Default 2J/SC400 auto trans prob

I have a 2J in my SC400 and im running an auto trans. The harness was done by Dr. Tweak and I do not have the cruise control connected (if this makes a difference with the 2J/SC400).
I am on a Mines ECU for an auto trans.
The car will not go into overdrive. I checked the trans and the solenoids and everything is fine. It drives in all gears but no overdrive.
Any suggestions on what I should look at or try?
thanks

I believe it is like the check engine light for the A340 transmission. An error code is stored and tells you there is an issue on the tranny. You need to pull the code so you have an idea what is wrong.
