After switching to this fluid, gear changes feel much smoother. It really improved the overall driving experience.
Works perfectly in my manual car and reduced the rough feel when shifting. Feels more precise and consistent.
Shifts are smooth even during cold starts. The fluid feels slightly thicker at first, but performance is excellent once warmed up.
Noticed better engagement between gears and less resistance. It’s been very reliable over time.
You can tell this is a premium product. Keeps everything running smoothly without any grinding.
Helps protect the transmission and reduces wear. Pouring is a bit slower due to the viscosity, but overall very effective.
