I really appreciate all your help. I like to try to understand the underlying cause and related issues. The one thing that I need to know that you didn't answer is if it's a better idea to unplug the shift solenoids for the time being and leave it in default 3rd gear mode until I fix the problem by swapping trannies or fixing any related electrical problems. That's kind of important to me so if you could answer that last question I'd be very grateful. Thanks again for sharing your knowledge with me.
