I get a lot of customers wondering about the correct fluids and the capacity that is required. I know there have been tons of post on the site about this, but Im going to put one here with all the correct information from Mitsubishi. I will add more to this as I go along here.

Why is the Coolant fluid part # the same as the Brake Fluid Part #....

Also...could you share when is the "BEST TIME" to actually replace these fluids?

Thanks

 

I suppose I did goof that up. They are one digit apart...simple mistake I suppose. *fixed* Thanks for the good call though...that could have been a mess. "Well I put that so-called brake fluid in the system and well...my brakes no worky now".

I shall see if I cant round up some maint. scheduling and put that up to. I plan on completely updating this post with a lot of factory information that should help people out.

 

awesome thread. That info is honestly really hard to find, even with the search button. And since you have part #'s on there, that makes it that much better!!!

 

Why are the 5sp and 6sp gear oil listed as the same part number?

 

Because you can use the Diaqueen M/T fluid in both. Basically -- it is the same.

 

i thought it was different than the 5spd. isnt that why most people put the MR DiaQueen since its different than the 5spd trannys?

 

This is straight out of Mitsubishi's technical manual. The diaqueen 75w85 works in the 5 & 6 speed transmission's.

 

This is confusing... so if I ordered part #: MZ313376 Will i get regular diaqueen for the 5 spd, or the SUPER diaqueen for the 6 speed? They are 2 different fluids

 

Yes there are 2. One is LSD and one is for the manual transmission.

 

Russell--

I know this is in the manual....but since the manual is stashed away...when you have a chance could you post recommended replacement schedules?

Thanks for your work on this

 

This is something I had already promised doing and I havent really had the time. For what ever reason my computer will not let me get into Mitsubishi. I have to go to another terminal and do it. I am the only person in the dealership who has photoshop and I need that to pull the images to post for you guys. I think its in an Acrobat file though...its is like 437 pages long though. If it is small enough to go on my 4G Flash drive I will save it and see if I can get that thing posted for you guys to use.

I apologize for the wait.

 

they should sticky this.

 

I thought it went like this
5 speed 7585 diaqueen
6 speed Diaqueen 7585 SUPER MULTI
rear & case diaqueen LSD..
There are 3 different lubricants, and just because we CAN use either in the 6 speed does not mean it will work as well.
