Will 05 Colorado 3.5l V6 tranny work in 05 Silverado with 4.3l v6. I believe the flexplate has to changed to accommodate the TC hole spacing...just wondering about functionality...?? Any thoughts/advice..??

 

I guess the question really is whether it is the same transmission in both vehicles? I am going to guess that they both used the 4L60E, in which case it may be a direct swap. BUT if they were different, then the wiring harness and computer won't work properly when you put the transmission in the Silverado.
