What's a good shift kit for a 01 DURAMAX

Has any one heard of transco or transgo something like that?

Transgo is an excelent shift kit company. They have been at it for some time and everything that I have been around of theres has been very good. I have not spent much time on newer trucks, but on older trucks w/ th350, th400, 700r4 and early 4l60e transmission they work great. See http://www.transgo.com/

I am getting one put in my 01 DURAMAX I will let you know what I think!!! Thanks

I found out today that it is a transgo stage 3 shift kit!
