I'm going to send him a another pcm with a trans settings based off of my wife's tune's trans settings. I've never noticed anything other than perfect shifts in her car (stock trans) and her tune is completely custom tuned with HPtuners. The pcm he has now is all DHP 1.0.
His ABS and TC lights are both on, he says they have been on since he got the car but the cruise worked before. My GM service info says that cruise is disabled when either of the lights are active for more than 2 seconds. I seem to remember my cruise not working when my lights were on because of a bad wheel speed sensor. Can anyone verify?
