Synthetic G'box oils

Castrol VMX-m is voted the best oil for a cruiser 5 speed gearbox (as most know they suffer from bad shifting) it is either part or full synthetic-not sure as i put ATF in mine(auto).

I use Lubrimaxx Transgear (fully synthetic) in gearbox of GU TD42.

I have Castrol Syntrans in my Jack Gbox and transfer case. Is a bit over $10 per litre (in a 20L drum).
Fully synthetic. Changed mine from conventional oils at about 40k - had a whine in 5th (most Jacks post 99 do). Mine whine has virtually gone now - very quiet indeed. Synth may have helped or it just ran in.
Considering the intervals involved, will probably stick with it.Gotta have red sand on those boots !

Yep yep yep, my vote is for Redline too.
Kept the gearbox on my 200sx together even though I was drag racing it regularly, and was putting out over 200kw at the wheels. Far beyond it's design brief.
In turbo racing circles Redline is considered the best, however I'm not sure how that translates to 4WD.

David,

I cant speak for 4wd experience as I dont run it in my 4wd but I can tell you
that I run Synthetic (castrol) in my wifes Commodore and have had no
drama's. She has done 170k and has not had any problems with the transmission. The box in her commodore are known for trouble around 120k. So I can only assume that the synthetic is doing a good job.

Cheers

gday david.

it soon shut up 5th gear in the patrol and early morning shifts heaps easier.got over no fraser.
get on with life(more weekend fun)

I use Royal Purple in the transfer case, gearbox and diffs, for me it made a difference, I made the purchase based on life cycle costs and not the initial cost which is high, no hiding that. I've put Royal Purple in my Rangie 5 speed and it's made a lot of difference, the choice was to buy some 300 watt speakers or 7 litres of Royal Purple, the Royal Purple won, since I've had it in 2nd gear has decided to rejoin the rest of the gearbox and now works, it was extremly hard to get when cold, Ok when hot.
The only problem I would say I have is when working the box on my GQ really hard I get a hypoidy type of smell inside the cab, this has something to do with my placement of the vent in the engine bay, I just haven't moved it as yet. Hope this helps, there is a local supplier in Siderney if you are looking local. I know it isn't Australian made apologies for that. Again as usual my opinion only, hope it helps. Keep the shiny side up

Have used Castrol VMX 80 in may last two troopys first had done 320k on original box with no problems when sold, current car has done 113k again no isuues.

I use Redline MT90 in my GQ 4.2 diesel gearbox because it is one of the best oils money can buy. Quality of shift is great whether hot or cold. Expensive at around $10 per litre.
