    I'm having some issues with ruff start stops and an intermittent rattle while driving and even sometimes while in park. Always while ICE is running or starting and stopping. It's been going on a while and getting worse over the last 20k miles. It comes and goes and sometimes it's not noticeable but other times it really makes me worried. No codes and engine is running very well otherwise, 45mpg burns a small amount of oil every 5k but not too much and I'm at 200k. Anyway I'm starting to think it could be the transmission input damper. I'm trying to confirm this with an inspection and wondering if I can split the trans and engine just enough to get an endoscope to the damper. So my question is can this be done with the trans and engine in the car and if so what will need to be removed first to get them apart. If anyone has done this inspection before, please give me a rundown. Cheers.

    Damage to any part of the damper disc leads to its further destruction. Therefore, it is unlikely that your damper problem could suddenly stop reminding you of itself.

    See this topic.

    You may have other engine and transmission problems that need to be diagnosed carefully. Problems do not always come out in the form of codes. Pending codes can sleep for a long time while the engine is already in a stage requiring intervention.
