i'd be interested to know what years the original apps were for all
those parts you got, and what year and original gear your grem was.

generally a '91-8 wrangler or grand cherokee are considered easiest.
they have a centered 'normal' fan which the cherokee/comanche doesn't,
and these years have the best head.

sticks are rare on the gc.  the first year or two had an aisin-warner
aw4 auto, which doesn't have a lot of torque multiplication but is
very efficient.  after that they went to a tf 42re, an electronic 4sp
mopar auto with great torque multiplication.

auto on the wrangler is also mopar, a tf999/32rh/32re.  i believe it
went electronic with the obdII ecm, in '96.

stick with either, if you can find one, is an aisin-warner ax15, a box
with a very good rep.  bad for a light car, it has trucklike ratios,
and you'd have to get one from a 2wd cherokee.  if you can find a 
late-'80s/early-'90s turbo supra r154 box, it's a sibling with much
better gears.  the pilot bushing and clutch spline are different but
can be handled, and it fits the ax15 bell.

probably most satisfactory would be an advance adapters custom bell
and ford svt t5, a great shifting box.  move the shifter forward with
a gm s-10 extension case, replace 5th with a bw aftermkt 0.8, and add
the 5speeds.com cluster stabilizer.

while you're planning - build that 4.0 into a 'stroker' with a 258
crank.  with not too much work you can be approaching 300 hp with well
over 300 ft-lbs, still smog legal...  see the 'strokers' group at
yahoogroups.com.
