Many transmission failures are due to overheating and fluid contamination. Conventional transmission services remove only a small portion of the contaminated fluid from the system. Any remaining contaminated fluid diminishes the effectiveness of the new fluid and allows deposits to form more quickly, reducing the ability of the fluid to cool properly and leading to further breakdown, overheating and transmission failure. The use of the VPS Transmission Cleaner prior to the fluid exchange gives the new fluid an environment that will not be overloaded with contamination and deposits.
