install transmission shifter assembly
It is inside the shifter.
either the shifter linkage is not fully engaged in park or the park lock is broke inside the transmission
go ask a mechanic
A Taurus auto that will not shift from the column shifter is usually due to a transmission issue. Transmission's are an expensive fix. Shop around before committing to one mechanic.
If you cannot move the shifter out of the park position then you have a problem with the shifter cable or the brake safety lock. If you can move the shifter to the drive position, and it doesnt go in gear then you are a few quarts low on transmission fluid
The shifter cable connects the shifter to the transmission.
Check to see if you have a bad stop light fuse. ON my Honda a blown stop light fuse shuts down power to the transmission lock out circuit. Likely a simple fix? Good luck
Key is designed to not come out unless the transmission is in the park position. If the shifter is in park but the transmission is not, then the linkage (which hooks the shifter to the transmission) has somehow come out of adjusment. It will need to be adjusted - I would suggest having this done by a professional.
Check to make sure that the shift linkage is adjusted properly. If not, the linkage may not be able to move the gears inside the transmission enough to properly engage. I have a Daytona that has a procedure to lock the transmission in a known position, the shift cables are loosened at the shifter, and two rods are placed in the shifter to lock it in a corresponding known position. Then the cables connecting the two are tightened down, the 'locks' are removed, and everything is good to go. Check to see if the linkage on the transmission or in the gear shifter inside the car is bent. Check to see if something is interfering with the shift linkage. Could be a hose or something in the way. You may have to open the transmission if the remedies above didn't fix it. Something may be bent inside the transmission preventing the gears from engaging properly.
This should be really simple, if you've already removed all of the bolts which hold the shifter in including the one behind the shifter hole in the trans, the shifter should slide right down into the transmission (provided the transmission was in neutral when you pulled the shifter)
sounds like you need to adjust your shifter linkage
To fix a shifter in a Pontiac Bonneville, start by inspecting the shifter linkage and cables for any signs of wear or disconnection. If the shifter feels loose or doesn't engage properly, check the bushings and adjust or replace them as necessary. Additionally, ensure that the transmission fluid is at the correct level, as low fluid can affect shifting. If problems persist, consider consulting a professional mechanic for further diagnosis.
