Does anyone know what this broken part is. It fell off my car after the tranny downshifted into second on moderate acceleration.

Looks like a heat sheild - made of aliminum and it has PN 1616708 on it.

The driveline now has a bad vibration and it's there in neutral as well - shifts OK though and fluid seems alright.

Before this happened I noticed some vibration today at around 2500.

I won't be able to get the car up on stands for while hence the question about this thing.

 

looks like an engine cooling fan blade replace it at once !!!

 

Got it in one.

I just went down and checked - there's a blade missing.

I had my tranny rebuilt a couple of months ago. The converter was bad and it vibrated a lot eventually taking out the tranny because they all tried to tell me it was anything but a bad converter.

It was really difficult to get the shop to redo the work because they say they don't make enough on these things - so when this happened I thought here we go again because the vibratation was pretty much the same as before.

Anyway thanks for your response.

I 'm relieved to know that I don't need another tranny.
