7 Things To Consider When Choosing The Best Transmission Fluid For 4l60e
Importantly, proper transmission fluid may make a significant impact on the performance of your vehicle. Whether you drive an automatic or manual, the wrong one will wear out parts and cause more problems than they solve! But not all fluids are created equal- there are cheap knockoffs that don’t work.
So do yourself (and potentially others) a favor: get a high-quality product. Because there are so many different transmission fluids available, you may be wondering which one is the most suitable for your 4L60E. Well, luckily we have compiled some important information on how to choose wisely!

1. Natural Or Synthetic?
Synthetic formulations have better temperature performance compared to natural options, as well as improved oxidations and wear resistance. When it comes down to the transmission fluid choice for your car or truck, you already know what type of fuel they’ll use –so why not choose wisely?
That’s where synthetic versions come into play; these fluids are made out of polyester-based chemicals which give them an edge over their counterparts. Especially, when dealing with high heat levels (which can be caused by long periods without switching).
2. Type Of Transmission
The type of transmission fluid your car needs will depend on the kind you have. If it’s an automatic, then a different class or grade for transmission oil is necessary than what’s used by manual drivers.
As because they don’t need as much power from their gears and clutches to get up hills with momentum alone. And that can cause them not to have enough torque at slower speeds.
3. Usability
You may want to double-check that your car’s manual is current before heading out. Each vehicle system has different fluid recommendations from manufacturers, so check carefully and make sure you have all of the appropriate fluids with you.
4. Additives
Additives are important for improving the performance and durability of transmissions. Too many unnecessary ingredients can affect how well a particular product works for you and cause more harm than good in some cases!
5. API Rating
To ensure the highest level of quality for their fluids, American Petroleum Institute rates them into a basic category. They specifically go with GL-1 up until GL-5 which is usually enough for most applications.
However, there are always some exceptions if you want something more specific like say an engine that needs only specific grades or types on hand at any given time.
A most important note here: while API does have different categories ranging from GEL 1 through 5 depending upon what type and severity of system failure we are trying to protect against.
6. Container
Purchasing small quantities can be costly. If you want to get your hands on quality 4L60E fluids, make sure that the purchase is large enough and won’t go obsolete quickly as some other products do. Especially, when it comes down to their original size or bottle capacity.
7. Surface Lubrication
One important task concerning the use of ATF is to keep all moving parts lubed. Without proper surface lubrication, metal-on-metal friction will occur which can cause damage and wear over time for both internal components as well external systems.
people also ask (FAQs)
What Kind Of Transmission Is A 4l60e?
Undoubtedly, the 4L60-E is considered by many to be the finest & automatic transmission ever produced. Plus, longitudinally positioned, a four-speed overdrive was first introduced in 1982 and remains one of Detroit’s most popular transmissions today.
How To Mixdexron-III And Dexron VI?
Yes you can mix dexron-iii and dexron VI. DEXRON-VI is a better choice for automatic transmission fluids because it can be used following any measurement. It also works well with older models of vehicles equipped with an automatic gearbox and previous versions of this type of synthetic blend are compatible too!
Is Transmission Fluid The Same As Power Steering Fluid?
Power steering fluid and transmission fluid are both types of hydraulic oils. However, power steering is not identical to automatic transmission (ATF) because it contains friction modifiers that will clean out dirt from under your car but damage the valves inside.
Can You Mix Old And New Transmission Fluid?
Your transmission needs to be maintained with the right fluids because it will not work properly when you mix old and new. The difference in viscosity can affect how smoothly gears shift and reduce the performance of both automatic transmissions as well as manual ones.
What Happens If You Put The Wrong Transmission Fluid?
Transmission fluid is a finite resource that requires special care. If you use the wrong type, your transmission could overheat or fail due to poor lubrication and fragmented metal on its components.
Is Synthetic Transmission Fluid Better?
A synthetic fluid has the potential to improve the smoothness of your transmission’s functioning. Because of superior engineering, it can better sustain viscosity at any temperature and in all conditions – even when faced by variations within that range!
closing thoughts
With the transmission fluid for 4l60E, shifting gets easier and smoother. It also has been proven to increase gas mileage by up to 2% which can make all the difference when it comes time for your next oil change!
Gear shifting is always difficult, harsh, and unpleasant without transmission fluid for 4L60E on demand. You need to purchase only what you rightfully deserve -the right type of product with satisfaction in mind!
