Squeal from Auto Transmission, changing 2nd to 1st

Hi, bit worried about a noise coming from my 2003, 3 litre auto when manually changing from 2nd back to 1st while decelerating.

I've searched but can't find any posts that seem to describe the same thing.

It's a chattering squeal that sounds like a petrol turbo rapidly spooling down, kind of chi chi chi chi chi in rapid succession. :confused:

I don't regularly pull the auto back to first while decelerating but when I recently had to I heard the noise and it seems to do it every time I repeat the action.

Hoping someone might have some ideas?

Change the fluid and filter and see if any gunk comes out.

Thanks, I'll check that out. Oil and filter are both only about 20,000 old, but it will show up any dramas though.
20,000? I was referring to the oil/fluid and filter in the auto trans.

20,000 it would be due for a change. I try to change mine around every 10,000 - 15,000 depending on how hard it's been driven during that period.

As for my engine oils and filters, I change those every 5000km regardless or how hard it's been driven.
Hi Mavers,

I do engine oil and filter every 5000, I had planned on the Trans at 25,000
