Hi all
I just got this vehicle with 137k and no service history so took to a trans shop. They serviced the trans, said it was pretty clean etc and used Valvoline Dexron VI to refill. I'll likely be doing 3.5T towing soon.
I found the datasheet for Valvoline Dexron VI and it doesn't state meets any other specs. Datasheet attached.
From what I can tell the trans needs:
G 055 540 A2, which may be the same as (from research on forums) JWS 3324, which may be the same as ATF0WS.
So, I have found a few fluids that meet G 055 540 A2, some without the A2, does that matter or is there no non A2?
Datasheets for Castrol and Shell products attached.
Maxlife meets G 055 540 A2 but # against Dexron VI and WS, implying these are lower viscosity fluids than Maxlife.
Interestingly two different datasheets I found for Maxlife also attached do not say G 055 540 A2, and some state JWS3324 as # I.e. not recommended.
So what to believe?
Some of those meet other JWS specs (3309 not 3324, implying 3324 is a higher spec), and none seem to state ATF0WS. I note many state Toyota WS, which may be the same but generally lacks thr associated 4 digit code. Can anyone clarify all this?
I wonder if the person stating G 055 540 A2 is JWS3324 is wrong and instead JWS3309 is equivalent?
The multi vehicle fluids that do appear to meet G 055 540 A2 also appear to meet Dexron VI. That gives me some confidence, but not total.
So aside from the questions above about what oil numbers are actually the same, should I demand they drain and refil with a G 055 540 A2 fluid?
Annoying when you decide not to DIY and this happens. Guy at shop says they use that in the aisin 6 and 8 speeds and no issues known.
I am not saying he is wrong, but seems like any risk is on me unless they swap the fluid or agree any issues in next 30k or so are on them (which I bet they won't agree to).
I'm after well informed views here please, that's why I came here. Not just "go use factory fluid" stuff.
Is the Valvoline Dexron VI almost certainly fine for this trans, or not?
And hopefully tech gurus can clarify why some of the brands say G 055 540 A vs A2, and how JWS3324 compares to it etc.
I do note the viscosity of Valvoline Dexron VI looks fine.
But there must be more to oil makeup than just viscosity stuff that is on the datasheets...
Thanks!
