What are the codes ??? The PCV valve has absolutely nothing to do with the TC. You have a vac leak yea, so maybe it ran better, but I bet one of the codes has to do with the evap system. Like a P 04_ _ something right? Still has nothing to do with with the TC.

 

Yeah, I know I figured that the vacuum leak was causing power loss as well as my vents acting odd. I thought I had the vacuum leak fixed as I replaced a few cracked hoses, but the CEL came back on the next day. The guy didnt tell me the code number when I had them cleared the other day, but I did some reading and found the key trick to retrieve the codes. So far the TC code hasn't come back but a P0455 for a large EVAP leak did, so I need to keep searching for that.
The hardest part about this is that the truck has done this since I bought it in the spring, so I don't know what normal operation is like if that makes any sense. I have driven dodges of this vintage before but I never really paid attention to the tach. I just know it moves around a lot more than my previous Chevy and my wifes Ford Expedition.

 

Well, dhvaughan has a thread about that very code, that I cant find find right now. Maybe he'll chime in, or do a search for threads with his name.
