Hello Jorge! Rats, I think your tranny is doing exactly what I want mine to. The difference is that mine will drop out of lockup as soon as I stop accelerating, just crusing down the highway at 65-70MPH will NOT keep it locked up. Even if I push down the throttle some to lock it up (and I have to push it at least a quarter of the way down), as soon as I let up a bit (or push the throttle down further) it unlocks. Without pulling the tranny, I think changing the lockup control solenoid is the only other option I have at this point. Thanks much for the advice guys, I appreciate it.
