Welcome to HAF.
Might try checking for stored codes in the ECU and TCU - just need a paperclip to jump the service connector.
Do you have a volt meter or test light to do some tests?
Any updates, please start a new thread in the General Tech section - include all info of what has been done/tested/replaced and the info on the car. We suggest members put it in their signature so they don't forget to tell us what kind of car they are working on.

My child arrived just the other day, he came to the world in the usual way
Heaven is in the palm of my hand and it is waiting here for you, what I am I suppose to do with a childhood tragedy
