If your brakes fail what is the first thing to do?
If your brakes fail, it is an emergency situation that requires quick and decisive actions. Follow these procedures: Shift to a lower gear to decrease the speed of the vehicle. Pump the brake pedal in an attempt to restore pressure to the brake system. If pressure is restored, stop pumping. If this technique does not restore your brakes, use the parking brake to aid in slowing and stopping the vehicle. Be careful; applying the parking brake too abruptly may lock the rear wheels and put the vehicle in a skid. To prevent this, use your thumb on the release button, or pull the brake release as you alternately apply and release pressure using the parking brake. If necessary, steer towards something soft (sand or pea gravel) or into a clear area off the roadway. If a collision is unavoidable, steer to sideswipe rather than colliding head-on; this will reduce the force of impact force.

Asked in Auto Parts and Repairs, Hyundai Sonata
Does the 2006 Hyundai Sonata have a known problem with the shift lock release?
Yes; to keep things from locking up, when you park the car and remove the keys, make sure the tires are straight and not turned one way or the other. If it has locked, apply pressure to the locked steering wheel either clockwise or counter clockwise at the same time as you also apply slight pressure to the ignition key.
Can you shift the gears in automatic transmission cars even when the car is not running?
You can move the lever. But without pressure from the transmission fluid pump run by the engine, the only thing that will happen is the park latch locking and unlocking the drive shaft. Incidentally, this is why you don't stop the engine when trying to stop without brakes. Without pressure from the pump, the transmission shifts into neutral, no matter where the gearshift lever is. Instead shift down one gear at a time, letting engine braking slow the car. Then turn uphill and shift into park when the car comes to rest.

Th350 shifts to second when shifter still in first?
Unless you have a manual valve body (i.e. typically a race only application) the tranny will shift to a higher gear ratio when it senses that a shift is necessary. This is the same reason that you may be able to manually shift from second to third with the shifter but the tranny might stay in second until it senses that it needs to shift. Your auto tranny is governed by pressure. There is main line pressure which is what the pump puts out and is used to apply clutches or bands. It is also converted to throttling pressure and governor pressure. Throttling pressure and gov. pressure oppose ea. other. The kick down linkage controls a valve which allows fluid pressure to act upon a plunger. The gov. which is a spring loaded flywheel with weights controls a valve that allows fluid pressure to act upon the other side of plunger that throttling pressure is acting upon. Under the right conditions one may oppose the other. If your gear selector is in first and you drive the car at a high speed (for the gear you are in) eventually gov. pressure will overcome throttle pressure and your tranny will shift. The placement of the shifter is just "telling" the tranny that 1st gear is your preference by directing fluid pressure to the first gear clutch pack to which there is a bypass that will direct the fluid pressure to the second gear pack when a shift is necessary. If you feel that the tranny is up shifting too early (i.e. at a lower engine speed with a high load) then you may need to have the tranny looked at for repair.
