Smilyeez Transmission Flush Kit K6600 — Cleaner & Conditioner with Pocket Screwdriver, Restores Smooth Shifting

Smilyeez BG Transmission Service Flush Kit K6600 is a complete, professional-grade set that cleans automatic transmission components and replenishes fluid performance with a cleaner, conditioner, and a pocket screwdriver.

This kit brings together BG-formulated cleaners and conditioners engineered for modern automatic transmissions. Built for service bays and skilled DIYers, the K6600 combo removes deposits from valve bodies and filter screens, stabilizes fluid against oxidation and heat, and helps restore smooth shifting. The included pocket screwdriver offers a small but practical tool for on-the-vehicle access and quick adjustments during service.

How does this kit clean and prepare a transmission?

The BG cleaner in this kit targets built-up varnish, sludge, and deposits inside valve bodies, screens, and passages without damaging seals or internals. It loosens contaminants so they can be flushed out during a service, restoring proper fluid flow and valve function.

• Rapidly dissolves deposits from valve body and filter screen
• Safe for automatic transmission internal components and seals
• Prepares the system for fresh conditioner and fluid replenishment

What performance benefits will I notice after using the cleaner and conditioner?

After treatment, transmissions commonly regain firmer, more consistent shift feel and reduced hesitation. The conditioner boosts the fluid’s resistance to thermal breakdown and oxidation, helping maintain performance under heavy use.

• Reduces transmission shudder and hesitant shifting
• Improves oxidation stability for longer fluid life
• Helps preserve original performance characteristics of ATF

Is this kit compatible with modern step-shift automatic transmissions?

Yes — the BG chemistry in the kit is formulated for the high-temperature, high-shear environment of modern automatics. It is intended to be used with BG transmission service equipment for optimal results, but can be part of professional or informed DIY maintenance routines.

• Designed for step-shift and other modern automatic transmissions
• Works best when paired with BG service equipment for flushing
• Safe for use in systems specified by BG product guidelines

What’s included and what small tasks can the pocket screwdriver help with?

The kit supplies BG transmission cleaner (PN 106) and conditioner (PN 310) in quantities suited for a transmission service, plus a compact Smilyeez pocket screwdriver. The tool is handy for removing access panels, loosening clamps, or adjusting brackets encountered during a service.

• BG cleaner PN 106 to remove deposits and varnish

Who is this for: This kit is aimed at service technicians, independent shops, and knowledgeable vehicle owners who perform transmission maintenance and want BG-grade chemistry in one package. It suits anyone seeking to recover shifting quality and prolong ATF life in step-shift automatic transmissions, provided they follow manufacturer and BG service-equipment instructions for safe, effective flushing and fluid replacement.
