Please Please STAY AWAY from B&M They are worthless!!!, I put one in my truck an '03 Silverado 1500, 4.8 4l60-e tranny, and now I am rebuilding my tranny. I ordered the kit from a very reputable place in stl, and they even called B&M (Break and spend your Money) They sent us a kit, and we installed it.
1. They first said we did it wrong. *Right me and my buddy about 20+ year building highperformance vehicles.
2. They said oh well check the holes. *True, they sent us the wrong gasket!!
3. Then I raised hell and found out talking to about 20 people at B&M and finally getting to an engineer that oh that kit won't work in your truck, it is for 97-2001, not like the kit advertised 97-and up!!!!

B&M is good for one thing pointing fingers and pissing you off.

Go to www.4l60-e.com and order the transgo, I just got mine in the mail with my K19 Master Kick butt kit, and the seperator plate is all i ordered since the kit includes everything else you would ever want, the instructions just with the seperator plate ROCK!!!

Good luck and feel free to call me with questions
