Replacing the computer won't fix anything if there is sensors triggering a fault If you punch in google the code number (called an obd2 code) it will tell you what sensors are being triggered usually it will turn out a misfire or o2 sensor it will always trigger if the sensor is faulty as for the shifting i couldn't tell you check the codes on google

SOURCE: Shift lever

It sounds like you may have a faulty shift interlock solenoid. It is under the center console. You can expose it and see if it is getting voltage when the vehicle is on and you foot is on the brake. If it is, replace the solenoid. If it isn't, you may have a faulty relay.

The end of the shift cable has broken, there is a plastic ring at the transmission end of the cable that breaks. You will need to have it towed to the mechanic.

Check your brake lights, if the system doesn't get a brake lights on signal it will not release park, it is called the park lock system.

Gear shift lever wont go into park and ignition switch won't turn all of the way off.

Sounds like you probably bent the "detent" in the transmission. You'd need to drop the trans pan and replace the linkage pertaining to this.

I have 96 chevy 1500 Z71 and the check eng light came on and is reading code P0758, P0753, P1886, and P1864 how can I fix this?

Check your plug-in connectors at the transmission and PCM. You can get free diagrams for the chassis at when you register your vehicle for free.

The following Codes are translated as 757-shift control solenoidA,753-shift control solenoidB,1886-shift timing solenoid,1864-Torque Converter Circuit.

I usually work on Ford type products, but looking at 4 codes can easily mean a common connector is corroded or loose. Look at the wiring Diagrams and you will probably see a connection that leads to all 4 of these parts.

GMC 1500 Auto, will not shift back into park?

Climb under your pickup and look where the cable connects to the side of the transmission and make sure there is not any mud around the cable or around the shift linkage hookup. If so clean it off and see if it will shift. We have found many of these with mud caked around the shift linkage or a lot of ice buildup and wont allow it to shift into park.
