TR6060 trans questions.

[Jethrow]

Hi everyone.

So I have a TR6060 6spd man trans bought new for my cobra replica. It came with a oil cooler kit which I had to mount up.

Now as far as I know, these transmissions are rated 'filled-for-life', suggesting an oil change is never? required. So my question then, is when I install the oil cooler, would there be enough oil in the system to fill the cooler, or do I need to add more? And if I do, how do you check the oil level, and if required, add in some more oil?

Also, for a quick hydraulic clutch question, can the oil line between master and slave cylinders by 3/16", or does it need to be bigger? I see that the original HSV line is 1/4".

Thanks.
