' The AW4 was never integrated into the ECM/PCM.  It's still a seperate module
' but it moved over to the drivers side above the go pedal with the change to OBDII.
' 
' 1998 was a bit of a change over year for the AW4 tranny and TCU.  A front
' input speed sensor was added to the tranny and the rear sensor changed a bit.
' This should work on 98 and up, but the best bet is to match the color of the
' connector which changed color and shape with the change.

" I've driven these - they last a good long time and
" shift great.

my gf has an '01 xj with one.  my only complaint [besides preferring
sticks] is that it doesn't have separate 1 and 2 detents, because
there are several times i've wanted to hold it in 2nd, but if i slow
to below 25 it slams into 1st then won't upshift.

since this is an electronic box, in principle it should be easy to
make a substitute that does what i want.  dunno how the column handles
detents, but gms with the saginaw have p-r-n-d-3-2-1 patterns...
