Noise when auto trans. shifts

[bocody]

I've noticed a noise lately when my 03 Vibe shifts from 2nd to 3rd and 3rd to 4th gears. It sounds like a piece of light metal vibrating when it shifts and it only lasts a second or two. It hasn't affected performance at all. Anyone else noticed this?

What year and mileage? You may want to get the tranny flushed and filled. A member here had his tranny go a few weeks ago and he had 64k miles.

It's an 03 with 31K miles on it. It sounds like a piece of tin vibrating.

Could be a heatshield or something...... and when you hit 2nd or 3rd gear the engine is hitting higher RPM and thus more vibration. try revving it slowly in park and see if it happens.

Thanks I'll try that. That was my first thought too, some kind of a shield.

I've tightened everything I can find although I haven't been underneath the car yet.

It sounds like a piece of tin vibrating.i have the same prob........does not do it all the time.....but it is a pain in the (removed)..on mine it is from the back somewhere...around muffler it sounds like...it has done it since i bought the car almost 2 yrs ago.i now have 97,000 kms on her.....so it could be something loose.

I talked to a co-worker tonight and he said it sounded like a cam problem to him. If I have 3 or 4 people in the car and I'm accelerating up a hill the noise is louder. It appears any increase in load on the engine makes it worse.

Well, the engine will knock when going up hill like it says in the manual, don't know if that's what you're hearing. But what's weird for me, is when I open and shut my back doors I can hear something vibrate underneath in the back, but not always. It sounds like it's outside the car so I don't think it is tools around the spare but it's kinda weird. Lately shifting has been **** in the city...... a bit jerky, I know it's a small transmission and they kind of do this but I drained the tranny twice already and put in Lucas Oil Tranny Fix as well. I may just get the thing flushed, but ya...... there are a lot of squeeks and vibrations in this car.
