Posted 29 September 2010 - 02:19 PM

Here is a list of the lube specifications from Nissan for the WD21, D21, and some caR50. The caR50 Pathfinders use the same transmission, transfer case, and differentials as the WD21, so lube specifications for those will be the same. I do not have the information available for the rest, however. The commonly known TSB for the WD21 manual transmission was fixed at the factory when the R50 was introduced. Nothing fancy, just the basics. Please, feel free to add to the list.

Type:
Engine oil - 5W30 (or whatever works best for your particular application)

Manual transmission oil:
  • Gasoline engine - APL GL-4 SAE 75W90
  • Diesel engine - APL GL-3 SAE 90 or 140
Differential oil:
  • Open differential - APL GL-5 SAE 80W90
  • LSDs differential - Use only LSD gear oil APL GL-5 SAE 80W90 approved for Nissan LSDs
Transfer case oil - APL GL-4 80W90

Automatic transmission fluid - DEXRON or DEXRON II (Dexron III is "suitable")

Chassis:
  • Wheel bearings, muffler bearings, steering knuckles, drives hafts - Multipurpose lithium grease No. 2
  • Steering drag link, sliding shaft yoke - Multipurpose lithium grease No. 0
Power steering fluid - Automatic transmission fluid DEXRON or DEXRON II (Dexron III is "suitable")

Brake fluid - DOT3 or DOT4. DOT 4 has a higher boiling point than DOT 3, and also absorbs much less moisture. Both are compatible with zero issues

Clutch fluid - Brake fluid DOT3 or DOT4. DOT 4 has a higher boiling point than DOT 3, and also absorbs much less moisture. Both are compatible with zero issues

Fill quantity:
Engine oil 4 cylinder:
With filter change
  • 2WD - 4.0 quarts (3.79 liters)
  • 4WD - 4.5 quarts (4.26 liters)
Without filter change:
  • 2WD - 3.5 quarts (3.31 liters)
  • 4WD - 4.0 quarts (4.26 liters)
Engine oil 6 cylinder:
With filter change
  • 2WD - 4.25 quarts (4.02 liters)
  • 4WD - 3.7 quarts (3.5 liters)
Without filter change:
  • 2WD - 3.8 quarts (3.58 liters)
  • 4WD - 3.2 quarts (3.03 liters)
Engine oil 4 cylinder diesel:
With filter change
  • 4WD - 7.9 quarts (7.48 liters)
Without filter change:
  • 4WD - 7.1 quarts (6.72 liters)
Manual transmission fluid - 5.1 quarts (4.83 liters)
REFER TO THIS THREAD FOR THE TSB INFORMATION ON OVER-FILLING THE MANUAL TRANSMISSIONS. http://npora.ipbhost...?showtopic=2621

Differential:
Front
  • R180A - 2.75 pints (1.3 liters)
  • R200A - 3.1 pints (1.47 liters)
Rear
  • H190A - 3.1 pints (1.47 liters)
  • C200 - 2.75 pints (1.3 liters)
  • H223B - 5.85 pints (2.77 liters)
Automatic transmission fluid - 6.15 quarts (5.82 liters)

Steering gear:
  • Manual - .75 pints (.35 liters)
  • Power - 2.15 pints (1.02 liters)
Coolant: (includes coolant recovery tank, if so equipped.) Use regular "green" fluid, it is Ethylene Glycol. Do not, under any circumstances, mix red and green coolant. Destruction of parts will ensue.
  • 6 cylinder - 11.1 quarts (10.5 liters)
  • 4 cylinder gasoline - 9.25 quarts (8.76 liters)
  • 4 cylinder diesel - 13.5 quarts (12.78 liters)

Automatic transmission fluid oxidation in degrees Fahrenheit, life expectancy in miles:
175F - 100,000

Soon, but not yet. I changed manual tranny amount from 1.5 to 5.1...

Lets take the time to put the unit of measurement next to each quantity, just for clarification and the numbers have not been double checked yet. I'll try to get to it later, then we can clean up and pin... ;)

Thanks and good job Pinky!! :aok:

Some really great info here! Could we also add "Litres" to the quantities to help out the Canadians?

Pints are easier for me to measure than quarts... I've got enough old pint glasses around :beer:
but yes, Litres would definitely help us xD

I edited a little, thanks B for changing the MT level. This is just kind of a rough draft, everything was copied word for word out of an updated shop manual covering Pickups and Pathfinders from 1970-1989. Obviously the information is a little old, and Nissan may have updated some of their specifications along the way; such as the TSB for the manual transmissions.

I also haven't checked this information against a Nissan FSM, since I can imagine it would be a little difficult to find one for a diesel Terrano, 2WDs, and the few 4 cylinders out there. :shrug: If someone has access to that specific information, feel free to chime in. :beer:

Hopefully this can be edited to be as close to 100% correct as possible and used as a reference in the future.

My FSM says to use "Dexron" for the transfer case (1991). But I guess it's ok to use the GL-4 stuff. I've heard people saying they use the same thing for the transfer case and the (manual) transmission... I assume this is ok? e.g. Redline MT-90? How about using 75w90 in the front and rear differentials? Seems way easier to find (and shouldn't be too much different) than 80w90? It even has the identical diagram on the "viscosity index" page of my FSM...

The TSB for the transmission says 5.1 L (litres) not quarts, so I think that needs to be updated? We should pin this thread, I keep having to look around for it :) I think the t-case capacity is missing?

Good point, I keep forgetting to double check the quantities/units. I'll pin it and go trough it tonight.

If it's equipped with the same TX-10 as in the WD21 (not the all-mode transfer case) it does.

It can take either or, actually. The manual for my 95 specifies atf for the tcase but the older wd21s specify gear oil.

To add to that, most people run what ever goes in their tranny in case of leaking seals, so an automatic runs ATF and a Manual shift runs gear oil...

did we ever get a quantity for the T-case?
Does it have to be gl-4 for the t-case? I know we use gl-4 instead of gl-5 for the manual trans because of the brass synchros, but the T-case doesn't have synchros, does it?

Also, I know I have the H223B diff because it took 2.7 quarts, but I don't have that sticker indicating an LSD. Are all H223Bs LSDs? Or did Nissan make some H223Bs open? I would think that one of the other rear diffs would be the ones that are open because they would be lighter duty.

And Sewebster asked the same question I have. It never got answered

The T-case calls for 80w-90, but the manual trans calls for 75w-90.
Would 75w-90 be ok for the t-case?

Well, the '94 (and 95) Pathfinder FSM claims Genuine Nissan ATF (which is probably Matic D) or Dexron II for the t-case, so basically use Dexron III. I have no idea if gear oil will work. The '94 FSM says 2.32 quarts. :shrug:

There are H223B open diffs, I have one. 94 FSM says 2.96 quarts, same as my R50 diff.

Well, the '94 (and 95) Pathfinder FSM claims ATF+3 (at least that's what I think "Nissan ATF*3" is) or Dexron II for the t-case, so basically use either ATF+4 (all ATF+4 is synthetic and meets minimum specifications since it's a licensed fluid, and ATF+3 isn't sold/made anymore) or Dexron III. I have no idea if gear oil will work. The '94 FSM says 2.32 quarts. :shrug:

There are H223B open diffs, I have one. 94 FSM says 2.96 quarts, same as my R50 diff.

well now I'm pissed. I thought I was done with ATF I hate that crap. It gets everywhere and I hate the smell.

Found a blurb in the "changing transfer oil" section in the '94 Hardbody FSM that says "When changing transfer oil completely, Genuine Nissan ATF or equivalent type DEXRON II or gear oil (75W-90) may be used. Do not mix Automatic Transmission Fluid and gear oil."

So throw in some M1 75W-90 in that and be happy!
