I can build the trans the same as art carr. The fact is he did all the r&d so he has the parts. There are other companys that make parts for them that aren't so well known. Manual valve bodys eliminate the need for the cable. I have a 700r4 manual in my monte ss that works very good. I removed the 2004r to take advantage of the 308 first gear ratio. 305's have no torque so it really helped me. We all know there is a proper way to abuse a transmission. That said, I think the 2004r would be great if built properly. I've seen gn's launch on the back bumper with 10 inch slicks using the so called weak 2004r.
