I have a TL and a MDX. both are due for new pressure switches. after looking on here and there, I am more confused as to what part number is right. At this moment I have 10 different numbers. and just as many different prices. I tried matching with the actual pressure the each unit put out, but that number is just as elusive. I need 4 switches for both vehicles. are they all the same? I called acura, but that guy Is just in the foulest mood. such a bother for me to be calling him. anyways a compiled list would be awesome or just tell where to find the RIGHT part. thanks y'all !



2006 TL base
2008 MDX loaded

 

I guess that you're referring to the automatic transmission pressure switches.
I have a 2007 MDX and I changed 3 tranny pressure switches.

The one located behind the driver's tire (you have to be on the ground to get to it) is part #28610-rke-004

The 2 located on the top (ish) of the motor have the same part number, 28600-rke-004

Each pressure switch needs a washer, so that's 3 ea. part # 90471-pw7-a00

These 3 switches have fine treads, are aluminum and and attach to plastic switches, so I can not over emphasize the the torque setting is 14 ft/lbs and that is about the same torque as needed for spark plugs.

I never cross referenced the TL numbers.

 

thank you so much. after researching, it becomes very confusing. I appreciate the clarification, I wonder what would happen if you was to get them mixed up?

 

They engage at different fluid pressures, so don't take all 3 of them out of their individual parts bag at the same time.
Take them out one at a time. The parts do not have any markings, so you are completely depending on the part number on the OEM bag.
Use the Acura online parts diagram page, to install the correct part number into the correct location.
