I sent my valve body and governor to Extreme Automatics. They set it all up and sent it back. I love how it works now, around $325 all said and done. This was on a low mile stock olds 88 2004r, now in my 68 with 4.11 gears and 275/60 rear tires. Definitely worth the money, no trial and error. I have buddy who did the governor weights and springs in his Monster 2004r that had the same low shift points and he had the pan off 5 or 6 until he liked it. Extreme was well worth it.
