I have the 3-5 poor shift characteristics. So I am going to replace the direct clutch and EPC solenoid. Along with the dummy plug upgrade.

I have read that I don't have to remove the valve body to install the EPC solenoid. Correct?

Is there anything else I should do while I'm in there?
I already have the 2008 pan and filter update.


I'm getting my stuff from Ficmrepair.com.
