Chevy Aveo 2011 - 4 speed - noise in D/R when cold

[Brit01]

Hi all,

I have the 1.6 hatchback aveo(2011/12) with the 4-speed tranny.(Aisin).

Lost the manual but I do believe it takes the T-IV ATF. I changed it with the filter at 70,000 kms with Toyota T-IV.

Now at 100,000 kms after a few years of heavy use, daily frequent slow, stop-start traffic etc.

When it is cold and I put it into D or R straight away after starting it makes a slight grinding-like noise. I put it back into N or P straight away.

If I leave it idling for just 1 minute or so and put it into R/D then it's quiet.
Seems to be taking a bit of time to circulate the ATF??

Could the filter be slightly blocked, hence the delay in getting the ATF moving or a worn pump?

Worth performing another filter and ATF change?

What is the general service interval for this tranny?

No other issues - changes smoothly. Level good when cold and hot. I read that these Aisin trannys are robust so would surprise me if anything mechanical is wrong with just 100,000 KMS.


Thanks a lot

just let it warm up a bit unless you want to open up a can of worms, dropping the pan to see what’s up won’t hurt.

Thanks, yes we're doing that now, wife instructed to also. Just 30 secs or so seems to do the job. Don't dare to put it into R before that now.

We're planning to buy a new car this year anyway so don't want to do anymore work on it, just forked out a fortune on a GM AC compressor, timing belt/pump/tensioner etc. Beginning to turn into a money pit.
Had a damper shoot through the trunk's floor the other month after hitting a pothole!!

My wife is getting paranoid now with any noise she hears that something else is breaking on this GM car.

Think I might buy a new filter and gasket, drop the sump and inspect/change the filter
