Why customers choose NorthTrail Auto

Smilyeez BG Transmission Service Flush Kit K6600 is a complete two-step cleaning and conditioning system that safely removes deposits and restores ATF performance in step-shift automatic transmissions.

This kit pairs BG PN 106 transmission cleaner with BG PN 310 conditioner (branded as BG Quick Clean and BG ATC Plus chemistries) and includes a compact Smilyeez pocket screwdriver for easy service access. It’s engineered to work with BG transmission service equipment but also provides measurable benefits when used during routine transmission maintenance: cleaning valve bodies and filter screens, stabilizing fluid chemistry, and helping correct shudder or shift issues caused by deposits or oxidized fluid.

How does the cleaner remove buildup without harming components?

The PN 106 cleaner uses targeted detergents and solvents formulated to dissolve varnish, sludge and trapped debris from valve bodies, passages and screens without attacking seals or coatings. It mobilizes deposits so they can be flushed out during service.

  • Breaks down varnish and sludge in hydraulic passages
  • Safe for common transmission seals and gaskets
  • Prepares surfaces for conditioning chemistry
  • Designed for use with BG service equipment for controlled flushing

What benefits does the PN 310 conditioner deliver to refreshed fluid?

The PN 310 conditioner replenishes protective additives and improves the oxidation stability of ATF to prolong fluid life and restore shifting performance. It helps reduce thermal breakdown while reconditioning friction characteristics that affect smooth shifting.

  • Boosts oxidation resistance to extend fluid service intervals
  • Improves friction stability to reduce shudder and harsh shifts
  • Reinforces protective film on gears and clutch surfaces
  • Formulated for modern step-shift automatic transmissions

How is this kit used during a transmission service?

Technicians first circulate or flush the transmission with the PN 106 cleaner to dislodge contaminants, then introduce the PN 310 conditioner to restore additive balance and protect the refreshed fluid. The included Smilyeez pocket screwdriver helps reach drain plugs or access panels during the job.

  • Flush with PN 106 to remove deposits from valve body and screen
  • Install filter and refill while adding PN 310 conditioner
  • Use BG-compatible service equipment for controlled circulation
  • Pocket screwdriver included for convenient access during service

What improvements can drivers expect after service?

After cleaning and conditioning, transmissions commonly show more consistent shift feel, reduced slipping or shudder, and improved response under load. While results vary by vehicle condition and service history, many users notice smoother engagement and extended fluid life.

  • Smoother, more consistent shifting
  • Reduced transmission shudder and hesitation
  • Slower oxidation and longer fluid intervals
  • Preserved performance for both new and used ATF

Who is this for: The Smilyeez BG Transmission Service Flush Kit K6600 is intended for professional technicians and knowledgeable DIYers who perform scheduled or corrective transmission maintenance on step-shift automatic vehicles. It’s especially useful when addressing shifting complaints, preparing a transmission for longer fluid life, or when following BG service procedures using compatible equipment. This kit offers the cleaning and conditioning steps required to help preserve transmission reliability without aggressive treatments, plus a handy pocket screwdriver for routine access during the service.

FAQ

Q: Can I use this kit without BG service equipment?

A: Yes, you can use the cleaner and conditioner during standard drain-and-fill or manual flushes, but BG equipment yields a more controlled circulation for deeper cleaning.

Q: Will the conditioner change my transmission fluid type?

A: No, the PN 310 conditioner supplements and stabilizes existing ATF; it does not replace the specified fluid for your vehicle.
