5 Troubleshooting Tips for When Your Chevy Truck Won’t Go Into Park

The most likely cause for a Chevy truck not going into park is an issue with the shift linkage.

Chevy Truck Wont Go Into Park

If your Chevy Truck won’t go into Park, there may be a problem with a malfunctioning park/neutral switch or shift control cable. The primary cause of this condition is generally due to wear in the cable, which could be easily replaced. However, it is also possible that there may be a problem with the transmission or other component, linking them together. In this case, it will be necessary to have a trained automotive technician diagnose and repair the issue and return your truck to proper working order.

Identifying the Problem

When a Chevy truck won’t go into park, it’s important to identify the cause of the issue. Reasons for this problem can range from a faulty ignition or shifter lock cylinder to worn-out linkages and cables. Symptoms of this issue can include difficulty shifting into and out of park, or the vehicle rolling when placed in park. Knowing what the problem is will help determine how to fix it.

Modifying Fluid Levels

Modifying fluid levels is one way to ensure that your Chevy truck shifts properly into park. This includes checking and making sure that the oil level is correct, as well as using the correct type of fluid in the transmission system, such as Dexron VI or Mercon V.

Checking External Components & Wiring Issues

It’s also important to check external components and wiring issues when troubleshooting why a Chevy truck won’t go into park. This includes inspecting all linkages and cables for any signs of wear or damage, as well as checking all electrical connectors for any corrosion.

Faulty Parts Replacement Options

If any of these components are found to be faulty, then replacement parts may be necessary. Common parts that may need replacing include an ignition or shifter lock cylinder, as well as a park pawl and gear shift cable assembly.

Diagnosing the Problem with OBD II Codes & Scan Tool Results

When attempting to diagnose why a Chevy truck won’t go into park, OBD II codes can provide helpful insight into what may be causing the issue. Using a scan tool can also help retrieve vehicle component status and other useful information regarding why the problem is occurring. A checklist of OBD codes can be used to help guide diagnosis processes in order to accurately identify what needs repairs or replacing in order to resolve this issue with your Chevy truck.

Identifying the Problem

When a Chevy truck won’t go into park, it can be extremely frustrating and potentially dangerous. To determine the cause of the issue, it is important to first identify what is causing the problem. There are several potential causes for a Chevy truck not going into park, including faulty fluids, gear selector position sensors, servo systems, actuator systems, and park position switches.


The most common reason for a Chevy truck not going into park is a fluid leak or low fluid level. The transmission fluid needs to be at the proper level in order for the vehicle to shift correctly. If there is a leak or if the fluid levels are too low, this can cause a shift lock in which the vehicle will not go into park. Another common cause could be an issue with the gear selector position sensor. This sensor detects the position of the gear selector and sends signals to other components in order for them to function properly. If this sensor is not working correctly, it can prevent the vehicle from going into park.


A few signs that may indicate that your Chevy truck is having trouble shifting into park include difficulty shifting out of drive or reverse and an inability to move forward or backward while trying to shift into park. Other symptoms may include loud noises coming from underneath the hood when shifting from drive to reverse and vice versa as well as jerking when attempting to put it into park.

Modifying Fluid Levels

If you suspect that your transmission fluid levels are causing your Chevy truck not to go into park, you should start by checking your oil level and fluid type. If you find that either one is low or incorrect type of oil is being used then you should immediately replace it with correct grade oil or transmission fluid as recommended by your cars manufacturer manual. This should help resolve any issues with shifting gears while driving as well as help get your vehicle back in gear quicker when trying to put it in park mode.

Oil Level

Checking your oil level regularly is essential for keeping your vehicle running smoothly and efficiently throughout its lifetime. Low levels can cause problems such as poor acceleration due to lack of lubrication between engine components; increased fuel consumption; increased emissions; poor shifting performance; and longer warm up time after starting up cold engines due to insufficient lubrication on start up . You should also check for any leaks or contamination which can lead to further issues if left unchecked.

Fluid Type

It is important that you use only recommended fluids for your vehicles make and model when refilling fluids such as engine oil or transmission fluid . Using an incorrect type of oil can lead to damage such as sludge build up leading clogged filters which will reduce performance and efficiency over time . Additionally , using an incorrect type of transmission fluid can cause shifts between gears feel harder than usual , which could lead further issues down the road if left unchecked .
