I'd like my truck to eventually become an RT clone and I know that the 46RE is what the RTs use. The problem is that I don't have the funds to do a complete v6 > v8 swap, with my mileage hitting 170k I believe tranny trouble is right around the corner, but I believe my engine will run for much longer. Therefore I feel like I must take advantage of this cheap RT-compatible tranny, keep it in mothballs until my tranny starts to die, and then use it with my v6 for a little while until someone on this site finds never-used, straight-from-the-manufacturer 360s for a $1000 for the next part
Also, I wonder if the 42RE would be easy to find in their systems. I gave the sales rep the number posted in this thread and assumed that was why he found it so easily.
