What is the best way to get an overdrive auto in a 67 Barracuda?

Do you have linkage that hooks to the carb linkage so the trans knows when to disengage the lockup? And when to shift etc? The Extreme website states the stage 2 trans shifts at 4500, I left an email and tried to call Lonnie but I hear he's a one man show and very busy, I would hope it wouldn't shift at 4500 under normal driving conditions ,I wasn't sure they weren't set up with a manual valve body.

I think the OD hook-up is explained as you were writing this. My Stage 2 shifts at 6500 rpm when the throttle is wide open. No changes other than that's how it cam from Lonnie. He is a good man. This trans makes my car quicker and faster than I would have ever expected. It's the best transmission I've ever driven, except the high dollar computer controlled AMG Mercedes stuff.
