    2002 QUEST, Not driving for 4,5 months, jump started yestoday,
    when at low speed, can strongly feel the gear changing like being knocked
    by someone. When at 50mph or higher, the vehicle starts vibrating.
    Later, the engine service light is on. Is there any relations between
    them? Like to know what is going on here?

    Hi qiebixuefu,

    Yes, vibration and engine service light (ESL) on are related. The ESL comes on not only for engine problems. It also includes all transmission problems.

    Check the level and quality of the transmission fluid. You might need to drain/replace it. Bad fluid will cause transmission shifting issues.

    You should get the codes out at Autozone or Advance and see what they are.

    thank you for your replies, got checked say, the broken

    pressure line solenoid and oxygen sensor,

    had both changed,

     

    but now the problem is , I still can feel the gear change from 1st

    to 2nd, although not as hard as before, indeed, much better,

    but don’t think it’s normal. anyone know what may

    be the problem, or what to inspect? Thank you again!
