B&M 70360 Shift Improver Kit for Automatic Transmissions

The media could not be loaded.  wow. just beautiful. in the vid im 3/4 throttle. regular driving its not super hard like the vid i posted. its perfectly clean and crisp shifts. at that 3/4 throttle, it knows your on a mission and is there to help.... it'll actually bark 3rd if itime everything right. will bark second everytime if you just nail it and go to pound town. this is in a 2003 gmc yukon 4x4 running the street strip option. I put the same kit with the rv option in the same year suburban and I noticed almost nothing. just a tad bit cleaner and more firm 1-2 shift, thats about it.With my yukon in the vid, nothing eles is done to the truck except an airraid cold air intake. bone stock otherwise. I flushed the fluid twice and used mobile 1 dexeron vI synthetic fluid with this kit. 1,467 miles on the kit so far. not a single issue or even the slightest blip of an error. very nice.

Nothing bad to say, factory sealed, all parts and pieces included, better price than what we can get local - which helps profit margins :D

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.

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 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.

I hear Transgo is much better by everyone and more detailed installation instructions

👍🏻👍🏻👍🏻👍🏻👍🏻

Lo use en una Silverado 2005 4l60e, todo queda perfecto!

Cambios bruscos y firmes, funcionó bien en mi Silverado 2003 TH 4l60e
