TCC code : p0740

New here - I have a Honda Civic EX 2002 , I had my check engine light come on I got it scanned it came back as a p0740 , said it was the TCC. I replaced solenoid “A” well from what Advance Parts labels as “A” which is top of the transmission under the air box. I got part “B” from them and can not find any place that it goes?


It is not the linear solenoid as it does not have both connectors or the screen. I am trying to figure out where solenoid “B” goes. The box from advance parts is labeled as the “at control solenoid”, if that helps.

I believe P0740 is considered the transmission death code. Needs a replacement transmission.
