Diff/Gearbox oil change

Going to do a full service on the truck. Know about engine oil. Have a bit of a grey area on transmission. I am thinking GL5 front and rear diffs but cant put this into gearbox so GL4 goes in yes? Also the amounts for each application please.

Thanks in advance

Re: Diff/Gearbox oil change

Hi Bounce
Done exactly this job last weekend so have the info
Front axle SAE 140W API GL-5 (2 1/4 pints req'd). I couldn't get a straight 140W grade but put in SAE 85W/140 grade.
Transmission SAE 75W/85 API GL-4 (8 5/8 pints req'd).
Transfer box DEXRON ATF III automatic transmission fluid API GL-4 (2 quarts).
Rear axle Hypoid LSD oil API GL-5 (2 1/4 pints).

DO NOT USE GL-4 in GL-5 and visa-versa where recommended as this will damage these units
I found the front axle, gearbox and transfer box oils in good condition after 70K miles but the rear LSD oil was VERY black and burnt. This LSD oil should be changed every 36K miles BTW Also do not use any of these so called 'oil modifiers' to change gear oils into LSD oil as they're a load of ***** IMO, get the right oil for the job

From your description GL1-5, this sounds like it is fully synthetic?
If so this will be OK, a bit overkill in a transfer box though, but perfect for a gearbox, the changes will be nice and light even on the coldest mornings.

Re: Diff/Gearbox oil change

Transfer oil type in Nissan acutely depends on the transmission type:
auto - GL4 gear oil
manual - DEXRON III.
But I recommend not changing the type of oil during the life of the transfer so use what coming out if it, in D22 it will be DEXRON III.

Not correct.
Dexron III and API GL-4 are both suitable for D22's, Dexron III if the truck has an easy life, GL-4 if it is a worker e.g. regular off roading or towing, or any of the other criteria as defined as harsh condition in the W/S manual.
I tow a lot therefore use GL-4 @ 75/85 viscosity, it probably started of with Dexron as did all of them.

Recomended transfer case oil changes are:
Regular/normal use 30,000m or 48 months
Harsh use, wading, desert etc or towing 18,000m or 24 months

Re: Diff/Gearbox oil change

I could not find anything in the service manual to back your comments regarding type of transfer oil and transfers are leaving the factory with oil depending on transmission type and I know that from many years servicing Nissan cars.
The deference between oils is just for one reason, for easy identification of oil leak In case of a leak between transfer case and gear case.

If someone wants to change oil type, although I would not recommend it, do a double change so old oil will not remain in the transfer case.

There is only 1 type of transmission in UK D22's, manual, therefore your statement re: different types is irrelevant.
The workshop manual clearly states both types of lubricant can be used, look harder.
Your claim of the only difference being to make it easier to identify a leak, are you having a laugh, I almost fell of my chair, rubbish!
I am certain Nissan never built any of their units expecting them to leak, so why make identification easy?
Lastly although you may, Nissan certainly don't recommend sticking with one oil.
