As the title of this thread suggests, I just had a new tranny installed at 38k miles. (part # 32010 CD008)

I got the car back yesterday, and everything seemed ok. Once it was warmed up though, I started noticing this nasty noise in first gear. I'm sure we're all familiar with the typical clutch noise, the sound of rocks rolling around when it's idling. Well this is a much louder, much more exaggerated sound, though similar. It only seems to happen between 2k-4k when accelerating in first gear...

Also, there seems to be a HUGE loss in power across the entire RPM range.

The service writer of course ccouldnt hear the noise, and claims the car pulls fine. But the bottom line is, I know my car, and its slower and noisier than before the tranny swap.

Any ideas how to proceed? Or what the problem may be?

 

Bumping out of desperation.

Surely someone has heard of something similar? Or has a vague idea what could cause such a problem?

 

mabey you should let it break in?

 

I kicked around the idea, but per the dealership, there is no break-in period. Of course, they are quite often incorrect...

Even if that is the cause for heavy power loss (which I highly doubt), that still doesnt explain the wretched noise in first gear.

 

My tranny was swapped at 37k, seems ok so far. I don't think the trans swap would affect the power unless the clutch is slipping or something.

 

Update:

Met with the tech that installed the tranny. He claims not to hear the noise either. Yet when I drove into the parking garage at work this morning, co-workers asked if they swapped the engine for a diesel while they were replacing the tranny. It sounds like a F'in diesel MAC truck driving down the road.

 

Hello? which tranny?
