Introduction:
Hello, my name is Zach. I'm new to this forum but I wanted a place to document my issues in case someone else has the same issues down the road. I also have made up two stories. One if you want to know what this thread is about and one explaining all the details about the problem at hand. I hope I can keep everyone updated and help someone else one day with the same issue.
Prerequisites:
- My truck is a 2017 RAM 1500 Limited with a 5.7L V8.
- My truck has about 110,000 miles on it.
- The transmission pan/ filter and fluids were replaced 06/2020.
- I replaced my battery about a month ago (Early Feb 2023).
- This is the first winter since owning the truck that I haven't parked in a heated garage.
Short story:
I replaced my battery and ever since then when it gets really cold outside (below 0°F) my check engine light turns on and when I put my truck into "drive" I got an error message that reads "Shift to P then Desired Gear".
Long story:
I live in MN where temperatures can dip pretty low and I park outside in the elements. About a month ago I went to go start my truck and it wouldn't turn over. I would press the button and nothing would happen. I then hooked up a portable jumper and got it going. Let it run for about 30 minutes before turning it off and walking away (thinking maybe the battery just needed to be charged). I came back the next day and the same issue occurred. I then again jumped my truck and drove to the auto parts store to purchase a battery (more specifically I drove to Advance Auto Parts and purchased a DieHard Platinum AGM Battery: H7; https://shop.advanceautoparts.com/p...for-high-electrical-demands-h7-agm/10210826-P). When I was in the store I didn't turn off my truck thinking if I did it would die. Once I drove home I pushed the fiance's car out of the heated garage and started removing my old (original) battery from the truck.
As most of us are aware changing a car/ truck battery is easy. About 30 minutes later I had the new battery installed and ready to go. I started up my truck and all seemed well. This is where things started to get weird, when I turned my truck to drive immediately the check engine light turned on. I got an error message that read "Shift to P then Desired Gear". I had never seen this before so I did just that, shifted my truck into 'park' and then back into 'drive'. The same error message came back up. Frustrated I then did it another 5-10x with the same outcome every time. So next I just turned off the truck for 30 seconds and turned it back on. Still the same thing. Dumbfounded I went to the internet. I read a form that said sometimes the truck needs a full hour disconnected from the battery to reset whatever. So I said what the heck and did just that. I disconnected the battery and went inside. About an hour later I came back out to the truck and reconnected the battery. Got back in, said a little prayer, and started it back up. Same issue "Shift to P then Desired Gear". Frustrated I went back to the internet. I saw another form that said it could be transmission issues. Scared and with nothing left else to try I figured I'd let it run for 5-10 minutes to get everything up to operating temperature. After the transmission temperature read about 70°F I put it in drive and to my surprise, the truck started to move! Confused about why it was now working I went and did some close-to-home errands for about an hour. I did think to stop off at the auto parts store again to read the codes on my truck. I did get a transmission control module error code of "P1B14-00 - Park-By-Wire - Unintended Park Position". Strange, I tried to clear the code but it remained a "permanent code". I figured since my truck is running that maybe it would just go away on its own, and it did. The next morning when I went to start my truck no more code. Not a single issue came up after that so I figured it was just a glitch in the computer system and since forgot about the issue.
Flash forward to today. For the last two days, I haven't had to go anywhere. Leaving my truck out in the elements while temperatures dipped down to -11°F. I mean it was cold but not that cold. This morning I did the usual, I remotely started my truck for about 10 minutes. Not long enough for all systems to get to ideal operating temperatures but enough to get the cab warm for my drive to work. When I got into my truck that same old issue came up. I immediately noticed the check engine light was turned on. When I went to put my truck into "drive" I got an error message that read "Shift to P then Desired Gear". Remembering what worked before I let my truck run until the transmission temperature read >70°F. Sure enough, it moved again.
Plan:
Next week I have a scheduled appointment at a RAM dealership for them to diagnose the issue. In the meantime, I plan on letting my truck warm up to operational temperature before going anywhere.
What I believe could be the issue:
1. Transmission fluid is low. I did replace the transmission pan/ filter and fluids in 06/2020. Maybe I never filled the pan up enough? Maybe there is a leak? Maybe my truck is temperamental and doesn't like being cold?
2. The passenger side door latch sensor needs to be replaced. It doesn't indicate that the door is "open" on my dash but the door does have some issues. When you normally walk up to your truck with your keys in your pocket the door will unlock. Or say you again have your keys in your pocket and you press the little button on the door handle, it should lock. It doesn't do either of those. I do know that if your door is open the truck will get the same message. Maybe since replacing the battery it triggered something? Who knows.
3. The transmission parking pawl needs to be replaced since it's getting stuck in the park position.
4. Faulty Park Release Solenoid
5. Faulty Park Hold Solenoid
6. Park Hold Solenoid harness is open or shorted
7. Park Hold Solenoid circuit has a poor electrical connection
8. Faulty Transmission Control Module (TCM)
9. ECU needs to be reflashed
Below I attached some supporting files such as:
- 02_2023_ScanReport = The original scan report from when this issue first came up
- ShiftDashError = The error code that appears on my dash
