Sorry for the late reply, I don`t get on the computer often, but back in the day at the Chrysler dealer I ran, we would rebuild 727`s and 904`s in house. We would also rebuild all engines providing their was no block damage also in house, the same held true for carb`s, steering boxes and rear`s. I never came across an 833 that had to be rebuilt or replaced all the years I was with Chrysler, but had I, policy would have provided an exchange unit, new, not reman, and the numbers on the new case would not have a paper trail to the car it was being placed into. Alan is right the 833 trans he has was either bought over the counter or it was a replacement under warrenty.
