What Is Transmission Additive?
The transmission system is one of the most crucial parts of your vehicle. It works in association with your vehicle’s engine, and it determines the performance of your vehicle at different speeds. Just like the engine needs motor oil, the transmission system needs transmission fluid for lubrication. With proper lubrication and due to lack of treatment of the transmission fluid, the transmission system will get overheated due to friction and the performance of the vehicle will gradually go down. If the situation continues, the transmission system will stop working and repairing will lead to spending thousands of dollars.

Transmission Additive — The Benefits
The following are the various benefits of using a transmission additive with transmission fluid.
- Minimize Sludge: With time, the transmission fluids tend to get thick. There are various dirt and contaminants mix with it, and soon, sludge and varnish are formed. This will prevent the parts from moving smoothly. A transmission additive can prevent the formation and let your transmission fluid work the best.
- Reduce Wearing: No matter how premium transmission fluid you use, as it starts to age, it gets thicker. The thicker it gets, the more friction begins to happen among parts in the transmission. A good transmission additive prevents that by keeping the transmission fluid soft and healthy. Therefore, it can keep up the excellent performance of the transmission and prevent wearing on parts. Consequently, you can save a lot in repairing, and it also reduces the noise and shudder generated.
Apart from that, it extends the lifetime of the transmission system, and let the vehicle operation at the peak of its performance indirectly.
How Does Transmission Additive Work?
Basically, your transmission needs fluid/additive to protect the gears and bearings from wear and tear. The transmission allows you to shift gears fluidly without strain, and it always works hard which is why additive is important. Some products even provide improvements in anti-shudder durability which increases the performance of the transmission which is great.
That is why you have to change the fluid once in a while to experience less transmission mechanical and component breakdown. You can either fully replace the fluid or just add the fluid to reduce the cost. The price range from $10 to above $20 depends on the brand and type of transmission additive that you choose.
Note: It is good to check your fluids at the 3,000 miles marl which is where most people get their oil changed. In case the ATF brand that you use is not so pricey, it is better to replace or add more regularly. That is better than ending up spending more on repairing when things go wrong. If you use your car frequently, a regular checkup is quite crucial.
Conventional Vs. Synthetic Transmission Additives
This is a very debatable topic since users prefer different types of transmission additives for their vehicles. In case you are new to this, the differences are:
- Conventional: is ideal for some older car models. There are some car models that have been using conventional transmission additives since the beginning. So it is better to stick to this instead of changing it and experience unwanted issues.
- Synthetic: is resistant to heat, cold, oxidation, sheer, and more. In fact, it is more durable at higher temperatures, so it provides better performance. Synthetic transmission fluids also tend to last longer as well which is why many people prefer using them.
Type Of Transmission Additives
There are 3 different types of transmission additives for vehicles which are:
- Dexron III / Mercon: is one of the most common transmission additives. It works with most Fords, GMs, and imports with great quality and performance.
- HFM-Style: is similar to the previous type, but it provides slightly different friction characteristics. In the market, HFM fluids also go under a few different names as well since imports also use it.
- Type F: It was ideal for Fords with bronze clutches although this type is not common anymore. That is because modern vehicles no longer use bronze clutches since the 1970s.
In case you want to step up the game and go for famous brands of transmission fluids, here they are:
- Castrol: is a global company that provides high quality automotive and industrial lubricants. Their products are top notch, and their business has been going on since 1899.
- Pennzoil: has the base in Houston, Texas which is nearby. This brand has been creating innovative formulations for automative needs since 1913. It is an international oil company, and it is the big producer of motor oil, gear oil, and car transmission fluids.
- Valvolin: has world headquarters in Lexington, Kentucky. This company has a big reach as it has been producing high-quality automotive lubricants and oils since 1866.
Sometimes, the problem may lie in the transmission system of the vehicle for poor performance. In such a case, one needs to repair or change the transmission system. But in most of the cases, the problem lies with the transmission fluid, and the additives are the way out. The properties of the best transmission additives we have listed above vary a lot. Therefore, you should carefully go through the product description and choose the one as per your requirements. They are the best in quality and will revive the original performance of the vehicles.
