ECM

I'm rebuilding my engine and running it on a different ECM. Is the transmission controlled from the stock computer on the truck?

Is this for the 1990 in your profile? Yes, the engine and transmission control is all in the same computer. You haven’t said what transmission is in your truck or what computer you are planning on using.

I've not picked out a new ECM. I'm thinking about going with one from Holley, I want to keep it EFI. I haven't had a chance to see which trans it has yet. I think it is a E4OD.

If you have an E4OD it is the easiest solution out there. Even if you have an AOD it is still a very good product. Several folks on this forum are using them.

The one that rla suggested retains the OEM system. You need to determine if you want to keep the stock EFI system or go with an aftermarket setup and still be able to control the transmission (if applicable).
