I have a 2008 Chrysler Town and Country Limited that's gone

This answer was rated:

I have a 2008 Chrysler Town and Country Limited that's gone into limp mode. The codes that it is currently showing are:P076A Shift Solenoid H
P0562 System voltage lowMy question is can a bad battery or alternator cause this van to go into limp mode. Is it possible for this to be the cause for limp mode and for it to have nothing to do with the transmission.

If it is going to be an issue with the transmission, where is the best place to start since what I found seems to point to several different issues it could be.

Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Always check the battery and charging system first, then move to the component that is lacking accurate power and search for a bad ground if the power source is too low.

If all this is good, then read below.

Here’s the sequence of events I follow:
Check fluid level and color. Make appropriate repairs.
Check shift solenoids with a scan tool in bidirectional mode if
applicable. Shift solenoids are inside the transmission and this is
the easiest way to check them.
Drop pan and inspect for excessive metal shavings inside pan.
Check valve body and clutches visually.
Hopefully you may not have to go this far, maybe you just were a
bit low on fluid.

How do I know what component is lacking adequate power?

The that was set. Complete system voltage OR trans solenoids voltage.

you're saying the fact that it was showing the code for shift solenoid h means that that's the component that is not getting adequate power correct?

If your battery and charging system are working properly, then you can have a bad ground in the shift solenoid circuit.

You don't have a wiring diagram of that shift solenoid do you?
Customer: replied 5 months ago.
When will I need an actual multimeter for that or can I do it with a regular voltmeter?

Nope, but the shift solenoids are all inside the trans anyway. You can't get to them without taking off the pan. They are located right on the valve body. A diagram isn't needed anyway once you see the plug. that's your testing point unless you want to do it the easy way with a scan tool.

I'm ready to be rated now for additional assistance, incentives:)

I've got a regular cheap scan tool that will send me the codes. What kind of scanner would I need to pinpoint the problem?

Please read last reply.

Thanks again, Ron

Alright Ron I'll give it a shot. Thanks for your help.

You bet, thank you too.

Most parts stores will loan you a good scan tool for just a deposit and that will get the job done for you.

Alright Ron, had a battery with 2 bad cells. Bought a new one and that solved the low voltage problem. So I'm going to dig into the shift solenoid pack tomorrow morning, any tips?

You may have it fixed already. No tips, just testing.

Thanks again

Ron
