Generic TH350 Turbo 350 Kickdown Cable Delete Plug — 6061 Aluminum CNC-Machined Seal

Compact, machined 6061 aluminum plug that seals a Turbo 350 (TH350) kickdown cable port for clean, leak-free transmission builds.

When modifying or simplifying a TH350 transmission where the factory kickdown cable is removed, you need a reliable way to close the cable port without compromising the transmission housing or fluid integrity. This kickdown cable delete plug is engineered to be a direct-fit, durable substitute that preserves a tidy under-hood appearance while providing a secure seal in custom and restored drivetrains.

How does this plug seal the kickdown port and prevent leaks?

The plug is CNC-machined with tight tolerances to match the kickdown port geometry, producing a consistent, pressure-resistant surface against the transmission bore. Its precise fit minimizes fluid seepage paths and reduces the need for additional gasketing in most installations.

• Machined from solid 6061 aluminum for dimensional stability
• Tight tolerance fit designed for TH350/Turbo 350 kickdown port
• Surface finish that mates cleanly to the transmission bore
• Reduces risk of fluid leaks when installed correctly

Will this adapter fit my Turbo 350 (TH350) transmission without modification?

Yes — this piece is designed as a direct replacement for the factory kickdown cable mounting point on TH350 transmissions. Typical installations are plug-and-play for transmissions that retain the original port dimensions, though confirmation of port type is recommended prior to purchase.

• Direct-fit for common TH350 kickdown ports
• No welding or drilling required for standard applications
• Works with stock and many aftermarket transmission housings
• Check port shape and diameter before ordering for rare variants

How durable is the 6061 aluminum construction under heat and road conditions?

6061 aluminum provides an excellent strength-to-weight ratio and resists corrosion in typical engine-bay environments. While not a plated or stainless material, 6061 holds up well to heat cycling and vibration when installed properly, making it suitable for performance and street applications.

• 6061 alloy resists corrosion and mechanical wear
• Retains dimensional stability under normal engine heat cycles
• Lightweight compared with steel while maintaining robustness
• Recommended for typical automotive operating conditions

How simple is installation and what tools are required?

Installation is straightforward and intended for DIY mechanics and professional shops alike. In most cases you’ll need only common hand tools to remove the old cable assembly and press or thread the plug into place; some installations may benefit from a sealing compound or light torque to secure the fit.

• Basic hand tools typically sufficient: wrenches, sockets, picks
• May require light torque or a press fit depending on the port
• Sealing compound optional for added leak protection
• Can be installed during transmission service or swap projects

Who is this for: This kickdown cable delete plug is aimed at transmission builders, restorers, hot-rod and swap enthusiasts, and anyone removing the TH350 kickdown cable for custom throttle or shift control setups. If you’re streamlining wiring/cabling under the hood, performing a transmission swap, or sealing a redundant port while keeping a professional finish, this machined 6061 adapter gives a long-lasting, neat solution that fits the Turbo 350 platform.
