The orginal ATF for the 3rd gen. auto was Dex IIe, which is slighly ticker than the current Dex III and syn. I only know of Cenpeco making Dex II, which is used in semi trucks, big rigs and hydrolyic systems, because the equip. lastest longer with Dex II than with Dex III. Are there any Maxima enthusists still using Dex II and what other companies still make it.

Also is there a board like this great Maxima board except for Mercedes? -- couldn't find one with Dogpile and Yahoo searches.

 

Dexron II would have been equivalent to Nissanmatic Type C fluid. Nissan now makes Type D (equivalent to Dexron III), and issued a TSB stating that it was to be used an all their auto transmissions. Synthetic is still the best, because it won't thin out at elevated temperatures as any of the conventional ATF's.

 

I'm in the process of rebuilding my auto tranny and was curious if I should install synthetic ATF instead of Dextron. I'll probably install the Nissan OEM fluid that they recommend. I just have to figure out which OEM fluid I going to use Type C or D simce I never knew they had two types.

 

Mobil 1 (and others, I'm sure) are Dextron III compatible and more...

If you plan to rebuild your tranny I thought I'd mention the two TSB's that are for the ve tranny.

One has to do with the tranny no being able to shift when placed in reverse. It has to do with a snap ring on the reverse clutch drum, and if the reverse clutch drum retaining groove shows wear to replace the reverse clutch drum. here are the part numbers
drum assembly-reverse clutch: 31511-80x03
snap ring: 31506-80x12
plate-dished: 31535-80x07

The other service bulletin had to do with the differential pinion shaft being worn. And they say that debrey from a worn differential pinon mate shaft can cause: 1) slipping on acceleration. 2) Hesitation and/or stalling when cold. 3) abnormal noise coming from the trannsmision while driving. To solve the problem they have a countermeasure transmission differential case, which they say will help improve its lubrication
Case complete-differential : 38411-80x01

As for the ATF Nissan does reccomend that an ashless type be used. I'm going to look into if this is something that all ATF manufacturers clam this or not. I'm doing the VB and cooler and have just ordered a case of Royal purple ATF for the project.

 

On the Bimmer.com, they list a transmission filter kit, but does the 93 use one? I thought there only a screen.

Also when does the gear grease go? How offen should it be replaced? Is there a drain and or fill plug for each of the trans axels?

 

the filter screen isnt supposed to be all that important it'll only catch larger stuff. In the vb there is a pilot filter and I was very suprised to see that courtesy doesn't stock it, they will have to order it for me. I think this something worth changing if anyone plans to do the vb mod. cost ~$7

 

What's the vb mod.? and is it hard to do?

 

It goes for about $50
I'll be doing mine next week so I cant say how difficult. But I have the directions and it involves droping the tranny pan, removing about ~15 bolts to lower the valve body, then replacing about 5 spings, drilling a couple holes, enlarging a coulple holes. Not a mod for the inexperienced there is alot to **uck up.
shift kit ~$50,
filters, gaskets, clip, o ring, from courtesy ~65

the shift kit makes first and second grab a bit faster and helps prevent burning up first and second.
there are other things that are included in the kit but they can only be installed if the tranny is out.
