Hi,
First post from a 4 year reader. We own an 09 MDX that is experiencing some problems. I will try to describe the situation.
2009 MDX with 95,000 miles.
2 months ago the wife reports a check transmission message although the car drove fine.
I check the fluid and it appears ok. I remind myself to change the fluid as we bought the car second hand and it's most likely due.
Our busy lives rock on until a few days ago.
The wife calls me and the car will not start.
I see corrosion on the post of the Optima battery that is now 40 months old.
I attempt to remove the negative terminal end and the entire post leans over and partially detaches from the battery!!
Of course the battery is out of warranty and I replace it with a traditional wet cell.
The car still will not crank over so I do not have time to deal with it and a reputable local mechanic gets it.
I flat tow it less than 1 mile to the mechanic. In neutral with the key on of course.
He replaces the starter and all is well.
Now he calls me and says the car will not go in reverse and a check transmission light and code P0874 is in the info center.
It will drive in forward gears although it shifts extremely firm. I drove it 1 mile home. He (we) cant find a connection to a starter replacement and trans problems. He looked it over as have I and see no harmed wiring etc.
So P0874 appears to be a 3rd gear PSI switch. My local auto store will have one in the morning and I have already remove the original and started the car for 2 seconds to flush fluid from that port area.
Anyone think the repetitive battery connecting and disconnecting has harmed the electronics?
Can a P0874 even relate to reverse?
Does the trans go into a limp or self defense and max out the line PSI and eliminate reverse?
Anything I'm missing?
HELP!!!!
If you read all that...thanks have a drink on me!!
Matt
