Review on 🚗 B&M 70239 Shift Improver Kit: Enhance Your Automatic Transmission Performance by Matthew Allen

I used this shift kit with a Stage 2 rebuild and Corvette servo. I have a rebuilt 89 C1500 350 HO and my transmission blew up a few months after the engine was built. I bought a rebuild kit and this shift kit to improve shift times so I wouldn't burn the clutch between shifts, that did it and then some. This kit shifts insanely fast and tight. It shifts into 2nd so hard that the rear end squeaks at 15 mph. I am 110% satisfied with how he brought my truck to life.
