I have this noise coming from the driver's side wheel/tranny area
whenever i hit a bump or whenever the car shifts from 1st to 2nd i hear it.
its like a rattling noise, its VERY annoying. this is currently the only unsolved issue on my car. once i take care of it, i will be happy

here is the vid
you can hear it when the car shifts at 3,000 RPM

Possibly the upper strut mount?

 

^upper strut mount is checked and fine

but i did make a discovery yesterday.
i had my front end jacked up and on jack stands, both wheels off. i was changing the sway bar end links. when i was on the driver's side, i jacked up the control arm, tightened the end link, and released the jack. when the control arm went down, i saw my tranny move around and make the same exact rattling i've been having. so i jacked up the control arm again and released the jack quickly, and sure enough the tranny was moving around a little and making that rattling noise.
i had my tranny replace with a new/used one with 60k on it back in july (july 10th IIRC). should i go to the person that swapped my transmission? or is this an easy/inexpensive fix?

 

This is probably too obvious but did you check the tranmission mounts, paticularly the left side? Unless the problem existed immediately after you got the car back from the shop, they are probably not at fault. It maybe as simple as the guy who put the tranny back in did not tighten everthing appropriately after getting everthing lined up.

 

I had the same thing going on up until yesterday. I changed all of my engine mounts along with the transmission mount. Tightened up my axle nuts and the sound is gone.

 

new vids posted.

so should i change my motor and transmission mounts?
