Modern transmissions contain many electronic and mechanical components. The mechanical parts require a special lubricating fluid. Usually, when experiencing transmission problems, the issue lies with the fluid. When it’s time for maintenance, do you know the difference between a transmission flush vs change?
Common Signs Your Vehicle Transmission Needs Attention
Typically, you’ll know you have a bad part or degraded automatic transmission fluid by the following signs:
- Transmission Slipping
As you drive, your automatic transmission shifts gears based on your speed. A slipping transmission will change gears and sometimes switch into neutral without altering speed.
Comparatively, the same thing can happen in a manual transmission. With a manual, you use the clutch to switch gears at certain speeds. However, a worn-out clutch will cause unintended shifting gears.
- Unusual Noises
Automatic transmission fluid lubricates and provides hydraulic pressure. Old, dirty fluid can’t cool or lubricate parts properly. As friction increases, metal parts expand. Then, metal can grind against metal causing unusual sounds.
- Overheating Engine
Although separate systems, the transmission and engine interconnect through the cooling system. Accordingly, when the transmission fluid surpasses the optimal operating range, it will cause the engine to overheat.
- Delayed/Difficulty Shifting Gears
Over time, transmission fluid will break down and degrade losing its protective properties. As it chemically deteriorates, it forms sludge and varnish increasing friction between parts. Thus, you may experience delays or difficulty in shifting gears.
- Illuminated Dashboard Indicator Light
Manufacturers equip modern vehicles with dashboard indicator lights that light up when something is wrong. Usually, a transmission indicator light looks like a gear with an exclamation mark or thermometer inside. It will illuminate for a variety of reasons including low fluid levels, overheating, or internal component failure. Your check engine light may illuminate as well.
Transmission Fluid Change Vs Flush
Unfortunately, according to one survey, about 92% of car owners put off maintenance longer than they should. Yet, failing to perform routine maintenance can shorten the life of your transmission. Furthermore, a vehicle transmission rebuild or replacement is one of the most expensive car repairs.
Moreover, regularly replacing the fluid is the best way to keep your transmission healthy. When performing this service, you have 2 choices:
Fluid Change
Typically, performing an automatic transmission fluid change is a relatively simple, but messy task involving a drain and fill procedure. You’ll need to raise the car on ramps to access the transmission pan. Once you locate the pan, loosen the bolts. Since old fluid is toxic, carefully collect it and take it to a hazardous-waste accepting location.
Next, clean the pan, replacing both the gasket and filter. Then, reattach the pan to your vehicle. Finally, add fresh transmission fluid.
Often, many people opt for this service because it’s cheaper than a flush. However, this method only removes about ⅓ to ½ of the total fluid. Thus, some of the old, dirty fluid remains in the system.
Flush
The other way to replace your transmission fluid is with a flush. This process requires the use of a high-pressure flushing machine with a cleaning agent. Unlike a change, a flush removes almost all of the old fluid.
Although a flush leaves none of the old fluid behind, it may loosen deposits without removing them from the system. These small particles can become lodged in the narrow internal passages leading to other transmission problems. Plus, it’s more expensive than simply draining and refilling the fluid.
Transmission Flush Vs Change FAQs
Do you still have questions about the best way to care for your transmission? Below we answer a few commonly asked questions about transmission flush vs change. If you have any others, call Havoline® Xpress Lube of Kernersville at 336-904-6319.
Which Is Better For My Car, A Transmission Flush Or Change?
Since experts don’t agree on the best option, it can be hard to decide which one to choose. Thus, it’s best to talk to a trusted automotive expert, like Xpress Lube.
However, if you don’t flush the system, you’ll have to repeat the process every 30,000 miles. With only about ½ of the fluid replaced, the remaining will contaminate the new fluid requiring more frequent changing.
What Is The Cost Comparison Of A Transmission Flush Vs Change?
Unfortunately, without knowing the make, model, and year of your vehicle, it’s only possible to give a generalized price. The type of your transmission, manual or automatic is one factor affecting price. Another is the amount of fluid your car requires. Typically, you can expect to pay anywhere from $80 to $250.
Can I Drive With A Malfunctioning Transmission?
While it’s possible to drive with a bad transmission, it’s very dangerous to do so. Often, this system can quickly slip from usable to broken. Then your car may become harder to control. Moreover, an improperly working transmission will stress other components causing additional damage.
