SOURCE: Mazda 92 B2200 Auto Pickup Will not shift from Park to Drive

I'm going to go out on a limb and guess that when you park the car, you pull up the hand (park) brake, shift from drive straight to park and then take your foot off the foot brake and the car moves slightly as it transfers the weight of the car from the foot brakes to, in your case, the transmission rather than the park brake.
Most people do.

When you do this, you're usually putting the weight of the car onto a small lever engaging notches on the drive shaft in the transmission, not the hand brake. The hand brake's designed to hold the car, the lever isn't, it's there just-in-case.
Take a look at http://auto.howstuffworks.com/automatic-transmission5.htm to see how flimsy this part is.

  • To fix the problem, you'll probably have to get this part in your transmission replaced. Fortunately it's the least significant part of the transmission so don't let them shaft you just because it's part of an automatic transmission.

  • To fix what caused the problem, you need your hand brake / park brake adjusted at the handle. You'll probably find that it adjusts at the other end (inside the rear wheel hubs) whenever you reverse.

For what it's worth, to avoid doing this damage to automatic transmissions whenever I'm stuck in one, I shift to Neutral then take my foot off the foot brake, then the car moves as it's weight shifts from the foot brake to the park brake which I often haven't pulled hard enough. Only when, in neutral, the car is stationary without the foot brake do I put it in park.
In Australia, it became illegal a couple of years ago to not be in the driver's seat when the engine's running. My understanding is that this was because, when the engine's running, sometimes older Automatic transmissions damaged in this way can shift out of Park. This is believed to be what has happened when you see unoccupied cars reversing in circles on "wildest police video" programs on TV. I also heard of some Borg-Warner automatic transmissions fitted to 80s model Ford Falcons (common in Australia), 70s model German saloons, which were particularly prone to Park failing to hold the car on a slope. I drove one for many years in a '75 BMW 528 in which some of it's other drivers developed the same habit.
Similarly, in my own car, I don't take my foot off the clutch until I've taken it off the brake without the car moving. Though the local Road & Traffic Authority regulation states "First gear if you're facing uphill, Reverse if you're facing downhill" I do the opposite because whatever damage might be done to panels will be cheaper than what would be done to the engine if the hand brake failed and it's not going to make much difference in slowing down a rolling car, especially with this one.

SOURCE: 1995 buick century stalls while driveing, will

It sounds like the motor stops receiving fuel at some point.This can be caused by either a clogged fuel filter or the fuel pump going bad.It's a tricky problem because in order to check the pump you need to have a fuel pressure guage hooked up to the fuel line and on top of that the problem would have to happen just at that time so you can see the pressure drop.Change filter first.Sediments in the filter may be floating into the outlet periodically stopping the fuel flow,the car shuts off and the sediments float away enabling the car to start again

The CVT should not make noise in park. So yes, I would get it checked out.

My 1980 450sl AC works good while in park, when I start driving it blows hot air could this be a vaccum problem?


Well, yes they did borrow the system from Chrysler and the main problem was with the main controller unit where you adjust the temp and has the controls. They were known to separate at the unit allowing vacuum to leak and to cause this problem as well. Typically when it is running, you should be able to put your fingers at the rear of the unit and find the vacuum leak that way.

If it runs when you pour gas into the intake then stops you have a bad fuel pump. In 1976 most used car orators. This being a German auto at that time... Maybe had the early fuel injection using the lamda (sp?) Mechanical system... If it does then you need a mechanic with experience on mechanical fuel injection.

Sounds like the ignition module on the fender.
You would need to know if you are missing spark to the plugs when it quits running. The carb would not run out of fuel then suddenly have fuel again.

starting up is way to slow
fuel pump pressure down
or EFI system fault , a faulty starter
if that all checks out
the 4 day to flat battery
parasitic draw from alternator ,

or ignition switch

you can buy quick release type battery terminals like used on marine boats

charge the battery up
and disconnect the battery terminals
until you want to drive the car again
when back home undo the battery terminal

My 1975 mercedes 450sl convertible will not start now since I fixed heater vents and hoses. It ran fine earlier today, but will not turn over at all now. Where under the hood are there any fusible links?
