Well this is just my opinion but I have always used Dexron 3 until recently when I serviced the box and tried kosher manual multi-grade trans oil but the shift cold is notchier and not as slick hot so needless to say its coming out and Dexron 3 is going back in 
why do we bother 
as I have said before any oil that can withstand the punishment of an auto-trans is good enough for me

+1, but has anyone tried a quality 10w 40 engine oil as I have used it in trucks, and curious about it in car boxes. why do we bother as I have said before any oil that can withstand the punishment of an auto-trans is good enough for me rigga said:
Engine oil is not able to withstand the shear forces that a gear set exerts, its not designed for that application.
I am sure that Allison agree that it is a substitute in their auto boxes and Isuzu use it in their manual boxes, but as I say I have never used it in a car. I use the red stuff in my box also but was just curious, that was all.

Cobblers 
Honda recommended only engine oil in there passenger cars gearboxes from day dot up until the mid nineties they have roller/pin bearings and helical cut gears and are bullet proof 
no oil pumps either or silly troughs or funnels

Not so engine oil was used in all manual Honda passenger vehicles from the early seventies until the mid nineties these had helical gears and roller bearings as do many other gearboxes, however box service interval were every 24k (no harm in that) 
Hi Jamie I actually edited my last post because I did not want Rigga to think I was being nasty

Spose you think you got away that don't you, sin in haste, repent at your leisure. engine oil was used in all manual Honda passenger vehicles from the early seventies until the mid nineties these had helical gears and roller bearings as do many other gearboxes 
Personally I preferred the shoe mender version
That's cool mate. I don't think the use of ATF/ engine oil is really worth arguing over.
That's the beauty of chim owners, between us all we know an awful lot (mostly poo in my case though) and we can share this to improve, modify and repair most things on our cars.
And i'm sure rigga would not have taken offence anyway as you used the word "Cobblers" and not "b
ks".

Yea cobblers to you too .... Personally I preferred the shoe mender version
Edited to show who the cobblers was aimed at

Just to make a constructive (ish) comment for once, does Dexron III have a GL rating like the Diff oils do. I'm sure that is the rating which denotes the speed and torque load qualities of the oil.
Without wishing to get off topic , I use a 75/90 fully synth in my GKN diff, but specifically one with a GL5 rating I'm guessing diff loads would be similar to gearbox loads in which case you would think any oil designated for gearbox use would be rated as such.
