Engine transfer noise in cabin

My car began having a noise in the cabin that corisponds to the rpm of the engine. At first it was very light but over 100 miles it became louder. It sounds like a speedo cable rubbing within its housing as an example. The guy at the dealership had the car for 3 weeks and could not find the source. He suspects noise transfer through the frame but doesn't know how. Does anyone have an idea. Thanks. MYMACH5

Check This

Look at the back of the motor, just below the intake manifold. The shift cables run through the valley below that area. There should be a foam pad under the shift cables where they lay on the back of the block. If this foam pad is missing or out of place, you could get a noise transmitted into the cabin via the shift cables and/or shifter.

Check the belly pan bolts to make sure they are tight. Look especially at the larger T-30 TORX screws on the outide edge of the mid-pan. There are 3 per side of these T30's. I hope this is it because it is an easy fix.

Thanks for the reply guys.
Problem solved. Based on the ideas you gave me I looked and found that the throttle cable was rubbing the serpentine belt. I can't believe the mechanic didn't see that! The belt cut at least 25% into the cable. I can't wait to see the mechanics face when I show him. He wanted to replace the transmission!

Unbelieveable.:frown How bad is the belt???

This illustrates perfectly why a little while back I stated: If Shadowman had a shop up here in my area, other reasons for selling would have been 86'd, and the GT would still be in my garage.

The belt appears to have no damage.

Come on Pockets, you never drove it, so it never needs repairs, but if it did, Shadowman would be one of the best.

The second photo shows how the cable was looped under a bracket by Sawgrass Ford when they put in a new transmission.

The third photo shows the cable rubbing the belt.

The forth photo shows how the cable should be free of the bracket.

The fifth photo shows the cable free from the belt.
