A transmission flush generally takes about 45 minutes to an hour.

A transmission flush is a process of cleaning out the fluid and debris from your car’s transmission. This is done by running a series of fluids through the system to flush out all of the old fluid and any debris that may be stuck in the system. Depending on the severity of the build-up, a transmission flush can take anywhere from 30 minutes to a few hours. If your transmission is severely dirty, it may take a few flushes to completely clean it out.

What Is Transmission Fluid?

Transmission fluid is the liquid that helps to cool and lubricate the moving parts of your transmission. Over time, transmission fluid can become dirty and may need to be changed.
When to Change Transmission Fluid
How often you need to change your transmission fluid will depend on your car and driving habits. In general, it’s a good idea to change your transmission fluid every 30,000 miles or every 2 years, whichever comes first.
If you do a lot of stop-and-go driving or live in a hot climate, you may need to change your transmission fluid more often. Conversely, if you drive mostly on highways or in cooler climates, you may be able to go longer between changes.
The best way to know for sure is to consult your car’s owner’s manual. It will have specific recommendations for your make and model.
How to Change Transmission Fluid
Changing your transmission fluid is generally a pretty simple process. Here’s a step-by-step guide:
1. Park your car on a level surface and put it in neutral.
2. Pop the hood and locate the transmission fluid dipstick.
3. Pull out the dipstick and wipe it clean with a rag.
4. Insert the dipstick all the way back in and then pull it out again to check the fluid level.
5. If the fluid level is low, locate the transmission fluid fill hole.
6. Remove the fill plug and check for debris. If the area around the fill plug is clean, proceed to the next step. If it’s dirty, you may need to have your transmission serviced.
7. Slowly add transmission fluid to the fill hole until the fluid reaches the “full” line on the dipstick.
8. Replace the fill plug and close the hood.

That’s it! You’ve successfully changed your transmission fluid. Now you can hit the road with the peace of mind that your transmission is properly lubricated and cooled.

How Often Should I Change My Transmission Fluid?

You should change your transmission fluid every 30,000 miles.
If you have an automatic transmission, it’s important to change your transmission fluid according to the manufacturer’s maintenance schedule. Many automakers say to change transmission fluid at 100,000 miles or after 10 years, whichever comes first.

If you have a manual transmission, it’s generally recommended that you change your transmission fluid every 30,000 to 60,000 miles.

Here’s a step-by-step guide to changing your transmission fluid:

1. Warm up your car. Transmission fluid flows more easily when it’s warm, so it’s best to change it after you’ve driven your car for a while.

2. Locate the dipstick. The dipstick is usually located near the back of the engine, and it has a loop or handle at the end.

3. Pull out the dipstick and wipe it clean. Then reinsert the dipstick and pull it out again to check the fluid level.

4. If the fluid level is low, add transmission fluid. You can usually find transmission fluid next to the motor oil at your local auto parts store.

5. Replace the dipstick and close the hood.

Here’s a real-life example:

I have a 2014 Honda Accord with an automatic transmission, and the Honda maintenance schedule says to change the transmission fluid at 100,000 miles. I hit 100,000 miles last month, so I took my car to my mechanic and had the transmission fluid changed.

What Are The Symptoms Of A Dirty Transmission?

The symptoms of a dirty transmission are a loss of power, gears slipping, and the transmission overheating.
A dirty transmission can cause a number of problems for your car. The most common symptom is a loss of power while driving. The engine may rev up, but the car won’t move as quickly as it should. This can be dangerous if you’re trying to merge onto a highway or pass another car.

Other symptoms of a dirty transmission include:

-Grinding or shaking when shifting gears

– gears that slip or feel mushy

– a burning smell coming from the engine

– fluid leaks

– check engine light is on

If you notice any of these symptoms, it’s important to take your car to a mechanic right away. A dirty transmission can cause serious damage to your car if it’s not fixed.

For example, last week my car started making a grinding noise when I shifted gears. I took it to the mechanic and they told me that my transmission was dirty and needed to be flushed. If I had waited any longer, the damage could have been much worse.

If you think your transmission might be dirty, don’t wait to get it checked out. It’s better to be safe than sorry!

What Are The Symptoms Of A Failing Transmission?

The symptoms of a failing transmission are a burning smell, a grinding noise, and difficulty shifting gears.
A failing transmission can have many different symptoms. Some of the most common symptoms are:

1. The transmission starts to slip. This means that the transmission is not engaging properly and is starting to slip out of gear.

2. The transmission is making strange noises. This could be grinding, whining, or other strange noises that you wouldn’t normally hear.

3. The transmission is leaking fluid. This is a sure sign that something is wrong and should be checked out immediately.

4. The transmission is not shifting gears properly. This could be delayed shifting, hard shifting, or no shifting at all.

If you notice any of these symptoms, it’s important to have your transmission checked out by a professional as soon as possible. Ignoring these symptoms could lead to more serious problems down the road.


What Are The Symptoms Of A Low Transmission Fluid Level?

The most common symptom of a low transmission fluid level is a delay in the engagement of the transmission when shifting from park to drive (or drive to reverse). Another common symptom is the transmission slipping out of gear while driving.

How Do I Check My Transmission Fluid Level?

To check the transmission fluid level, find the dipstick (usually labeled “Tran”), and pull it out. Wipe the dipstick off with a clean rag, then reinsert it and pull it out again. The fluid level should be at or just below the “Full” mark on the dipstick. If it’s low, add transmission fluid until it reaches that level.

What Are The Signs Of A Transmission Fluid Leak?

There are a few signs of a transmission fluid leak:

1. You may see a red or pink fluid on the ground where your car is parked.

2. Your transmission may start to slip or feel less responsive.

3. Your car may start to make strange noises, like whining or grinding.

4. Your transmission fluid level may drop noticeably.

How Do I Fix A Transmission Fluid Leak?

There are a few ways to fix a transmission fluid leak. The first is to simply add more transmission fluid to your car. This will only work if the leak is small and the fluid level is low. If the leak is bigger, you will need to find the source of the leak and fix it. This could involve replacing a seal or gasket. You may be able to do this yourself if you are handy with car repairs. If not, you will need to take it to a mechanic.

How Can I Prevent Transmission Fluid Leaks?

The best way to prevent transmission fluid leaks is to have the transmission system serviced regularly by a qualified technician. Transmission fluid leaks can also be prevented by ensuring that the transmission system is properly sealed and that there are no cracks or holes in the system through which fluid can escape.


A transmission flush should take around 1-2 hours.
