If I just replace 4 litre of ATF, what is your recommended interval for
next ATF change (4 litre again)?

Bro...Is yours still under warranty ?

I Yes,... just follow your owner's manual, to avoid the risk of "Void Of

If No,... change for next 40,000 km as most of transmission expert
recommend. But this is not conservative, may be less than that with the
following precautions (occur before 40,000 km):

1. Watch for leaks or stains under the car

If there is a persistent red oil leak that you are sure is coming from
your car, you should have check to see if it is coming from your
transmission or possibly from your power steering system (most power
steering systems also use transmission fluid and leaks can appear on the
ground in roughly the same areas as transmission leaks - FWD). If all
you see is a few drops on the ground, you may be able to postpone repairs
as long as you check your fluid level often. If transmission fluid levels
go down below minimum levels serious transmission damage can occur.

2. Check fluid for color and odor

Most manufacturers require that you check transmission fluid levels when
the vehicle is running and on level ground. Pull the transmission
dipstick out and check the fluid for color and odor. Transmission fluid
is a transparent red oil that looks something like cherry cough syrup.
If the fluid is cloudy or muddy, or it has a burned odor, you should
change your ATF.

3. Be sensitive to new noises, vibrations and shift behavior

A modern transmission should shift smoothly and quietly under light
acceleration. Heavier acceleration should produce firmer shifts at
higher speeds. If shift points are erratic or you hear noises when
shifting, you should have it checked out immediately. Whining noises
coming from the floorboard are also a cause for concern. If caught
early, many problems can be resolved without costly transmission

BTW, what ATF brand you use ? ...just want to know...he...he...

Yeh cheuman what brand did you use? S40 equip with controlled slip torque
converter clutch,if you use lousy Dinosour oil(mineral) dexronIII,it
won`t last for maybe 20000km. Dexron is more for older type of cluctch
which is ON and OFF type not for nowadays modern controlled slip type.

I search on the net and found this esso specially made for AW
transmission that Volvo use:-

Thanks mates for your warm and keen responds.

I have my S40 service at FA, so I bet they use the original ATF for Volvo.
Anyway, the warranty has just expired.

Did you ask to FA guys ? ... why "no need to change ATF for life" ? as
you mentioned earlier in this topic.

Why they changed your ATF ? Because of the expired warranty ? ...Hemmmmm..

BTW ... competition is more and more tough ... transmission model with
slip-controlled lock-up the clutch ...... then ATF lock-up the
transmission ... then transmission lock-up the customer ... "no need to
change the ATF for life, BUT change your "ATF Drain Plug every 30,000
miles" ... What does it mean ? (you might read carefully your owner
manual) .... ho...ho...ho...bloody marketing gimmick.

BMW 745i use modern transmission "slip controlled and lock-up clutch" ...
ZF 5-Speed transmission, and the recommended ATF (According to the test)
is still DEXRON-III and MERCON specification.

SAAB and VOLVO share the auto-transmission for their latest models, use
AW (aisin Warner) complexe electronic controlled transmission ... slip-
controlled and lock-up clutch...... So who is the majority owner of AW
transmission ?.... It is a Japanese .... TOYOTA ... President AW Europe
is Susumu Kasai from Jepun ... he...he...he...

Toyota also lock-up the ATF for their LEXUS model using Toyota T-IV ATF
(with same gimmick ... "No Need To Change the ATF for Life" ... he.he.he
still burned and must flush the ATF) ... this ATF can be packed with SAAB
or VOLVO ori ATF ... just packaging matter....yeah ... competition on the
globalization world ... WIN or BANKRUPT ...just using Complex Electronic
and LOCK-UP Technology gimmick.

Yes,it is good to frequently change the atf,just make sure that you fill
back the correct grade of atf that your car is using. If you go to bawah
pokok workshop,the BPWS mechanic is not that educated to diffeentiate atf
grade,they will just said RED color ATF OIL.
Nowadays there are so many type or grade of atf,just becareful the grade
you use.

Just my 2 kupang!

I remember paying RM40/liter for original Volvo ATF 8 months ago.

The Volvo specialist advice me not to gamble by trying alternative brand.
He said if anything goes wrong with your transmission, it will cost you
RM3K – RM 4K to repair. Can you take the risk?”.
So I use original Volvo ATF.

BTW, one will have the feel good feeling once the ATF has been changed
regardless of any brand. It is only after sometime that we will know if
there is any ‘side-effect’.
