When does it randomly "chug"? while driving , coming to a stop, or idling? How are you retrieving codes {or attempting to retrieve}? A scanner plugged into the OBD lnk under the dash is needed to get codes. 2late4u 1 Quote Link to comment Share on other sites More sharing options...

At 102k miles....what normal engine /trans. services have been done? Sparkplugs Trans oil AND filter change I'm not sure how high a a level scanner system that parts store uses, may need to have it scanned by "shop" {higher level} scanner that can retrieve more than basic codes. 2late4u 1 Quote Link to comment Share on other sites More sharing options...

The two things I asked are the most commonly neglected maint. items that are known common causes of the symptom you describe having and the best place to start. Unfortunately, on a forum responders don't see the state of the vehicle or conditions under which "quirks" are happening to give specific "here's what you need to replace/fix" answers to what little information a poster has given. Particularly when stated SOMETIMES CEL comes on but no codes, with a good scanner that can retrieve code history,more help is made available to fixing a situation. When the CEL is activated, the car's computer WILL log it in it's memory. I suggest you start with these 3 things I posted of and go from there. Keep in touch with us here for more "advice" from the membership here once your NORMAL maint. is up to date. jkeaton 1 Quote Link to comment Share on other sites More sharing options...
2013journey Posted September 12, 2025 Author Report Share Posted September 12, 2025 Actually, it happens at a stop or stop light. Could this be a transmission issue - TCC / solenoid. It has the 12 bolt pan - 6 speed. jkeaton 1 Quote Link to comment Share on other sites More sharing options...

With the complications of todays highly computerized cars, as much specific info of a concern needs to be posted to get good suggestions of possible fixes. Your vehicle is at the point of normal servicing that has been suggested to get done FIRST Next step would be a full system scan, a BASIC OBD11 scanner will not get to certain codes(autozone, O'Rielleys, etc}, as you say sometimes CEL but no codes YES there MAY be something going on with the TCC solenoid, but my experience {having 3 3.6 AWD's} is that this is not a highly likely cause. This is more likely to show up with the 4 cyl. 4 speed trans. jkeaton and Dean H 2 Quote Link to comment Share on other sites More sharing options...
