It sometimes won't start unless I jam the shift into park, now won't start at all! How do I fix this???

there are two bolts underneath the steering column where it meets the dash. Make sure these are tight

Gear shift is not totally in the park position - had the same problem with a 2011 Acura TL - a rubber band kept the gear shift lever from totally seating in the park position.

Sounde like the shift linkage cable from the console to the steering column needs adjustment. Robert

Hie it got stretched along the way to the transmission box check to make it free the selector cable

Sometimes the steering wheel has a lock mode when the car is off, and then gets stuck there. Try wiggling the wheel after you start the car.

Gday mate,geoff here, now on your shifter if column shift there is an adjustment where it goes down the box from the steering column under the hood and if stick shift should be just under the console, alternitiveley the rubber grommets on the linkage are worn and need replacement, some fuel hose will surfice here if the grommets are unavailable at the parts counter, hope this helped, geoff.

It sounds like the shift linkage needs to be adjusted, it doesn't sound like it's all the way in park.

these have a safety system so the shifter won`t go into any gear unless the brake is pushed(indicating someone sitting in the drivers seat),if the brake lights aren`t working this indicates that the fuse that operates the shift lock solenoid and brake lights is not working and needs replacing.check the fuses and replace the fuse and things will probably return to normal.

Can't shift out of park because I've parked on a slight hill and my car has backed up slightly jaming the parking pawl in the automatic transmission after I have shifted into park but before I have set the parking brake. This is a complaint that Ford owners have had for years. Try this proceedure to see if this solves you problem and best of all it's Free. 1st when you park develop the habit of; while still having the foot brake down apply the park brake firmly first and then shift into park and then release the foot brake. Remember it is important to apply park brake with enough force to prevent the vehicle from rolling. What happens is in the rear of an automatic transmission there is a coarse gear that has a lever that engages this larger gear and when you shift into park range this lever goes into one of the spaces in the larger gear and stops the car from rolling. If the car starts to roll it can Jam the lever against the gear and make it difficult to shift out of park. By using the procedure I've outlined it prevents the lever OR Pawl from being jambed into the larger park gear. Try to make this a habit and you shouldn't have anymore problems.

try replacing the neutral safety switch
