It does in one manual - but the other one only mentions SPIII. But then again the manual that says DII also shows the front suspension with coil springs!!  That's what happens when you spend £5 for a manual off eBay! |

| Dexron II is mentioned because its a get you home or to a dealer only measure and the box shouldn't be run on it. |

Dexron is not the correct ATF

Warning on the use of incorrect transmission fluids.
Many people are using the incorrect specification in auto transmission systems requiring Dia Queen SP III transmission fluids, this is due to confusion arising from the fact that many people believe DEXRON III is suitable, IT IS NOT SUITABLE FOT MITSUBISHI AUTOMATIC TRANSMISSIONS requiring SP III.
This confusion arises as Dexron III is a generic specification and not a vehicle specific specification, Dia Queen SP III is far superior in specification to Dexron, so meets these specifications, Dexron specifications, being much lower, do not meet Dia Queen specifications.
Technically most Dexron III specification oils suffer from several problems, the main one's being a differing coefficient of friction, lower tensile and shear strengths, and a much lower rating for operational temperatures.
So what does this mean in real terms?
Differing coefficients of friction means oils meeting Dexron III are not as slippery as that required my Mitsubishi, in real terms it affects every aspect of the transmission from moving around the hydraulic circuits to lubricating the gears themselves.
Tensile or shear strengths means it cannot lubricate effectively when under hydraulic pressure or when between meshing components, basically it is not strong enough and will break down when under normal working stresses in a Mitsubishi automatic gearbox.
Automatic gearboxes work at higher temperatures than a normal manual gearbox, Mitsubishi's work at higher than normal temperatures and require a lubricant rated considerably higher than that of Dexron III without degredation and while still lubricating the gearbox at higher tensile loadings.
Putting in ordinary Dexron III will trash your automatic gearbox.
How did this situation arise?
Many lubricant suppliers cross reference manufacturers specifications, they see a Mitsubishi specifications list it as meeting Dexron III and list their Dexron III products as compatible for Mitsubishi, even though it does not meet Mitsubishi specifications, basically they use generic specifications for cross reference purposes. This means their literature and specification sheets used by retailers is incorrect and the wrong oil is sold to a consumer, although it is not the fault of the retailer as they work from the manufacturer information data sheets.
To date i have cross referenced many manufacturers ATF specifications, and i have only found two manufacturers whose products meet and exceed Mitsubishi Dia Queen SP III as used in later automatic transmissions, these are:
Fuchs Titan 4400 - Fuchs manufacture a range of Titan products for automatic transmissions, the only one suitable is the 4400, nothing else. Many suppliers are passing Titan 3000 off as suitable as it is Dexron III rated transmissions, but it is not suitable for later specification models.
Amsoil Synthetic Universal Automatic Transmission Fluid - This again meets and exceeds the requirements of Dia Queen SP III, and is suitable for these transmissions.
Having checked the specifications of numerous large lubricant suppliers and manufacturers, i have found they all meet Dexron III standards, but not Dia Queen SP III standards; they all fall short somewhere in their specifications and durability.
What will it do to my transmission?
Any lubricant not meeting and exceeding the Dia Queen III specification cannot be used, it will break down rather quickly and turn brown then black as the clutches begin to slip, this burns the oil and turns it black, meanwhile the tensile strength and temperature quickly degrades the oil also. Ultimately it will damage your transmission, and it will be a new or reconditioned gearbox; this depends upon vehicle use and its working conditions as to how quickly it deteriorates.
At the present time it leaves only Mitsubishi main dealers, automatic transmission specialists, Fuchs Titan 4400 and Amsoil synthetic universal ATF as those i can find which are suitable replacement alternatives. |

I would - it's just not worth the risk.
We know that SPIII is recommended - but Dexron has a question mark against it as some manuals say it's OK and others say it is not. |

I put the Titan 3000 in mine so will let you all know in 2 years time if it fails...
However I have a nasty habit of changing cars every year so I guess I might not find out.
I almost never do off road & only tow a light trailer once a month, So its not going to be much of a test.
I do about 50k per year
Car has done almost 200k
The ATF that came out was very dark, So the Titan 3000 is going to be a lot better than that.
Probably never been changed.
There was very little material on the magnets & the filter was clean.
I don't notice any difference at all in the gear changing. |

Resurrecting an old thread, but I was looking for suppliers of DIA QUEEN ATF SPIII and Opie Oils came up (not unsurprisingly). However, they list "Mitsubishi spec oils which meet or exceed Mitsubishi Diamond SPIII", which I assume is not quite the same thing?
The options they list under this heading are;
- Motul MULTI ATF Fully Synthetic Car Automatic Gearbox Oil (ATF)
- Gulf MV ATF (MERCON V) automatic transmission fluid
- Fuchs TITAN ATF 4400 Automatic Transmission Fluid for Japanese cars (confirmed as suitable by Assassin)
- Gulf Multi Vehicle automatic transmission fluid
- Castrol ATF Multivehicle Automatic Car Gearbox Oil
- Valvoline MaxLife ATF Automatic Transmission Fluid
- Millers Oils Millermatic ATF CVT
- Motul ATF VI Fully Synthetic Car Automatic Gearbox Oil (ATF)
- Castrol Transmax Z Automatic Transmission Fluid
Also listed is Amsoil Synthetic Automatic Transmission Fluid ATF but is shown as discontinued.
Given that most of these have fairly generic names, I'm inclined to think that a lot of them may not be suitable but I have no expertise in this area. I would welcome confirmation from someone who knows what they're talking about. |

I thought Diaqueen was only available from Mitsy dealers.
At least one in your list is unsuitable - the Millers Oils Millermatic ATF CVT as it is for CVT transmissions
Many of us use Millermatic SPIII WS or Fuchs Titan. - both available from Opie. |

The Fuchs 4400 is the second-cheapest on there (important when you need 9.7 litres!), and I've been using Fuchs engine oil in Wifey's car for years so I'm inclined to go with that unless there's a significant improvement with the Millermatic SPIII WS.
My post was really because Opie are "experts", so it would be easy to get sucked in and end up buying something that's potentially unsuitable. I'd be quite happy to get on the 'phone to them and get them to revise their recommendations if I had a definitive list. |

I have been using the Millermatic SPIII WS for nearly six years and will continue to do so.
There is a listing for 2x5L HERE for £56. |

1 year update.
The Titan 3000 is still going strong after 1 year gear change still smooth |

Just changed mine used this 20L MANNOL ATF SP III 3 AUTOMATIC TRANSMISSION FLUID OIL 20 LITRE OEM QUALITY
I read through peoples posts and it seems that 3.5 lt is the norm to drain from the box ,
i used a 1.75 pt jug and took 7 full jugs out which should be just under 7 lt have put 6 lts back in , i know it will need more as i have fitted an extra 9 row cooler for towing reasons plus i dont use the one in the rad , the box was not over filled before dropping the old oil which was well past its best bit like every thing else that should be changed dont think the previous owners did much of the oil was dark no burnt smell but very old the engine oil was well used and very black air filter look like it was from a coal mine still putting it all right now |

I have got myself 15L of Motul ATF VI and I'm still unsure whether this newer low viscosity fluid is okay for my gearbox.
Any advice? |
