I have a 2003 Lancer ES, it has 86k miles on it all driven by me.
Last week I noticed a buzzing sound coming from the engine area when shifting from P to R or from N to D or R. It’s like a buzzing, it only lasts a few seconds and happens even when car is off (engine off and key in on position) sound goes away after a few seconds without me doing anything. Here is me doing it twice back to back from P to R - https://www.youtube.com/watch?v=ngE7yY4XSbk.
I also noticed that when after driving when I put it in park the engine will rev to about 2 to 2.5k rpm and go back down immediately (and doesn’t do it again). From my research it seems to be a transmission solenoid? There is no check engine light and when I took it to AAMCO they tried to read stuff with a computer but it was clear. They recommended I drive on it until CEL comes on, is this good advise? What about revving when parked is that the behavior of sticking solenoid? I took it to another AAMCO and they recommended I change it. Both places quoted me $360 for labor plus the part.
My questions are, should I change it? If so should I do all of the solenoids or just the failing one? Should I drive till CEL? Do symptoms sound like solenoid? It does it from P to R and from N to D are those the same solenoid?
When I’m driving normally the car feels fine shifts seem good and every gear works.
I did the following at 65k miles:
- Changed Power Steering fluid
- Transmission Flush
- Spark plugs
- Ingition wires
- Cam positioning sensor (both of them)
- Alternator belt
- Power steering belt
- Timing Belt
- Ignition wires
- Spark coils
