4L80E conversion questions
I've been doing more research on my new transmission plan. I was driving an SMG M3 today, which got me excited about the whole paddle-shift idea. I really like the idea of the 4L80E with the TCI control unit and Steve's shrifter. There are a couple things that I have been trying to figure out about the electronic transmission swap. How does the TCU get an engine RPM signal? Does it sense torque converter speed, or is it wired to the ignition system? I have a full MSD system (billet distributor, 6AL box & blaster coil) if that matters. Also, what is the best option as far as speedometers go? I have a mechanical autometer speedo right now. Should I go with an electric speedo, or use an adapter to use a mechanical speedo? Thanks,
Andy
