Hi, I have a problem with my wifes 2010 Journey. It will rev really high (4-5k) but not feel engaged then if I let off the gas it will go down to 2-25k and then I give it more it will go back up to 4-5k. I can get it up to 55mph at best. Ran the cel's and there were 6 total. Some I'm thinking have nothing to do with this problem.
1) P0571 Brake switch
2)P076A Shift solenoid (thinking this one makes the most sense)
3)P0406 Egr position sensor
4)C0077 Tire pressure ??
5)C1000 Brake pedal switch
6)C107C Another brake switch code

Any help is appreciated. Thank you

 

More info on my problem....when I drive it for say 10 minutes it won't shift out of first. So not sure what the problem is other than the shift solenoid.

 

How many miles on the odo?
Has maintenance been done on the transmission?
Other then that I would say the solenoid pack is a
good place to start.

 

Thank you so much for the reply. I shamefully admit we have done no service to the tranny. It is throwing a P076A CEL. Replace that and replace the filter and fluid id a good place to start then. Thanks again and any more input is appreciated

edit- 120000 on the odo

 

We have the same issue with my wife's as well, the dealership could only find an issue or codes for the oil control valves....would those effect that issue?
