Replacing gearbox and transfer case fluids
Ok went and bought all the fluids, jacked up the car and removed the bash plates for access to everything.

I cannot get the nut off the gearbox. How much force do you use before breaking it?

Any other tips/advice please?

If you are sure it is the correct nut :D , these are things I do to stubborn nuts:
  • spray with a penetrating fluid, eg Q20, and repeat every day.
  • put reasonably pressure on the nut (with a ring spanner) and then hit the nut with a hammer (and copper driver?), while applying the pressure. The shock load often loosens the nut. You will probably need someone to help you with this.
  • heat it with a small LPG torch. beware of wires, hoses etc.
I hate stubborn nuts! :evil:

Hi Guys,
Just a small tip , use a Metrinch socket if possible as they are not prone to stripping as I found most ring flats does tend to strip nuts as the annular gap
between ring and nut is bigger . I found this especially on Gedore flats.

Does anyone have a picture of where the nut is situated on both gearbox & transfer case? If you manage to loosen them, how do you refill them and how do you know if the level is correct?

This is the transmission for a Gen2 Manual

Fill at the filler plug until it starts running out at that plug. Car needs to be level.

Re: Replacing gearbox and transfer case fluids
When I shift between 1st and 2nd and between 2nd and 3rdn the change pretty stiff... or put it this way, very unrefined, rather than stiff. I was wondering if a change of fluids will help this?

I experienced an amazing improvement in shift quality/refinement when I changed the oil in my Patrol's gearbox. I used Castrol BOT 130 M synthetic and it was like fitting a new 'box: the slight grating going into reverse or between 3rd and 4th simply vanished.

My Gen2 transmission (on a gen3 Di-D) had the standard 1st - 2nd 'hesiation' shift when I first fitted it.
I changed to Caltex EasyShift and the 'hesitation' is gone.
A good oil therefore seems to do it.

Re: Replacing gearbox and transfer case fluids
OK I think I'm going to have a bash at changing the fluids, perhaps next weekend. Do I just ask for Caltex Easyshift? Is there another option?

Any gotcha's I need to know about or advice as to how best to go about it?
