Winters Standard to Lockout Shifter Conversion Kit for TH350 & TH400
1490-01
Convert your existing Winters Performance TH350 or TH400 standard shifter into a reverse lockout shifter without replacing the complete shifter assembly. This conversion kit adds a positive reverse lockout mechanism that helps prevent accidentally shifting into Reverse during aggressive driving, racing, or high-vibration off-road use.
The kit also incorporates a neutral safety switch for an additional level of protection. Once properly installed and wired, the switch allows the vehicle to start only when the shifter is in Park.
This is a shifter conversion kit only. It does not replace the transmission-specific linkage between the Winters shifter cable and the TH350 or TH400 transmission.
Includes:
- Reverse Lockout Conversion Components
- Neutral Safety Switch Components
- Hardware Required for Conversion
Linkage Sold Separately: Use the Winters transmission-specific TH350 linkage kit or TH400 linkage kit.

FAQ
What does this conversion kit do?
It converts a compatible Winters standard non-lockout shifter into a reverse lockout shifter. This lets you add the lockout feature without purchasing an entirely new shifter assembly.
Will this work with a Winters TH400 shifter?
Yes. The kit is designed for compatible Winters standard shifters used with GM TH400 automatic transmissions.
Will this work with a Winters TH350 shifter?
Yes. It is also designed for compatible Winters standard shifters used with GM TH350 automatic transmissions.
Why would I want a reverse lockout?
The lockout adds a physical safeguard against accidentally moving the shifter into Reverse. This is especially useful in racing, rock bouncing, and other applications where the shifter is being operated quickly or the vehicle is experiencing significant vibration and movement.
Does the kit include a neutral safety switch?
Yes. The conversion includes neutral safety switch components. Once properly installed and wired, the vehicle can be configured to start only when the shifter is in Park.
Does this kit include the TH350 or TH400 transmission linkage?
No. This kit modifies the shifter assembly itself. The transmission-specific linkage that connects the shifter cable to the TH350 or TH400 is sold separately.
Do I need a different linkage kit for a TH350 and TH400?
Use the linkage kit specified for your transmission and Winters shifter configuration. The linkage controls how the shifter cable connects to and operates the transmission, while this kit handles the reverse lockout conversion at the shifter.
Do I need a new gate plate?
If you are keeping the same transmission and shift pattern, the existing gate plate may remain applicable. If you are also changing the transmission or shift pattern, verify the required gate plate and linkage before completing the conversion.
