318 MAX fuel economy builds?
What is involved to get the computer transmission connected and controlled in a vintage car? I got an A-500 with the lever kick down and will control it with fully adj pressure switches and vacuum kick downs for both the od and the lock up so they drop individually rather than losing both simultaneously like some are hooked up.
You can't use the factory pcm to *only* control the transmission because it wants too much data. Well, I suppose it's possible, but by the time you put in the effort to set up a vehicle speed sensor, throttle position sensor, crank sensor, and maybe a MAP sensor you might as well go full EFI.
And if you want a full EFI engine and computer controlled OD transmission in a vintage Mopar then the Magnum swap so obviously the way to go. It's a drop-in setup anyone with some knowledge of automotive wiring, the factory service manual, and access to Google can do themselves.
There are a some standalone controllers out there that will manage the 4Xre and 4Xrh transmissions on a carbureted engine. I just found this, but I know there's at least one more I can't find right now:
E-Trans Control
If you're building an LA engine (or any engine) for big power EFI you can use the Holley Terminator, which will also control the OD trans:
Holley EFI 558-473 Holley EFI Transmission Control Harness - Chrysler 46RE
But the standalone controllers aren't cost effective if you already have an RH transmission like your A500. Just use the pressure switches and vacuum switches like you're planning to do. They work fine, albeit not perfectly. I'll explain "not perfectly" in a separate post.
