Has anybody ever installed a B&M shift improver kit? Is it hard to install? I have a C-6 tranny, Iordered a street/strip kit are they a big improvement from stock?

 

I used that shift kit for about three days. I was leaving rubber in both shifts for about 10 feet and it wouldn't shift until it hit about 4 grand. I had it removed by the same tranny guy who installed it. He said he hated them and recommended a transgo. The transgo worked very well. Nice firm shifts without the other problems. Barked second and chirped third but only at wide open throttle. It was behind a 360 in poor condition. I am moving this thread to the tranny forum as it would get more replies that way and that is where it belongs.

 

So no matter if you were going 20 mph it would still leave a ten foot patch of rubber, when it shifts?(Barely even on the gas?)

 

The B&M kit shifts hard at any RPM. It won't spin the tires at low RPM, it will just shift unnecessarily hard. The Transgo kit is throttle-sensitive. At light throttle, it shifts with close to stock firmness. With heavier throttle, the shifts are firmer & crisper. The Transgo kit is definitely better for a street-driven truck. It gives you the added performance under hard acceleration without the harshness at lower RPMs.

 

It took quite a bit of throttle to get to 4 grand just to get it to shift. I didn't know a tranny could shift that hard until I had the kit put in. Of course it didn't leave that much at part throttle but it was quite rediculous. I could still shift from 1st to second manually at any speed just like any C6 will.

 

I just recieved my B&M shift improvement kit. What do you think about the rv/towing improver vs. the street strip one? The kit lets you choose which one you want. The rv one should be way better as far as shifting at a lower rpm shoiuldn't it? My 268h cam cam today also I will be putting that in pretty soon. I'm pretty exited
