If it's automatic, then possibly low on fluid, trans solenoid problem, dirty trans filter. If manual, possibly clutch, throwout bearing, haydraulics etc.
brake switch gone bad car will not shift out of park if brake goes bad
That would be a car with a standard shift 6 speed transmission.
No, but why would you?
Because that's what they want.
i think it would because it would make the gear shift better and lube them and help it
It matters if you have atuomatic or manual transmission. In an automatic car the gears shift on it's own. In an manual car you shift buy pushing the clutch and then shift from 1st gear to 2 gear.
sounds like clutch needs adjustment or time to replace it
Failing transmission
If your car is an automatic (not a stick shift) then the car will automatically shift down as you ease off the gas petal. If it doesn't down shift then you need to have the vehicle checked out to see what is wrong.
There are many parts involved and lots of labor hours. Having a standard shift car like yours for parts would be best if you want to give it a go. It would be easier and cheaper to just buy a good standard shift car of your choice and drive it.
How would you know about my car? Get literate! The friendly answer is worn engine mounts or to high idle speed.
It means that you do not have stick shift in your car, your car shifts gears for you, you don't have to do it, so basically if you don't have a stick shift car you have an automatic transmission car.
