How Often To Do A Transmission Flush – Is it better to drop the washer or the pan when changing the transmission fluid? Learn the pros and cons of each method.
It depends on what you want to achieve. But first, check your car manufacturer’s owner’s manual to see if it recommends one over the other. Flush the transmission if you want to ensure that almost all of the old transmission fluid is removed.
How Often To Do A Transmission Flush
The benefits of flushing are self-evident: all old, dirty fluid is replaced with fresh, high-quality fluid. And as you can see in the picture, the old fluid is preferable to the new transmission fluid.
Transmission Fluid Change Vs. Flush: Which Is Right For You?
As a result, your transmission should run cooler and receive maximum protection against wear on clutches, gears and bearings.
It should also shift consistently and crisply because the new fluid will provide the correct friction properties (old fluid loses friction properties over time). In fact, a transmission that shifts hard, hesitates, or jerks is sometimes related to worn fluid.
Sludge and other contaminants can build up in the fluid due to the extreme heat that decomposes the fluid. These contaminants circulate throughout the transmission before being trapped in the filter.
Before the filter can safely capture contaminants, they can lodge in the narrow fluid passages inside the valve body, causing poor ride quality.
When Do I Need To Change My Transmission Fluid?
Performing a flush also allows you to use a flush additive to help clean the transmission and remove accumulated sludge and other contaminants more effectively.
First, it is more expensive. And some people warn against flushing the transmission using old, dirty fluid.
A typical washing machine uses hoses connected to transfer cooling lines. It drains the old fluid and keeps it inside the car while refilling the transmission with new fluid.
Unlike a simple pan-drip, the washer cleans out almost all of the old fluid, including the fluid inside the torque converter.
To Flush Or Not To Flush? Car Fluids You Should Really Replace
Because the procedure uses new fluid to perform the flush, additional fluid beyond the final capacity of the transfer is required. Plus, you need extra fluid to fill the washer tank and lines. Some liquid is also used to prime the pump. These additional quartzes are where most of the costs are.
Let’s say you have a small car that takes about eight quarts of transmission fluid, and you’ve had it serviced at the dealer using original equipment manufacturer (OEM) fluid, which costs about $20 per quart. They also replace the transmission filter and pan gasket.
But let’s say you’re riding a RAM* 2500 that takes over 15 liters of transmission fluid. Your cost to clean the transmission can quickly exceed $400.
Depending on the size of the vehicle and whether you contact an independent mechanic or dealer, the cost of a transmission flush can range from $150 to $400.
To Flush Or Not To Flush
Plus, you’ll often see mechanics offering a transmission for around $100 to get you in the door, so keep your eyes peeled for deals. Be aware that these deals always include a limit on the amount of fluid used, so don’t expect to flush the tranny on the RAM 2500 at this price.
Keep in mind that many repair shops and quick lube are particular about the fluids they use in their washers, so it can be difficult to find one that accepts customer-supplied fluids. Washing machines should be cleaned between products to avoid cross-contamination.
If you wash or pan-dip the gearbox, service your transmission periodically to ensure it stays clean and shifts properly.
Again, it depends on the power of the transmission, where the service is performed, the cost of the filter and gaskets, and the cost of the fluid. Since it requires less fluid than a pan-drain transmission, it will cost less.
When To Flush My Transmission Fluid
Here I will go to the well of personal experience. I dropped the pan on top of my old Geo Prizm, * drained about three quarts of fluid and replaced it with AMSOIL Signature Series Synthetic Automatic Transmission Fluid, replaced the filter (the gasket was still good) for about $60.
I might have paid less if I had used AMSOIL OE Synthetic Automatic Transmission Fluid for cars and trucks, but in my opinion the Geo Prizm deserves an over-engineered fluid for towing and hauling.
A pan-drip requires seven liters of fluid and a larger, more expensive filter. They’re not an avid DIYer like me, so take another $100 or so to pay the mechanic, which means their transmission fluid replacement cost will be about $275.
Again, the cost of changing the transmission fluid will vary depending on the size of the vehicle, who performs the service, and the cost of filters and gaskets.
Yes, A Transmission Fluid Change Is Needed (and Here’s Why)
If you do it yourself in a small car, it will cost $50-$75. Pay a dealer to change the fluid in your heavy-duty truck, and plan on paying $200-$300, especially if you’re using OEM fluid.
Although it reduces the risk of old, dirty fluid washing through the transmission, pan-drip also has its downsides.
If you haven’t been under your car in a long time, plan to encounter rusted, stuck bolts if you drive in wet, snowy conditions.
Don’t be surprised if you crack a spot or two when trying to remove/reinstall the splash guard.
How To Change Your Transmission Fluid
This allows you to easily and cleanly drain some fluid from the transmission without the hassle of removing the pot. Again, you only get one-third to one-half of the liquid.
After that, you can drive the car for a while, drain the fluid and change it again. Do this about 3 times and you will remove most of the old fluid and perform a sort of poor man’s transmission fluid flush.
Bottom Line: Get a professional and clean the transmission for best results and least hassle (unless your vehicle manufacturer specifically warns against this in the owner’s manual), especially if the transmission has been roughed up and has no service description.
However, if you have reservations about flushing the debris or keeping the transmission well maintained, a series of pan-drops also work well. With summer winding down, now is the perfect time to prepare your car for fall and winter weather. . For most cars, this will include routine maintenance such as changing the engine oil, checking your battery, making sure your tires are at the correct tire pressure (PSI), and even giving your car a much-needed deep clean.
Transmission Flush Vs Fluid Change: Which Is Better?
But while these are common maintenance items that most people do out of habit, there are things that many car owners can’t do, like changing your transmission fluid.
In a car or truck, the transmission is a very important component of the vehicle’s powertrain that converts the energy generated by the engine into the torque needed to move the drive wheels. This is because the transmission adjusts the gear ratio between the engine and drive wheels, shifting properly when your car slows down or accelerates.
In simpler terms, the transmission ensures that the right amount of power is transferred to your wheels to drive at a certain speed. That’s why transmissions have gears. Downshifts are used to make sure your car or truck has the power to move the vehicle forward from a dead stop or low speed. For any vehicle, where less torque and power is required, you will use higher gears to travel at higher speeds.
Transmissions can come in several different forms, with manual and automatic transmissions being the most popular options. A manual transmission will require you to shift gears manually in order to function properly. This is done using a shifter, clutch and flywheel. On the other hand, automatic transmissions are the most common because they simply need to be put in “drive” to enjoy the car while changing gears automatically.
Clogged Transmission Filter? Symptoms Of A Clogged Filter & Cost To Fix
Transmission fluid works much like any other fluid in your vehicle in that it provides lubrication for the moving parts in your transmission. Without transmission fluid, your transmission will run very hot due to the friction of the moving parts. This will cause your transmission to malfunction, or worse, complete transmission failure, meaning you’ll need a whole new transmission that could cost you thousands of dollars. Even driving with low transmission fluid levels or old fluid that hasn’t been changed in a while can potentially damage your vehicle.
In general, the main job of transmission fluid in manual transmissions is to lubricate internal parts and keep the transmission cool. Although a manual transmission has fewer moving parts, it still requires the use of fluid to lubricate the parts.
In automatic transmissions, the fluid does the same thing as in a manual transmission, but it also provides hydraulic pressure and friction for the internal components to function properly. Thanks to its sophisticated design, the automatic transmission uses hydraulic pressure to shift gears easily and automatically. This is one of the reasons why you don’t feel the transmission shift while driving an automatic vehicle.
However, while transmission fluid works practically the same in automatic and manual transmissions, they don’t always use the same fluid. For example, some automakers of automatic or continuously variable transmission (CVT) vehicles, such as Honda, may require a specific automatic transmission fluid. If you have, you can damage your car
