So I have a flashing OD light on the dash (no check engine light). Attached my code reader and received 2 codes. 1 for shift silenoid A and one for silenoid E. In doing some investigating I read that it is uncommon for 2 silenoids to go out at once. I guess my question is how true is that. If so should I have the connectors changed before having the silenoids replaced. Or what should I do? Any assistance would be greatly appreciated.

car registered several transmission related solenoid codes. Changed all of them out. Did not solve problem until the ECM was replaced,this seems to have remedied the situation.
I do not know if this will be of any assistance. I just know it worked for me.

Did you run into any security system issues or it was a straight ECU swap nothing else needed. I've read so many conflicting stories on this for your year.

Help me out....would you suggest changing out the ECM before messing with the those 2 shift silenoids. Also if and or when the ECM is replaced would I need to have it programmed or flashed?

Check the resistance of the solenoids from the connectors at the ECM in a manner similar to this thread https://www.clublexus.com/forums/es-...-solenoid.html. That way you check the wiring and the solenoids. According to the 2001 repair manual, if the resistance passes the problem is the ECM. What are your specific error codes? I'll see if I can track down the specific pins for you to test.
