As I started looking into a replacement, one shop is telling me that until I swap over the rear-end from the same vehicle (2003 SIlverado), that I will continue to go through transmissions. The speed sensor and associated parts won't read things correctly, etc.

This seems a bit far fetched to me, but wanted to get your opinions...

I for one think they are full of it. There are a lot of vehicles running around with LS based engine/trans combos that are running the original rear ends.... The settings can be changed in the tune if need be to accommodate for shift points, ratio, tire size, speed, and a multitude of other parameters.
