yeah, um, that's not really an option on well adjusted ebrakes...
sometimes you can backup to get friction that will melt the ice. but forward is usually beyond the capabilities of the vehicle.

Seriously? There was so much snow in Ithaca this year and the temperatures were well below freezing. I've never had such an issue of the parking brake freezing. Heck even when I did some driving at 2am with the engine stone cold there weren't any problems.

What about cars that have a manual transmission? How are they supposed to park in the freezing cold???

I usually put it in first or reverse on a manual.
I wasn't saying it was an everyday thing, just in superfrigid temps, (waaaaay below zero) after driving through snow and such, the accumulated water can seize the ebrake. it happened to enough this winter that the announced it on the news in the south...

On all of my cars, before going into park, I apply brake, move gear selector to N then engage parking brake. Finally, I move gear selector to P. Going out of P, I move shifter to R or D then disengage parking brake.

To my beautiful wife (married 16 years today) the above formula is more complicated than string theory. I usually have to walk her through it every time. She doesn't understand why we can't be like everyone else and just rip the gear selector like its a one-armed-bandit.

I don't want any strain on the transmission.

This pretty much eliminates wear on the selector pauls and bushings.

(That being said, I could park my 83 Crown Vic on the steepest hill or driveway and it would slide into and out of gear like buttah). Miss that old easy chair of a car. However, 8 mpg was killing me.)

one of the guys I work with ALWAYS shuts down the car in D, rolls to a stop, and then puts it in Park after the vehicle is no longer moving.
hypermilers usually shutoff the engine prior to stopping as well... inertia don't burn any fuel!
I hate it when somebody uses park to stop the car from moving... ugh!

reminds me of the scene in The Terminator where sara conner slams it into park while reece and t1000 are fighting through the windshield...
NO WAY it would have stopped... or smoked the tires... it would've just gone BING BING BING BING over and over until they hit the wall...

I think i'm going to have more problems than the parking brake in super frigid temperatures

A former co-worker of mine was driving carpool and was driving his wife's brand new boat of an Olds, RWD with a big v8 while his Mercedes was in the shop. His Mercedes had the four speed column shift, and the Olds was an automatic. At the top of the onramp, he instinctively went for third, and park did engage for a brief second before it sheared the rear of the trans case. Sometimes they do engage-

As for the original question- Shift linkage bushings. This is a known issue, I got mine with "transmission problems" because of these bushings, I drove it for a couple months then parted it out. Use the parking brake, if your bellows seals on the cables are in good shape there won't be any freezing problems.

did the car stop, or did it just break the transmission and keep rolling?
it will blow my mind if an american automatic transmission parking pawl stopped a fast moving car!!!
