like oil changes, transmission flushes should be performed every so often to maintain the transmission system, which you cannot drive without. If you bring your car in so our technicians can complete this service, your vehicle can stay running at its best.

Does flushing a transmission cause problems?

And some people warn against performing a flush on a transmission using old, dirty fluid. The flushing procedure may cause some fluid to move in the opposite direction of normal flow due to eddy currents, which may increase the risk of dislodging debris and causing it to settle somewhere it shouldn't.

Does a transmission flush do more harm than good?

Though service advisors and mechanics may tell you otherwise, fluid flushes are almost always unnecessary and can do much more harm than good.

When should you not flush your transmission?

The manufacturer's maintenance schedule for many automatic transmissions doesn't call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and that it should be done at least every 50,000 miles.

Why You Should NEVER FLUSH YOUR TRANSMISSION FLUID!!

Is it better to flush or drain transmission fluid?

In any case, choosing a fluid flush or a drain and refill is better than not performing any kind of maintenance on your transmission. With some vehicles, a fluid flush or change is irrelevant as they may have a sealed transmission. Refer to your owner's manual to be sure.

What happens if you never change transmission fluid?

Transmission Overheats.

Changing your transmission fluid periodically will increase the lifespan of your transmission. On the other hand, if you never change it, you will have dirty and grimy fluid that will fail to lubricate and disperse heat very well.

Is it OK to change transmission fluid after 100k miles?

Do You Need to Have the Transmission Fluid Changed? The simple answer is yes. But service intervals for new vehicles can exceed 100,000 miles before this needs to be done.

Will changing transmission fluid help hard shifting?

When the temperature drops, transmission fluids with poor cold-flow properties can thicken and cause elongated and hard shifts until the fluid has warmed up enough to flow properly. Switching to a high-quality synthetic transmission fluid will help.

What are the benefits of a transmission flush?

It cleans sludge, gum, and varnish. It also removes harmful deposits and dirty oxidized fluid. It improves shifting and reduces transmission heat. The biggest benefit is it extends the life of your transmission making it less likely for an avoidable expense like premature transmission replacement.

What is the average cost for a transmission flush?

Average Cost and Factors

The typical price range for a transmission flush is $125 to $250 – approximately twice as much as a fluid change due to the additional fluid required (12-22 quarts instead of 5-7 quarts) to completely replace the old fluid. The average you can expect to pay is $150 for the full service.

Why does car jerk when changing gears?

Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.

What does Black transmission fluid mean?

The reason why transmission fluid changes from bright red to brown to black as it ages is that is it oxidizing. Oxidation is bad for transmission fluid. Dark brown or black transmission fluid is dirty and incapable of lubricating the hundreds of transmission parts. It will cause damage if you don't have it changed.

What does it mean when your transmission fluid is brown?

Brown and dark brown hues indicate that the transmission fluid is no longer viscous and it is oxidizing. Oxidizing means the fluid is filling with air bubbles and is unable to do its job. Change your transmission fluid right away when it's this color.

How many miles should a transmission last?

Without service and maintenance, some transmissions can fail in as little as 100,000 miles. If you drive around 10-15,000 miles a year, your transmission could be down for the count in seven years! With care and service, transmissions can last 300,000 miles or more.

How long should transmission fluid last?

If fluid temperatures can be held to 175 degrees F., ATF will last almost indefinitely -- say up to 100,000 miles. But if the fluid temperature goes much higher, the life of the fluid begins to plummet. The problem is even normal driving can push fluid temperatures well beyond safe limits.

Can you mix old and new transmission fluid?

This fluid starts to lose its standard properties and should be changed to keep the transmission parts and its performance at its peak. Mixing old and news fluids wont give you the ideal viscosity and the reduces the performance of the transmission system.

How do I know if my transmission fluid is bad?

What does Milky transmission fluid mean?

The milky substance you are seeing on the transmission dipstick is a result of cross-contaminated coolant and transmission fluid. More than likely, your radiator has failed which has allowed coolant to enter the transmission system.

What color is healthy transmission fluid?

Healthy transmission fluid should be relatively clear or pink in color. If your transmission fluid is deep red or brown, your transmission fluid is old and most likely causing extra damage within your transmission.

Will flushing transmission help with slipping?

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.

Why does my transmission slip when I accelerate?

Transmission gears wear out and start slipping.

Worn or rounded out gears don't properly link together so this can cause a bumpy shift and slippage as you accelerate and drive.

What does a slipping transmission feel like?

One of the most common transmission problems that you can encounter is a slipping transmission. This means that it is not shifting smoothly from gear to gear or that it is not staying fully in gear as you drive.

How long does a transmission flush take?

A trained mechanic can perform a simple transmission flush in three to four hours using a commercial flushing machine or pump inlet. A transmission fluid change takes just about 30 minutes.

How much does Jiffy Lube charge for transmission flush?

On average, transmission flush at Jiffy Lube costs about $150 with average prices ranging from $100 to $200 in the US for 2022.
