Hi guys. I know that these gearboxes are not as common as the others in a Torana, however I'm sure there are plenty out there, and. A fair few would have them in other cars.
So, my question is, what oil do you use?
The standard oil is actually Automatic Transmission Fluid. I know there is oils out there that make it a smoother nicer shift, I just dont know which one.

Anyone with experience in this would be greatly appreciated.

Thanks in advance

I use Royal Purple SynchroMax in my Jerico gearbox and I see that some recommend it for T56's too..

Doesn't the T56 have friction lined synchros like the T5? If so then ATF is required for these, they're basically the same material as clutch linings in an auto.

Personally if GM recommends ATF then I would stick with that, the trans is built for it rather than gear oil. If you do go with something else, it needs to be a product that is recommended for 'boxes that normally use ATF, not a standard gear oil.

I just use ATF in mine, and did as well in the '00 Camaro SS I had around for a while... (same box as in the Torana).  Either normal ATF or GM synchromesh seem to be a safe bet to go with.

Thanks guys. I have Dextron3 in it now but was hoping for a better feel. I have read in the past that Transmax gives a smoother shift and a quieter box.
Might just leave it as is.

Thanks again guys

Had major issues with hard shifting with my Monaro, sometimes could not get 3rd gear. Put Nulon fully synthetic trans fluid in and a bottle of thier additive (tall white botlle) and now its a new transmission, better than its ever been. One of my friends was having similar issues with his truck and put the additive in and fixed his issues as well. $20 for the additive, best money spent.

So do you need to use the nylon oil, oil can I just use the additive?

Make that Nulon oil

I did both, not much dearer than Castrol or any of the other brands, my friend with the truck only used the additive and it worked great.

There is no drain plug so removing the current oil will be a pain. The exta from the additive wouldn't be enough to cause an issue would it? As in, extra amount of fluid

I wouldn't add the additive to ATF, it will be designed to work with their oil

Ok so maybe I found an alen key head , that looks like a plug in the right side of the extension housing. I haven't tried yet, but MAYBE if I remove this plug looking bolt the oil will drain out.
MAYBE!!!

Still can't find a " drain plug" ;)

Ok, so Nulon fully synthetic and the additive.
Thanks for the idea Howard, but I have read on a couple LS1 forums that the Purple is not so good for them.
I will do it over the next couple weeks and let you know how it goes.

Thanks to all for your help :)

I found in my searching trans fluids for a VE some dont have a very high temp rating, so if your driving around the street with the odd squirt should be fine with dex3, if your going to push it id go with the royal purple or iv put redline D4 in a couple of boxes, its a bit higher temp rating, found in the TKO its a little stiff when cold, but comes good quite quick and has been fine in a t56.

Redline D4? What brand is that.
I read that the royal purple was not a good option due to its weight. If you are recommending it I gather they make the correct fluid. Which one is it?

The car is used on the street, but is a toy if you get my drift. Track will be a definite once it's all sorted and it proves it's self to hold together. Nothing over the top though.

I've run Castrol Transmax Z since 2006 in my T56. Gearbox has been fine and shifts are nice & smooth, although I have nothing to compare it to since I've used nothing else in the T56. It's what Mal Wood recommended to use.
