How do you like the 4L80e? Did you use a single or triple clutch?

The guy that's building has done this swap many of times on our Blazers. I just couldn't remember all the details he went over with me to make it work and support the TQ my engine is going to put out. I'm going to try my best to document the entire build so others can reference it if needed.

We're going to keep the engine in the stock location and move the tcase back and use a custom driveshaft.
