5 best additives in manual transmission

The additive consists of organometallics, which "heals" cracks and enlarged gaps in the mechanical box. Reviews show that the positive effect on noise reduction is noticeable after 30 minutes of driving. The tool increases slip between rubbing parts, which increases rolling and protects against scoring. The additive reduces the temperature of the transmission fluid, so the gears do not shift hard even after a long drive. Drivers note the elimination of howling, vibration and hum. For the price, this is the most profitable option, since one bottle is designed for 4-6 liters of ATF. But it is inconvenient to fill the agent in the manual transmission - it is better to dilute it in a canister and apply it when changing the oil.

The estimated use of the additive is 1 bottle per 1-2 liters of gear oil. Drivers usually pour 2-3 bottles into the manual transmission.Nanoparticles are distributed over the box and fill worn areas in bearings, synchronizers, gears. There is no chemical reaction with the transmission fluid, since the restoring particles have a polymer shell. At the same time, the fluid properties of the lubricant increase, it is quickly distributed throughout the manual transmission in the cold season. The total service life of the ATF is increased up to 5 times.

The additive is available in a 100 ml bottle and has a thick sediment. Before use, the product must be well mixed and poured into a heated manual transmission. One tube is enough at a time. The liquid metal agent reshapes the splines on the gears, so shifting is smoother and crisper. Another tool retains oil on itself, which better protects friction pairs from wear. Customer reviews indicate a reduction in noise in the included gears, but some still have a rumble in neutral. The additive promotes better coasting.

The additive is available in a 9 ml tube and is fed into the control or filler hole of the mechanical box. For most passenger cars, 2 syringes are enough. The manufacturer claims that due to cermet, manual transmission parts completely restore their shape. This happens on the move, but for a complete revitalization, you will need to drive 50 hours or 1500 km. The agent does not enter into a chemical reaction with mineral and synthetic oils. Reviews show that after applying the backstage moves with two fingers, and the vibration in the cabin becomes noticeably lower. The official website shows the results of revitalization tests on metal with complete elimination of wear.

The additive is best for heavy wear mechanics because molybdenum disulphide restores worn parts. Due to this, the teeth are connected more tightly, the bearings rotate more quietly. All car owners in the reviews confirm the reduction in noise on boxes with a range of 200 thousand km. The manufacturer recommends using the product when changing gear oil, adding one tube for every liter of ATF. Therefore, for most manual transmissions, you will need 3-4 tubes. The pleasure is not cheap, but the box heats up less on long trips, the gears turn on more easily, despite the linear temperature expansion of the metal. It is convenient to feed the product into the manual transmission due to the narrow spout. This allows you to fill it through the breather or control hole.
