Default Paging Tranny Tom.

I've got an '06 Durango at the shop that runs fine but will not move. Code scan comes up with a single code, P0876 underdrive pressure rationality failure. I did some reading but nothing came up where the vehicle failed to move but instead went into limp mode. I was going to check the line pressure but the pressure tap is just about kissing the catalytic converter (brilliant!). I did pop a cooler line and fired the engine up. Zero fluid movement but trans has plenty-o-fluid in it. The fluid also looks fine. My thoughts are that the converter took a dump. I know the pump could be at fault too but I've never really seen a front pump fail instantly.

I'll be dropping the trans on Monday but I thought I could get some input from you Chrysler product guys that may have seen this type of failure before.

I'll be pulling the trans today to inspect the converter. If anyone has advice, please call me at 989-662-7785. Thanks in advance.

My brother n law Durango did the same thing last year. It was the solenoid pack. If I remember right he said it's located under the valve body.

Here's a short link talking about the problem.

It's most likely the pump has taken a poop. The no fluid through the line isn't a good sign lol. That code can be set by a faulty sensor, but i don't think it will cause the no movement.

I thought about that but there is no fluid movemnt or line pressure in the trans. I don't believe that would be controlled by the solinoid pack. The front pump should keep things moving as long as the engine is running. Somebody told me converter failures are common on these trucks.

The owner says the truck ran fine when parked. Tried to drive the next morning and nothing. Have you seen pumps fail like that? Should I pull the pump and check clearances or do you think it will be pretty obvious that something went kablewy when I pull the pump?

As far as the code goes, I think that's just due to no line pressure.

I have not personally seen that happen, but it isn't impossible. Is it full of fluid? Without being there it is hard to say what is actually going on. Usually 0 line pressure equals bad pump or broken converter hub.

I had a chevy van that the filter was plugged and looked like it had moisture in the pan. When it was cold out it would freeze the moisture and plug the filter. Sounds weird but i flushed the fluid and changed the filter and never had the problem again.

I got a late start on the vehicle today so the trans is not quite out. This vehicle is super easy to work on and there's lots of clearance to get my hands in places to unplug sensors.
