Many car owners change oils and filters or overhaul the entire gearbox, but the primary problem lies in the "gearbox pot" (torque converter). The truth that many don't tell you: The most important part inside the gearbox pot is the (friction ring) Energy Woven + Category: HTS - Search Number / L-113 Series. It is the beating heart that transfers power from the engine to the gearbox. Unfortunately, most people use cheap "commercial" (paper) friction rings that burn up in our climate's heat. The result? The shudder returns after a short period. Wear of the ring produces deadly "iron filings" that enter the gearbox's brain and destroy it completely. We don't just open and close the pot; we "develop" its performance: We know the difference between types: There are many types of friction rings on the market, and we have chosen the best and highest quality globally for you (the upgraded, high-endurance type). Advanced carbon material: We install a friction ring that withstands high temperatures and prevents direct friction (iron on iron) to ensure no filings are produced in the future. Agency performance and better: Strong grip of the pot, smooth gear changes,
