Need some questions answered on doing a th400 swap in my 07 nnbs Silverado. Who makes the best crossmember for the th400 swap in these trucks 07-13? I picked up a FTI Th400 for a good price and plan on doing the swap when I install my f1x procharger. What needs to be done in order for the speedo to work with the th400? Also it has a full reverse manual valve body with transbrake so I’m planning on running a ratchet style shifter, but what needs to be done to the column shifter in order for the truck to start? Thanks for the input guys!
