B&M Shift Improver Kit for GM Transmissions

The B&M Shift Improver Kit is an automatic transmission shift kit for GM transmissions. It is designed to firm up shifts and improve shift response. Installing a shift kit (also called a shift improver or valve body kit) helps the transmission change gears more quickly and positively. This reduces the slippage that wears clutches and generates heat.

Key Features:

• Engineered to improve shift feel and responsiveness in GM automatic transmissions
• Helps raise line pressure and speed up clutch apply for firmer, more positive shifts
• Suited to street performance, towing, and racing use
• Reduces clutch slippage, which helps limit heat and wear
• Backed by B&M, a long-time name in automatic transmission performance and shifters
• Multiple kit variations are offered to match different GM transmission models

Choose the specific kit that matches your transmission model. Installation typically involves removing the valve body or pan and replacing valves, springs, and related components. Follow the instructions included with the kit.
