I had several transmission failures on my Colorado. The transmission shop told me to put an off the shelf replacement tranny in it. They said these companies have thousands of units in the field and don't like warranty problems. They have figured out all the weak points and build them to last. I went with a rebuilt unit, added an external cooler, and have had no issues since.

Holy cow those prices are reasonable, I added the link to my favorites for future use.
