Well....hello again! 4L80E Question

[Patch]

Hi all.....been gone a while...but I have a follow up question concerning a 4L80E I am putting in my 90 K2500 Burb. I pulled the transmission and transfer case out of my donor 91 K2500 burb....I was going to pull the factory harness and controller for the 4l80E but have decided to just buy an aftermarket controller. Who in ya'lls opinion makes the best stand alone controller that is somewhat reasonable $5-650 and will i need ANYTHING from the 91 except the tranny/transcase, crossmember (just because it's still bolted up) and the dash cluster for the electronic speedo? Will the aftermarket controller and harness take care of all of the other needs? Thanks in advance......Pat
