Transmission System: P0873.
Did a quick search online and pointed to transmission pressure switch. But which one? I have 2011 MDX.

Immediate question is it safe for the transmission while driving temporarily with this issue. Of course I need to get it fix ASAP.


Who can tell me which automati transmission pressure switch below for which gear from this diagram


Thanks

 

perhaps the 1st gear? since you're moving from a complete stop

 

based on the code P0873 , the SM said it’s the 4th clutch pressure switch:

 

well there you go.
good job, victor on figuring it out

 

Is this the actual pressure switch for 4th clutch?

 

No! Front of the trans. Look closely at the picture that was posted.
