My wife got a check tranny light followed by the OD shutting off. Then she got a check engine light. She stopped at the parts store and they read the code. It is PO775 "pressure control solenoid B circuit malfunction" . Anyone else have this problem and what is the fix?

 

Sorry, it's a 2002 merc Mountianeer, auto with a 6 cyc.

 

That code is indicating a mechanical problem with a solenoid. I would replace the solenoid block. I have not ran across that code before but I do know that those solenoid blocks have problems, I have replaced many of them for a number of issues.

 

Thanks, jk080. Do you where the soleniod block is located on this car?
Thanks again, Jay

 

Bad result. The trans needed to be rebuilt. $2100. at an indy garage. The dealer wanted 3500.
