Slushbox Oil

Probably an old chestnut here, but here goes.

Got a Mitsubishi Galant 2.0 Auto Estate.

Handbook says that the 'box should be filled with "DIA QUEEN ATF SP II" Bit of a trundle round the 'net comes up with this being an out of production Chrysler oil, an equivalent as being Dextron III. Wandering down the local motor shop, they don't stock Dextron III, just ATF and Dextron II. Motor shop bod (who's normally pretty on the ball to be fair) reckons that Dextron II will be fine ?

SO ... a) does DIA QUEEN ATF SP II Dextron III ? and b) does Dextron III Dextron II in this case ?

Thanks

I think dexron claims to be compatible with a lot of other specs, did you check out the bottle to see if it's listed ? are you sure it needs changing , is it burnt/ leaking ?

I changed the auto fluid in my accord once and did not notice any difference, and it's bloody expensive stuff . some cars never need atf changing at all these days, not sure about yours though to be honest

What difference do you notice when changing your engine oil or coolant?

If you are not sure, why mention it? If the car has a regular transmission oil change regime then the owner had best stick to it. Certainly Dexron needs to be changed regularly. The 'boxes that are 'sealed for life' are designed specifically for this and use a special expensive fluid. Dexron ATF is cheap by comparison.

No. You may use Dexron III instead of II, but not the other way round - III is to a higher spec.

I didn't realise II was still available. Local Halfords only stocks III.

Rubbish- 1.20 a litre even for valvoline synthetic DIII spec atf.

DII will be fine for the OP, so long as he changes it at 2yr or less intervals.

i'll get m' coat... then ;) It's just that it's not like the engine oil, it does not get dirty at all does it ?

It does, and if it's anything like engine oil it gradually breaks down at the molecular level.

I could be wrong :)

It does get slightly dirty as the paper clutch disc linings wear into it. However this is of little consequence compared to the reducing lubricity as it gets older with work. It is primarily to top up with fresh charge of the additive component that is the reason for changing Dexron and explains why it is not necessary to change all of the oil [not even possible with most automatics]. The superior quality of the oil used in 'sealed for life' auto's is the main reason for having no oil change interval. However it is now recognised that even that superior fluid starts to degrade at around

100,000 miles on average and it is advisable to change 'for life' fluid every 100,000 miles or so if one can be arsed.
