    Performance Made Easy, Two Kits in One!

    B&M Shift Improver Kits are the easiest and most affordable way to gain automatic transmission performance results. B&M's kits modify an automatic transmission's shift timing in order to increase shift firmness and in-turn improve durability. These dual stage performance shift kits are application specific and contain your choice of Heavy Duty or Street/Strip configurations. Shift Improver Kits provide well appointed, crisp shifts delivering unmatched performance.

    Stage 1 - Heavy Duty:
    Firm, positive shifts without loss of passenger comfort for improved performance in all street vehicles. Recommended for normal passenger vehicles and tow vehicles.

    Stage 2 - Street/Strip:
    Provides positive shifts for high performance street use or competitive events. This configuration is for the enthusiast who wants hard, fast shifts.

    Features:
  • Recalibrate your transmission’s shift timing.
  • Select the configuration that best suits your application.
  • Provides well appointed, crisp shifts.
  • Eliminates excessive shift overlap.
  • Less wear and tear on your transmission’s clutches and bands.
