Been hearing some great things about this controller! Eliminates the need for the TCM but you have to shift manually. Lots of write-ups on Jeep websites.
I know many have expressed interest about the AW4 behind the 258 as it's a bolt on (with the late flywheel) and holds up well to abuse. I am actually considering bolting an AW4 up to the 360 in my FSJ and researched this as one of the better and more affordable options for controlling it. Really good feedback on different websites about the customer service as well.
Enjoy!
