Let me ask you a few questions...
1. Is the sound coming from the shifter, or from under the Hood
2. Is it kind of a squeaking sound?
If the sound is coming from under the Hood
, then your shift linkage may need a squirt of lithium grease on it. To do that, pop the Hood
, and have someone in the car keep shifting until you can pinpoint the part of the linkage to spray. I did that to my car because it would squeak whenever I shifted into second. Been perfect for about 10k miles now.
If the sound is coming from the shifter, then pop the lower console and shift boot off, and try spraying some grease down there too.
