Lubegard Kooler Kleen Transmission Cooler Flush is a concentrated, water-free detergent solution designed to remove grease, sludge, and metal debris from transmission coolers and lines before installing new or rebuilt transmissions.

Before fitting a replacement or rebuilt transmission, contaminants trapped in the cooler and cooler lines can quickly damage fresh fluid and internal components. Lubegard Kooler Kleen is formulated to dissolve and carry away friction materials, metal shavings, and deposits without introducing water or harsh chlorinated solvents. It’s suitable for a wide range of transmissions, including automatic, continuously variable (CVT), dual-clutch (DCT), and manual gearboxes.

How does Kooler Kleen protect a new or rebuilt transmission?

Flushing cooling circuits prevents abrasive particles and residue from circulating into new transmission components. Kooler Kleen lifts and suspends particulate contaminants so they can be drained away, reducing the risk of premature wear in a freshly installed unit.

  • Solvent system formulated to dissolve grease, sludge, and friction material
  • Removes metal shavings and other debris from cooler and lines
  • Avoids leaving residues that could contaminate fresh transmission fluid

Which transmission types can I use this on?

This product is engineered for compatibility across common transmission designs, making it useful for mixed-fleet shops or DIYers working on multiple vehicle types. It safely flushes cooling passages for automatic, CVT, DCT, and manual systems when used according to the instructions.

  • Suitable for automatic transmissions and torque-converter circuits
  • Works with CVT and DCT cooling loops where fluid cleanliness is critical
  • Also appropriate for manual transmission cooler lines when applicable

Will Kooler Kleen harm seals or pollute new fluid?

The formula avoids water-based detergents and contains no CFCs or chlorinated solvents, reducing the risk of seal swelling or corrosive residues. After flushing, the system can be drained so newly added transmission fluid remains uncontaminated.

  • Non-chlorinated chemistry to minimize solvent-related risks
  • Rinses contaminants without leaving harmful residues behind
  • Designed so fresh transmission fluid is not polluted post-flush

How is Kooler Kleen applied for effective flushing?

Application is straightforward when following vehicle-specific service procedures: introduce the product into the cooler circuit, operate the transmission or pump as required to circulate, then drain and install new fluid. Proper flushing technique ensures the cleaner reaches hoses, coolers, and internal channels.

  • Introduce cleaner into cooler inlet or follow OEM flushing instructions
  • Cycle the system to circulate the detergent through lines and cooler
  • Drain flushed material fully before adding specified new transmission fluid

Who is this for: Lubegard Kooler Kleen is intended for professional technicians, service shops, and experienced DIY mechanics who install replacement or rebuilt transmissions and need a reliable, non-water-based cleaner to remove contaminants from cooler assemblies and lines. It’s a practical choice when ensuring that new transmission fluid and components start life free from abrasive debris and deposits.
