Putting the DCT in P

cfung0517 · 07-12-2018, 08:29 AM

Pull handbrake and turn off the car. That's it.

I didn't read this whole thread. However, the DCT is not an traditional automatic transmission. It has a locking mechanism when the engine is turned off. The car calls that "P". The car has clutches, and shifts based on user input, or computer input.

Sure, it can be similar to an automatic. But it isn't, hence, no park gear.

Because I'm concerned the car will roll down the hill.

Are you saying the parking brake is strong enough to hold your car on a 15%+ grade??? I'm too afraid to test it on mine with me out of the car. Hence why having a "P" would be better.

In fairness, a manual transmission has the same problem.

How would you have done it if you had a manual Fxx ?

I always park my 6MT M4 with the hand brake in and the transmission in 1st gear.

IDK if that's a fair question because it's not a true manual. I like the nuance of the DCT, I just agree with those that say it should have a "P".

A properly applied parking brake is just as strong as a transmission parking pawl. The handbrake is strong enough to lock the wheels of a rolling vehicle, so holding a car standing still on a hill is a non-issue. In fact, the parking brake should be the primary system holding the car with the transmission pawl only being a back-up for safety.

For the record, I agree with always using the parking brake first, versus the pawl. However, Porsche doesn't have a problem with this. Our Macan has the PDK. The shifter works like an automatic shifter, as it should. Push the shifter into the P position and it's parked. Sure it's dumbed down, but why not? There's absolutely no reason BMW can't do this too. The first time my wife wanted to drive the F80, I said, "Okay, I'll show you how to work the shifter, and put it into Park." She thought I was fucking high.

I agree. And wheels chocked to the curb.
Just turn off car without getting out and the car goes into park.

There’s an engineer at BMW looking at the soon to be 50 pages of this thread laughing his ass off over a beer.

Mechanically, the DCT has a parking pawl just like a traditional automatic. The only difference lies in the user interface on how to engage it.

Thanks for clarifying. I'll go look up the word "pawl"now. The context clue gives me a good idea, but I'm still curious.

Not being sarcastic, I don't know much about cars, but like to learn. The problem is that there is so much lingo I don't understand yet.

Update: I see now that pawl is a latch of some sort. Cool to know.

BMW DCTs are good but not perfect. Some of the DCT complaints are valid. Not being able to get transmission out of P without the engine running is RIDICULOUS.

Had to get car towed 100 + miles cause car wouldn't go into N while it was off.

The big issue I have with DCT is no manual override (ie latch in center console) to engage N.

This is an glaring oversight by BMW. The funny thing is the latch is there but only accessible underneath the car after wrenching for a little bit.

So if your DCT F8x can't be started for some reason to be put in gear, the tow truck driver has to use a dolly or basically drag it onto the flatbed tow truck?

Correct (if you mean that the engine cannot be started to put the DCT in Neutral). This is probably the most significant design flaw of the F8X IMO. At least on the E9X, there was an easily accessible manual overide to disengage the parking pawl.

This sounds awful, can it damage the car? Calling BMW seems like a logical choice as I assume they would follow protocol to unlock park from underneath

Dollying the car won't damage it if done right, manual override won't damage it either but it's harder to get to.

BMW is only going to reach out to local provider. It is luck of the draw with them.

I got Lucky. Tow driver was super patient and had Dolly's to put under wheels and skates which he could use to position on flat bed.

On vacation right now driving a Mustang rental. I keep forgetting to put it in P every time I get out of the car. Pretty annoying that required additional step

That's what I'm saying. After we came back from ED last year with my wife's F80, I may or may not have killed the battery in my Camaro SS (that I had at the time) and/or had a freak out when it started rolling because I kept forgetting to put it in park.

NoMoreAudi · 08-07-2018, 06:42 PM

I don't know if someone mentioned this already but turning "off" the car while in gear is different than turning it off in neutral. It's only after the 2nd time you hit the "off" button will a neutral parked car go into "park."
