Rebuilt Transmission or Transmission repairs, loss of reverse in 4L60E

I’ve a passion for Cars and keep looking for information on it. Today, I checked if I could find more info by entering ‘GMC Suburban’ in Google and found this:

I have been asked many times why has my Chevy Suburban lost reverse all of a sudden and only seems to have 2 forward speeds and make a racket if I drive it more times than I can recall. … Personally the updated factory one is what I put in my GMC truck and my wifes Safari van….

I tried several more searches on ‘GMC Suburban’ but after some time I got lazy, gave up and posted this entry to ‘GMC’. Still, I think it was an interesting time.
