What do you getrag experts think of this? This is the 2wd getrag from a donor truck for my crew cab. It is a reman unit, unknown miles, I only drove the truck off the trailer and around the block a few times ( no bed, plates, lights etc). During the test drive, it was quiet, shifted good up to 4th gear, never got it fast enough for 5th gear. No grinding in gears. I just now opened it up for an inspection, drain, clean, new silicone for the top cover and pto covers etc. Crew cab is dying to get out and run. How bad we looking? And what is this piece called anyway? Thanks. BTW, the crack in the piece is pretty much center in the first pic, the second pic, I rotated the input shaft a tad, the crack is to the bottom in the pic.
