96 Camry runs at 2500 rpm at 60 mph. I think I may have lost the overdrive gear.

Your code may not be suggesting the solenoid has failed, but it's impossible to tell until you do circuit testing. You'll have to test the solenoid itself. Test equipment must be utilized to test to see if the solenoid is being activated and then if it's actually activating.

I will test the sol. which i think may be in front near the trans. dip stick. It should be sol. 3 or sol. E as my code reads which is the clutch lock-up sol. It may take a few days because i am going on vacation and don't know if i will get to it before I go.
