Outer Limits 4x4 Board

Need Advise.

Did a Gear box oil change on my GU patrol a few months ago.
Bought a standard type 90 grade gear oil.
the gear shifts when cold are very tight, only happened with the new oil.
have i used the wrong oil ?
What oil is recommended ?

Cheers Grant

for the manual should be using, SAE75W-90 API GL4 3.8Litres.
had the same problem in a 01 challenger used 80W90 gear shift became shit house put the 75W-90 all good. i think i used castrol stuff from bursons.

i use penrite 80w-90 hypoid gear oil works good, although when i changed the gearbox oil yesterday i bought 85w-140 hypoid instead by mistake, i put that in anyway and hasnt made any difference for me

i just had my clutch done, and we put 90w penrite oil in, and i have noticed the last few days that until its right up to temp that the gear changes are extremly tight, i might have to go and ask for some 75-90 hehehehehe gota love the freebies!

recently had nissan do 120000 km service. they changed all oils and now gear changes are tight when cold aswell. down shifting almost impossible without doubling the clutch. intested to find out if common problem or are nissan using the wrong gear oil???

slightly off the topic but if anyone need work done on gu/gq patrols send me a private msg..been in the trade 8 years had some experience with gq and i own a gu..specialize in bmws

Changed my gear oil tonight!
used Castrol 75-90.
Shifts like a dream!
thanks for the replies and advise, i rechecked the old bottle of gear oil i used before and found a had actually put in a 85-140 hypoid (what a Numb nut!) any wonder it was a bastard to shift!

thanks agian. Grant
