Why do i have to put my car in neutural to start it

grinds? A;T BOX GRINDS IS NEVER EVER GOOD.
PARK GRINDS ONLY IF ROLLING CAR DOING SO AND IS AN ILLEAGALL ACT THAT.

WILD GUESS A/T BOX SHIFT LINKAGE IS A WRECK
ALL SELECTIONS MUST WORK
THE SERVICE MANUAL TOLD YOU TO TEST THEM ALL
PRNDL
PARK CAR DOES NOT ROLL ,HAND PUSHED
NEUTURAL CAR ROLLS PUSHED BRAKES OFF
LOW CAUSE 1ST GEAR TO MOVE CAR
rEV MAKES CAR GO REVERSE
DRIVE STARTS IN 1ST THEN 2,3,4, ETC.
ALL MUST WORK IF NOT, ALL, THE LINKAGE IS A WRECK.

Simple the park start switch isn't functioning. If I remember correctly that is located in the center shifter console. Try pressing the shifter further toward the park setting. If it works now you may wish to adjust the shifter cable in the console. Otherwise take an allen wrench and loosen the retainer screw on the shifter and pull it off. Now remove the shroud to the console. With the console cover off you may be able to see the problem, but if everything stilll looks perfect and it still doesn't work replace the switch.

You have air in the hydraulic clutch system.

My 99 accord was doing the same thing and after alot of research I found out it was a bad igition module. Fairly cheap 200$ part but took care of the issue.

You do have drive and reverse,if you have park and neutral.It just the transmission cant transfer that power a new or rebuilt is the solution

Hi, welcome to FixYa.com my name is Shawn and I will be answering your question.

Sounds like you are looking for the shift interlock solenoid located on the steering column. If the car won't shift out of park first check your brake lights and make sure they work. This is normally caused by a faulty brake light switch located on the brake pedal or a broken wiring connector to the brake switch. You can bypass this by putting the car in neutral then starting it.

I hope my assistance helped you and resolved your concern, if you need further assistance please as

If this is the case the torque convertor clutch solenoid will need replacement. You can buy some time by disconnecting it. The transmission will shift fine but the check engine light will stay on.

The switch on the transmission that tells the computer that it is in park is bad. It could be that or you need a mechanic to reset the code in the computer. Your best bet is to have it looked over, but it only could be one of those two things. Hope this helps.

Not a good idea. It is there for a reason.
