Louis-Alain,
You basically covered it nicely.
The only other difference is that the 4kq tranny has small output flanges
while Ur-q has the large ones, but that's just a matter of swapping out of
your original. Also, starting '84 the bellhousing has a notch to clear the
new style MC/3B/AAN flywheel sensors.
Hope this helps.

Swappable, sure. Physically at least.
But there is some difference:
- Final drive ratio, 3.89 for the urQ, 4.11 for the 4kq.
- Some gears are different, as the 1983 urq has very short first and second
gears, then a hole, then 3-4-5 are closely spaced. To resume, urq 1983's are
6 speed gearbox missing the 3rd... 4kq are better, more envenly spaced.
I forwarded this message to Martin Pajak, he's THE reference for this kind
of question.
Martin ?
