transmission popping out of park.

[rjjack]

My neighbor is a firefighter and he has now responded to Two incidents where dodge trucks have been left running and in park and the trans popped into reverse running over the driver. His station chief had his dodge back down his drive and cross the street hitting his neighbor house. Is this just a worn out part that can be replaced easily?

I have no facts to back this statement up, but here is what I heard from a dealer.



When I asked why my 2007's horn honked when in reverse and the door slightly open, I was told that Dodge was sued when a person had the door open, was behind the truck hooking up a trailer, and it went into reverse. Not sure if its true, but if the door is shut in reverse no horn. A REAL PITA when trying to back a trailer and you crack you door to check something and it wakes up everyone... .

rjjack,



Welcome to TDR.



EVERYONE will tell you that I don't know jack about A/T's and they are right. But I did try searching on 3 Gen threads with PARK in the title, see above. You did not give us a year to work with, more details will help TDR members reply effectively.



Good luck.

Thanks
I don,t have any info on m. y. just the story from the firefighter. My 06- 2500 has become hard to shift from park. I now shift to N and set the PB i then shift to P. it seems a lot easier to then shift from park. no bang and I don't cringe anymore.

rjjack,



If you can use the search function , search Park in TITLE for 3rd Gen Eng and Trans, read some of the other PARK threads.



Good luck.

I would guess that 99% of the issues around coming out of park are simple operator error. Park is simple a hook that drops into a deep notch of a gear on the output shaft.



The high spots are as wide as the notchs so imagine what happens if the pawl sits on the high side instead of a notch then starts rolling. One can feel the pawl enage when the stress goes off the drive line. If you don't feel the bump be VERY careful exiting the vehicle.



The totally unbelievable thing is people get run over by a vehicle that they started then exited. Guess a parking brake and its operation is another lost art of civilized society. :-laf

I can see getting knocked over by the drivers door and then the front tires rolling over body parts. if the vehicle operator runs himself over he should at a minimum qualify for the Darwin awards.

I emphatically agree!

I have never in my life had a car or truck slip out of Park or known anyone who has experienced it. I once had a Furd Ranger demo roll out of my driveway, cross a residential street, and bump into my neighbor's mailbox. Cause?

Factory defect? Faulty engineering? Worn part?

Nope, operator error. I parked it in neutral (manual) and didn't set the parking brake. Stupid, and embarrassing but I could only blame me.

The dumb backup/door open/horn and light show that was forced on '06 Dodge owners was because some dumbass with his door open backed over something and tore his door off then blamed Dodge.

For the poster who mentioned trouble shifting out of Park:

The issue of a truck hanging in Park, not wanting to come out of Park, is an entirely different issue. That happens because the crappy little microswitch that operates off the brake light switch and extends a tiny little plunger or pin to lock the shifter in Park unless the brake pedal is pushed is a common failure item. Just remove it from the column, leave the wires attached, and zip tie the switch to the column. Then you can pull the shifter out of Park without stamping on the brake pedal.

My 05 took off on it's own in reverse when it was little more than a year old.

It was started by reaching in the door and not climbing into the seat and the only thing touched was the key.

If it was not in park why did it start? No it was not in neutral either.

It was after work and I fired it up while my excavator was cooling down. While walking to my excavator I heard a loud crash and turned to see my truck aprox 80 yrds away in a deep drainage ditch. Had to use the excavator to pull it out of the ditch because it would not do it on its own.

This **** is real and anybody that doesn't believe it should get their head out of their ***. Do a search on MSNBC they did and article on it a few years back.

My service manager thought I was nuts until he went to a service managers meeting of some sort and he said that there was 3 other dealers with the same story.

This truck was all but impossible to get out of park before this and now the dealer adjusted everything they could and it has worked perfect ever since.

LMAO!!! :-laf:-laf



Like I said, operator error.

Speaking of folks who have their head in private parts of their body, I don't get my news from the propaganda news media. I have doubts about the knowledge and reasoning power of anyone who does.

I can't understand why anyone who has ever seen a park pawl would trust it with their life. (And, to be honest, I'm amazed there aren't more problems with sheared pawls - a testament to pretty good design. )



Maybe part of the problem is nobody calls it the "parking brake" anymore - it's an "emergency brake", only for use in emergencies.

This is a known issue with certain model years (including mine). I received recall notice from Dodge to bring the truck in and have re-flash which installs the backup horn feature. (I think the headlights may flash as well)... if the system detects some combination of conditions (engine running + not in park + door open or something like that. ) I didn't have the recall performed because it really doesn't "fix" any issue, and also the beeping horn seems like it would be a real pita in some situations (as others have mentioned).

I did find a TSA (or whatever the entity is) report online, perhaps on this site or elsewhere on the web. I think I have a PDF of it somewhere- would have to look. PM me if someone wants, and I'll see if I can find it.

IIRC, the core of the (technical) issue is that the shifter can be unintentionally left slightly out of park (but not all the way in reverse), and / or this can also happen if the shifter cable adjustment isn't quite right. Again, that can be due to user error not firmly placing the shifter in park, or due to being out of adjustment. What happens (again iirc) is that the reverse fluid circuits slowly fill up, then the vehicle moves in the reverse direction under engine power. It can take several seconds for the fluid circuits to fill, so there is some delay- like enough for the driver to exit the cab and get behind the truck or whatever.

I agree with rpattelle above about "anyone who has ever seen a parking prawl... "
The solution I implement is: If the engine is running and I need to exit the cab for any reason, for any amount of time, the parking brake is applied. That's not just for this truck with this known tendency...

my truck hard shifting out of park is not the micro switch. its just the truck moves slightly after i put it in park and i think it just puts extra pressure on the prawl. like i said if i shift into N. then set the parking brake. release the foot brake and then shift to P. it comes out of park real nice. I think if it was the micro switch it would still hang up.

If you shift to park with the brake set it make or may not engage the parking pawl, depends on how it lines up with the notches in the gear.



Quite likely your hard shifting out of park is probably is the VB housing worn where the detent ball sits and its jamming. It will go in fine but coming out of park it jams. Known issue on the 06+ VB's and even some of the older ones. Good news is ther eis an easy fix for it now instead of replacing the VB.

what is the fix?
