I've owned these B&M Shift kits before and I was never disappointed in the results. Crisp, clean shifts and a little more get up and go....quickly !

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 wouldn’t fully shift into 4th gear. After a week and a half of me racking my brain to figure out what I screwed up I finally noticed this. I added a picture of where I did it incorrectly and marked the correct spot with green.

I did everything to the T, and now I have massive slip going from 1 to 2. Shifts nice and hard under average or moderate acceleration, but terrible shifting at wide open throttle.

Did the kit for a 2000 s10 2.2. Took about 10 hours from start to finish. Makes the transmission shifts just pop into the next gear, firm shifts. More line pressure for reliability. Very good product.

Good price and a quality shift kit. I have installed several and enjoy the crisp shifts and longevity the kit adds to transmission life. Sold the truck at 96,000 miles still chirping the tires in Strip mode.
