Just had my 2004R rebuilt by Russ Merritt. My previous build with another vender included all the billet parts but it just wasn't right. It would slide into the next gear from the very first day. I got it back from Russ looking like it was just built by GM. The attention to detail is incredible. The exterior looks new. Installed it over the weekend and it works better than any tranny that has ever been in my GN. Shifts are crisp at low throttle and firm at full throttle. It works perfectly! No leaks, no issues, none! Russ is a fanatic when it comes to details. I have seen some of his work on friends turbo Regals and I am so very impressed to say the least.
