When our '02s water pump began to fail, there was a whine for about 2 minutes after a cold start. Never was able to identify the source. The WP did not leak out of its weep hole.

Finally, about 1500 miles later, the engine started to run hot so we we replaced the pump. Noise gone.

Of course, if the drive belt you removed also drives the WP, that should have eliminated the noise... :whistle: 馃槆

There is an old thread revived recently this week among this topic. Talks about an emissions vacuum line and some whine noise. Something about a suction line back to the fuel tank.

At the top of the engine is also the PVC located on the back side. Got to thumb around to find the hose to the air intake plenum. If it's clogged enough, there may be a whine. It's behind the PS reservoir and around the left.

Welcome aboard,
Did you check ATF level (per Chrysler instructions, Idling after shifting all gears, level ground)? (@Jeppman, posted about quick and dirty check for level at the 'crook' of dipstick when off and cold)
What RPM is the engine idling at when warmed up? (if over 650-700, could be vacuum leak)

i would've said that earlier but you said the sound comes from the top of the engine

if it doesn't shift out of 2nd it's in limp mode

what check engine codes do you currently have?

Sounds like the transmission is in "Limp Home" mode, giving you only mechanical 2nd gear and reverse.

You can try the "key dance" procedure to pull OBD codes (but it only pulls "generic" codes) - if you can pull the trans codes that might point you in the right direction.
In any case, check the input and output speed sensors, ATX relay, and solenoid connector - with any luck it could be a simple fix.
