Today I tried to shift my truck manually to almost red line because it felt like it had been holding back under acceleration. I have a smoke problem at idle and she idles fairly rough. Well I could not get it past 3100-3200 rpm far short of the yellow line and when I backed off the throttle lots of black, I am wondering if this may have something to do with my tranny signals or the IP calveing? Any suggestions? I did post a while back and mentioned that at times when the tranny is cold it feels like it is slipping or I am doing a brake stand NO movement but only when I went from reverse to forward and cranked the wheel hard one way or the other, probably unrelated. Got me stumped. Do I need the codes read or some diagnostic done?
