WnSEu TH350 Transmission Shifter for GM Turbo 350 — 12" Chrome Direct-Mount Gated Lock-Out

WnSEu's TH350 12" transmission shifter is a replacement chrome stick designed to mount directly to GM Turbo 350 automatic transmissions and includes a gated lock-out safety feature.

This complete 12-inch shifter assembly is made for classic Chevy and GM vehicles that use the Turbo 350 (TH350) automatic transmission. It replaces the floor-mounted or console shifters with a direct-transmission mount, delivering a polished chrome look and a mechanical gated lock-out to help prevent accidental gear shifts. The unit is sold as the shifter only; cutting the vehicle floorboard is typically required for installation and professional fitting is recommended.

What makes this TH350 shifter compatible with my Turbo 350 transmission?

The WnSEu shifter is engineered to bolt directly onto GM Turbo 350 transmissions without modifying the transmission housing. It uses the TH350 mounting pattern and linkage geometry so it lines up with factory-style shift levers.

• Direct-fit for Turbo 350 bolt pattern
• Designed for standard TH350 shift linkage connection
• Chrome-plated 12" shifter arm sized for common floorboard locations
• Works with most classic GM rear-wheel-drive configurations

How does the gated lock-out improve safety and usability?

The integrated gated lock-out provides a positive detent pattern that separates Park/Reverse/Neutral/Drive and prevents accidental shifts into gear. It gives clear mechanical feedback so drivers can feel each position and helps reduce inadvertent gear engagement during driving or parking.

• Mechanical gate prevents accidental gear selection
• Distinct detents for consistent tactile feedback
• Durable internal components for long-term reliability
• Chrome finish for easy cleaning and corrosion resistance

Will installation require cutting the floorboard or extra components?

This shifter mounts directly to the transmission, so in many vehicles the stock floor or tunnel must be modified to accommodate the shifter arm and base. The product does not include installation instructions and professional installation is advised.

• Mounts directly to transmission—floor modification often necessary
• No installation hardware or step-by-step guide included
• Professional installation recommended to ensure proper alignment
• May require custom linkage or console work depending on vehicle

What finish, dimensions, and parts are included with the shifter?

The assembly features a 12-inch chrome-plated shifter arm and a complete gated shift mechanism. It’s supplied as a complete stick assembly meant to replace floor-mounted shifters on TH350-equipped vehicles.

• 12" chrome shifter arm for classic styling
• Complete gated shift mechanism included in the assembly
• Designed for use with Turbo 350 transmissions only
• Sold as the shifter assembly—additional trim/console pieces not included

Who this is for: Enthusiasts restoring or upgrading classic GM cars, trucks, and hot rods with a Turbo 350 transmission who want a direct-mount, chrome 12" shifter with a gated lock-out.
