Beep code?

Hey folks.
A short while ago I moved my bus and it ran perfectly. 92 Detroit diesel Allison transmission transit bus conversion. Started it up and I got a check trans light come on when I press a button other than N and won’t go into Drive Reverse 2or3. weird thing everything is fine in 1. . Had someone come look at it. They said code 23 shift controller. I bought a refurbished controller on eBay, installed started it up and still having the same problem. Only now the check trans is also blinking and beeping even in N. Beeps 5 times then 3 times. Repeatedly.
Anyone have an idea of what is going on?

I found this over on the FMCA site:

Welcome to the FMCA Forum.

Have you checked for Allison diagnostic codes?

With ignition on, engine OFF:

Hit the up and down arrows on the Allison shift pad at the same time. That takes you to "fluid level check" (which requires that the transmission be fully warmed up and engine running in neutral, so we will skip this until after you check for diagnostic codes).

Hit the up and down arrows a 2nd time. This takes you to diagnostic codes. It will show d-1 and then a two digit code. If no codes it will show d-1, - -.

If there is a d-1, after copying it down push the mode button to go to d-2. Continue until you get a d-?, - -.

To exit, just push "D" or simply turn off the key.
You can get the diagnostic codes from your Allison owners manual or on Allison's website.
