  1. The 2500 and 3500 series trucks are not known for condenser problems as they do not use the same one as light duty 1500 series.Make sure you weren't sold a bullshit story.
  2. After you bought it, now your going to check on any issues with the 8 speed???? That transmission is an absolute piece of ****** and has been since it was released in 2014. You can't fix the unfixable.
  3. Thats the engine oil cooler line, the trans cooler lines are the smaller ones.
  4. You need a better scan tool, that code is the passenger presence system. There should be a symptom bite after the initial code.More information is needed to help you.
  5. Very common, debris fell into blower motor cage,You can try blowing compressed air into blower cage, if that doesn't work the blower motor will have to be removed and the cage will have to be cleaned. We see this all the time with do-it yourselfers and jiffy lube places changing the cabin filters without making sure that stuff doesn't fall inside when they pull the filters out.
  6. Check the motor mounts, left one breaking is very common and will clunk on acceleration.
  7. That is the intake manifold.Why do you want to replace the plugs? They are supposed to need replacement at just about 100,000 miles.
  8. That is not a job for the beginner or someone who is just mechanically inclined. I just had to do a left valve cover and lifters and camshafts on one 2 weeks ago. The cowl and wiper transmission and the tray it sits in all has to be removed to gain access to the intake manifold bolts.That truck is absolutely miserable to work on. Wait till you try and replace the starter. We are a GMC- Buick dealer and we all hate them when they come in.
  9. There is no way they missed THAT when it was checked in. That happened on their lot and they are bull shitting you.
  10. The torque converter shudder is with the M5U 8L90E, 8 speed transmission, not the 6l80E. You don't do a transmission fluid exchange with the new HP fluid on the 6 speed. It uses DEX 6.The torque converter probably came apart sending metal debris threw the whole unit, ruining the pump and causing low line pressure in turn burning up the clutches and causing the shuddering your feeling.The converter alone would be a waste of time and money. That needs to come out and overhauled.

    Mr

    I would replace the intake gaskets and while your in there replace both knock sensors and the wiring harness.
