Manual transmission Car parked on an inclined and car is not reversing

Question edited for clarity.
Question moved to sub category.

Parking on the incline would not cause this. Rack the shift lever all the way back and then forward into park. If that doesn't work, you need a mobile mechanic.

Are you on an incline? If so try rocking your vehicle forward and backward with others helping you. Your transmission may be bound. While the vehicle is rocking you should be able to shift the transmission into neutral.

When you have the E brake on the weight of the car is being held by the E brake. When you park the car in park and no E brake on, the weight of the car is loaded onto the drive train and gearbox.
The jerk (and clunk) is the preload being released from the drive train. Not good for your transmission and a bad way to leave a car parked.

Yes when you park on an incline you should always put your emergency brake on before shifting to park. Then whenyou are ready to move again put you car in gear before disengaging the emergency brake. this will remove the stress from the transmission.

Sounds to me like there is too much weight on the "park" gear. Have someone push the car forward a little bit, and do it gently, to release some of the pressure on the transmission, and it should shift from Park without a problem. I highly recommend if parking on an inclined driveway, or any hill, to use the parking brake if it is possible to do so. Good Luck

The parking mechanism in the transmission has a shaft which slides into a V shaped groove. This is designed to make it easier to put the car in park. The bad part is that it allows for a little movement. The best way to prevent this from happening again is to engage the parking brake when you put it in park, especially on an incline. This will prevent the rollback you experienced from happening again. Hope this helps.

You should always use your parking brake. Leave your foot on the brake,then apply the parking brake. If you don't,the only thing holding the car, is the mechanical parking pawl in the transmission,and yes, it could break or fail to hold the weight off the vehicle,and it would roll away,as well as damage the trans.

Sounds like you may have damaged the parking claw. Put the parking brake on when you park on an incline, You may need a new parking gear or gear claw.

alright the thing is u need to get glasses or something is wrong with ur transmission

loosen up the linkage at the transmission a little,click the linkage i click on the transmission(shift it manually to reverse),put the gear selector in the car in reverse,then tighten the linkage.see if that helps.
