OK, so this is definitly NOT true. There is an electrical connector on the top that is not on the older one, and the body of the newer one has a larger circumfrence, leading to the tailshaft/T-case mount being completely different. Not a biggie since the tranny had to come out anyway.
With that being said, I now need to find a tranny. Based on research, I think it is a 46RE, but would like to know if someone can confirm that.
Finally, if anyone knows where one of these is that is inexpensive, please let me know. My son is at college, and I am tired of his truck sitting here and listening to him. The problem is that he doesn't have a bunch of money sitting around, and I can't just bankroll this for him.
Thanks in advance for any help,
