The B&M Shift Improver Kit can help increase the performance and durability of your stock automatic transmission. By eliminating many restrictive oil flow controls in the transmission’s valve body, it allows the transmission to shift more firmly and reduce slippage and shift overlap, providing crisper shifts and reducing wear. Each kit gives you two modes of performance to select from — RV/heavy duty or street/strip. The heavy duty option provides positive shifts without loss of driver comfort for improved performance, and is designed for regular passenger vehicles. The street/strip option provides positive shifts for high performance street use or for competitive events, and is designed for the enthusiast who wants the hardest, quickest possible shift.

- Two kits in one box — select Stage 1 for RV/heavy duty applications, or Stage 2 for street/strip applications
- Installs easily with hand tools
- Backed by the manufacturer with a 1 year limited warranty
Works great Great product, I installed this while I was doing a total rebuild on my 2002 z71 trans. I added corevette servos, upgraded boost valve, and a few other upgraded pieces. All together it shifts great! I used the HD/Towing part of the kit, and love it. Be careful when installing the aluminum plug in the separator plate, I did it in the wrong port the first time then when I installed my trans back in the truck it wouldnât fully shift into 4th gear. After a week and a half of me racking my brain to…
Great upgrade Great upgrade for the 4l60e. Do the corvette servo too. I also bought new shift solenoids because I was already into the valve body anyway. Everything is working great
I prefer the Transgo kit but I always buy both … I prefer the Transgo kit but I always buy both because the B&M has a few things the other doesn’t include. I always buy both to get everything I want.
