It will be a much improved transmission over a T5 NWC box. I've not seen one, but from reading the specs, it is probably more like the modern Magnum tranny, but smaller, lighter duty, etc..
If you've ever shifted a Magnum (which is totally redesigned and not the same as the older TKOs - you feel a really nice smooth engagement, excellent). You have three different shifter locations on the TKX, so with the forward mount, should work pretty well in a Hotrod.
Lastly, you have a whole range of gear ratios - I like the close ratio setup with the .81 overdrive - great setup for one of our cars:
