Greetings all, I need to change the oil in my 95 GQ manual Gearbox and Transfer case. The oil is not dirty but it is old and I suspect is causing my 'sticky changes" in 1st and 2nd when it's cold. It also fills like the transfer case is trying to turn the front drive shaft sometimes (oil to thick/old???) ,clattering sound from that area, dip clutch knock it out of gear and put back and problem goes away. Could the old oil be causing this problem or do I need to look further? ie adjusting transfer case bits. The car has about 270,000k's , has a Lokka in the front and I've changed the hubs from auto to manual thinking that was the problem.
What grade oil do you guys think I should be using in my Box and T.C.?
Thanks Scott, aka Ferret

If your using the recommended weight oil then I would put some Slick 50 oil treatment in the gearbox oil, it worked for me. I suppose it would work in the transfer case but I would asksomebody who knows abot them first.

Synthetics are the way to go- bit dearer but worth every cent- IMHO.
Did that for my GQ some time ago and much smoother especially when cold. Synthetics have MUCH better characteristics than mineral oils. (That's why a lot of high end vehicles specify them as mandatory)
There are many brands available, just ask around. (I forget what brand I used in the end, think it was Mobil but can't remember???? If I do I'll post again. )

Old oil will be thinner and cause less stickyness.. thinner gets around quicker.

If you have just got the car, change every fluid in it... I always do when gettin second hand, then you know how good the oil is... just peace of mind.

Lokka?? Which brand of diff lock? is it a Loka??

Yeah, the 4WD systems one. Got it off a mate. Had the car since March after 9 yrs of Rangie and Disco V8's. Very pleased with it so far. have changed all fluids except the Box and T.C.

Just double check the fluid for your transfer case if your changing it, I've got a 97 GQ and it uses auto tranny fluid in the transfer case. All the series II GQ's use ATf in the transfer cases so double check your owners handbook or manual before you drop gear oil in there.

If you do a lot of towing use 30 weight engine oil in the TRANSFER CASE ONLY . It is a better lubericant than ATF. I used it in both my GQ and GU Patrols with no problems and was recomended to use it by a Nissan dealer.

Hi Ferret,

I've just checked the Forum tonight. Sorry I missed your enquiry earlier.

If you change the oil and clean the strainer, you should refill with the recommended oil and treat with the Bi-tron Metal Treatment which is 100% OIL Based with NO ADDITIVES. The Product is only 30 SAE works because the Oil Product has been reversed engineered and fuses to the metal and will not allow the metals to rub together, under extreme pressure or heat.

Contact me and I will give you further information.

Regards, Brian Rogers. I. D. 525Bi-Tron Fuel & Oil Metal Treatment
