The Dexron III transmission fluid is a synthetic blend. It is a long lasting, but will not give extended drain intervals like some of the newer synthetics that are now available on the market.

It has passed the GM Total Base Number (TBN) requirements of 9.0 mg KOH / gm.

Dexron 3 has been tested and passed the GM Total Base Number (TBN) requirements of 9.0 mg KOH / gm. TBN is a measure of a lubricant’s ability to counteract acids that form during operation; it is measured by the amount of KOH required to neutralize the acid in the lubricant.

Dexron III was introduced by GM in 1967 to replace Dexron II.

Dexron III was introduced by GM in 1967 to replace Dexron II. It is the first ATF to be manufactured using synthetic base oil and contains additives to minimize wear on synchronizers, clutches and bands.

Dexron III is a Gear Lube and Type A, Suffix A Automatic Transmission Fluid (ATF). It is acceptable for use in vehicles equipped with both manual transmissions or automatic transmissions having electronic controls that require ATF.

Dexron 3 Transmission Fluid is a fluid that lubricates your transmission. Transmission fluid improves the performance of your vehicle by reducing friction between the gears and bearings in your transmission. The more efficiently you can transfer power from one gear to another, the faster your car will be able to operate.

Dexron 3 Transmission Fluid is a fluid that lubricates your transmission. The transmission is an integral part of the vehicle’s drivetrain, which includes the engine, axle, and gearbox. It allows you to change gears manually when you accelerate or brake while driving. When you press down on the gas pedal and feel it go up against resistance as if there was another force resisting it back in order for it to move forward—that’s your transmission working as expected!

The Dexron 3 Transmission Fluid is a synthetic blend that helps keep your transmission running smoothly all year round regardless of weather conditions or mileage driven per day/week/month/year (you get our drift). This makes sure that all parts inside are kept lubricated so they don’t wear out prematurely due to friction caused by metal-to-metal contact without having enough lubrication present during operation time periods; this way everything works together properly which results in better fuel efficiency too—talk about win-win situations!

Your transmission is one of the more expensive parts of your car, so it is advisable to use Dexron 3 Transmission Fluid if you have a transmission that requires this fluid.

Transmission fluid is an important part of your car. It keeps all of the moving parts working properly and lubricated as they go through their cycles. The different types of transmission fluids vary in their properties, but Dexron 3 has been determined to be the best for most passenger cars and light trucks in general. This type of transmission fluid has been found to provide optimal performance at various temperatures and pressures, which mean it will work well under any circumstances you might encounter when driving around town or on long road trips out into nature.

Although there are other cheaper options available on the market today—including those that claim they offer better performance than Dexron 3—you should know that these are not necessarily true because they don’t meet GM standards for all GM vehicles manufactured after 1996 (and some before).

Dexron III was introduced in 1996 as the official replacement for Dexron II.

Dexron III was introduced in 1996 as the official replacement for Dexron II. The two fluids are identical and should be used interchangeably. Dexron III is a transmission fluid designed to provide smooth shifting and improved wear protection for automatic transmissions, power steering systems and torque converters.

GM came out with over time.

Dexron III fluid was first used in GM transmissions, and it has been in production since 1965. Dexron III fluid is an enhanced version of the original Dexron formula, and one of its primary improvements is that it does not break down as quickly under high temperatures. This makes it ideal for use in transmissions with a higher number of gears or that are shifting more often.

You’ll probably want to do it every 90 days.

You should change your Dexron III transmission fluid every 90 days. The best time to check the fluid level is before you drive. If you don’t check it, you could be driving around with a low fluid level and not knowing it. This can lead to overheating and serious damage to the transmission if not addressed quickly.

Flush and replace your Dexron III transmission fluid once a year (more often if necessary) if you have more than 50,000 miles on your vehicle or tow any kind of load regularly. Read Also : How to Change Transmission Fluid

Be sure to test for leaks before spending money to replace the fluid.

If you suspect that a Dexron 3 transmission fluid leak may be present, the first step is to inspect your vehicle for signs of leakage. An easy way to do this is by checking the fluid level in your transmission:


Overall, Dexron III is a great transmission fluid to use if your vehicle requires this type of transmission. It offers many advantages over other fluids, such as being able to withstand high temperatures without breaking down and providing better lubrication than other types of oils. However, there are some drawbacks that need to be considered before deciding whether or not it’s right for your vehicle: If you have an older car that requires Dexron II (or earlier), then changing over may cause problems — especially if the owner’s manual does not specify which type should be used instead. Also consider the cost difference between using Dexron III versus another type like regular oil; while there may be no difference in performance between them (or even less wear), it could save money by not having to purchase new parts every time they break down due to excessive wear caused by friction across surfaces within the engine block itself (which would eventually happen with either choice).
