I hope I'm in the right place for this question. I have to do a transmission swap on my 2014 es350. If my original tcm is good, does the new transmission valve body need to be flashed? Or should I be good to go. Thanks!

 

What happened to your transmission? Are you going to be doing the swap? I don't know if you have to do any electronic trickery after the swap hopefully someone else knows the answer.

 

I think a spring clip malfunctioned, metal pieces in the pan.
