The pcm will shift out of manual 1st to 2nd at the WOT setting specified in the tables. You can start in 2nd, but if stomp on it it will kick into 1st. The easiest way to solve this is to use a shift kit. http://www.summitracing.com/parts/tr...-hd2/overview/ It is exactly what I want. The last kit I did I set the shift firmness to towing so it didn't snap hard. It was fine in 2 hi, but 4 lo was was harsh at higher rpms. I might leave the firmness stock and have the firmness adjusted in the pcm. I do think hooking up the 4 lo wire will help with shifting in drive, but that's it. For now, I will hook the 4 lo wire up and deal with it. I just changed the fluid and flushed it out with Dex 6, so I'm thinking this winter I'll do something. That was like $100 in trans fluid...
