Every so often, my 2008 Chrysler Town and Country feels like it holds back: the speed stays the same, but the RPMs go up. It makes a funny sound.

It will stop for a couple of days, but then, it happens again.

It has no diagnostic trouble codes (DTCs) for the transmission or engine. It has a big oil leak at the top of the engine.

  1. What could be causing this?
  2. How do I diagnose this?

  • Did "he" see the van while it was having this issue?

  • No because it only does it once in a while Nov 4, 2016 at 20:08

I would definitely address the oil leak first and foremost, but it sounds like your transmission is slipping.

    Intermittent problems are frustrating because they never happen while the mechanic is looking at the car. Try to find a pattern for when it happens. When did it start exactly?

  • I am just driving and it happens what speed I am going itbstays on thatbrpm go up then it goes away Nov 4, 2016 at 21:05
  • Does it happen soon after you start the car? After you've been driving for a while? Uphills? Downhills? Cold morning? Warm afternoon?
