X2......I run a Broader Performace C-6 in my truck and love it. Talked to some of the local rebuilders when I was needing a transmission and they all gave a big frown when I told them I was mudracing. Found Jay and gave him a call, told him my intended use, what kind of racing I was doing, and the build of my engine, THEN he told me my options and what I needed. Ordered it soon thereafter. Transmission shifts great, no problems at all and has held up great!!! Jay even worked to find the best shipper with the lowest price. A-1 all the way!
