I drained the oil from my 93 rodeo gearbox not long after I bought it and replaced it with valvoline 20/50. Immediately 1st gear changes became very stiff when cold. I then put in mobil delvac 1330/30 grade.
This improved it but its still too stiff when cold and not as free as when I purchased the vehicle. I've been advised to try castrol vmx/80. Has any one tried this on the rodeo which recommends the same oil as used in the engine. I would appreciate any other oil recommendations that would rectify the problem.
thanks inadvance for any input.

gday rowdy.
i recently did the patrol gearbox/diff ect
i used valvoline semi synthetic in gearbox/transfer and front diff and full synthetic in rear(lsd).
second gear used to be hard to get in the mornings not now and fifth gear is not winding as much as it used to.
all up cost me about $110 for oil.
and a slab while doing it.—~‘¬‘¥•s’B

Castrol VMX-M works
well on 80 series gearboxes (improves cold shift performance) It was formulated for Mitsubishi (hence the "M") specially for this reason, and it works on Toyotas as
well!
Check the Castrol web site for oil recommendations for all vehicles.
Cheers

G'day Rowdy,
I did much the same as you! I changed the oil in the gearbox of my Rodeo and when cold it was difficult to change into 1st. I put up with it for a month then I changed to Castrol Synthetic (Syntrax, I think, you could
check the Castol web site to see.). It made a definite improvement on the cold mornings.

Rowdy,
I've recently put Royal Purple in my Rangie gearbox, second was tight and the box in general was "talkative". Second is now better bur still no good for a standing quarter, but the box is at a whisper now. Yes this is a synthetic, not sure of your capacity or the price. Gearbox also runs cooler.Keep the shiny side up

Rowdy,
Yes, engine oil is correct but 20w/50 is far to heavy for this particular gearbox from cold which is why the gear changes are stiff. Valvoline make a 5w/30 which is the oil you need to use; Motor Traders are one supplier.

Also what about Mobil 1- ( 5w-50) , ie very good viscosity at low temps, and good range.
As far as I'm aware all Isuzu s use "engine" oil in the gearbox- certainly older ones anyway.
I put Mobil 1 in my sons Gemini gearbox and it works a treat! Gearbox feels better now than when new!
