Default b&m shift kit

What are your opinions on the b&m shift kit? Good or bad buy?

Not good. You basically drill out 3 holes and disable accumulation. You can make a kit like this.
The end result is banging shifts, firm shifts are what you want at most. And the kit does nothing to solve problems the trans might develop over time.

Installation instructions-->>http://www.bmracing.com/bmracing/ins...9500582-03.pdf
Imagine paying $85 for $5 VB gaskets, two drill bits, and spacers that can do the job of a stack of 3/8" nuts.

I installed one of these kits in my 90 TBI truck with a 700r4 about 12 years ago. As the above post stated all I remember doing was drilling out a couple of holes in the separator plate, moving some check ***** around, and blocking the accumulators. It cluncked at part throttle shifts, and the end result was the servo blowing out the side of my trans and leaking fluid all over the road.

Sounds like this is the shift kit in my car, only had it for almost 3 months, one of the selling points was a built 4L60E at 100k, bought it at ~126k and its now at 130k. 1-2 shifts hard if I let it go around 2200-2400, 2-3-4 are all quick and smooth. If I let it shift below 2000 on 1-2 its really smooth and quick, and above about 3500 it chirps the back tires every time, I like it . Its not that bad, I've gotten used to it as it is my DD. It most likely is due to the fact the tranny was rebuilt along with this kit. I'm no pro, very, very, very far from it, but I've heard both the good and bad sides of our transmission and self installation without building the rest of the transmission may turn yours into what happened to Kevin01Z28's truck.

I think most people that have these cars want firm/quick shifts. When I installed the b&m kit in my truck i completely blocked the accumulators, no springs at all. It had the option to install a spacer in the accumulators to stiffen the spring or block it completely. But hell i was only 16 and wanted to chirp the tires hitting second gear without paying for a built tranny, which it did until it blew a couple months later...

just the b&m.....they have a history of having you overdrill feed holes. Depending on which transmission and which accumulator you are blocking it may be ok, but others not so much.
