Convert your existing Winters Performance standard shifter into a reverse lockout shifter designed specifically for TH350 and TH400 automatic transmission applications.

The Winters TH350 & TH400 Reverse Lockout Conversion Kit upgrades compatible non-lockout Winters shifters with a positive reverse lockout mechanism that helps prevent accidental reverse engagement during aggressive driving, competition use, or high-vibration off-road conditions.

This conversion kit allows builders to upgrade an existing Winters shifter without purchasing an entirely new assembly. The integrated neutral safety switch provides an additional safeguard by allowing vehicle startup only when the shifter is in the Park position.
