Bench press it.. neither the trans or T-case in a Jeep, whether it is the AX5 or AX15; can't weigh more than ~70 lbs.
Take the t-case out (30lbs at best) then the trans. done' plenty of jeeps this way.
Quick Story; the first trans I ever changed on my own I did this; it was a sm465 with a np 205 hanging off the back, didn't realize how heavey this combo was (200 lb-ish) it sucked..
