2 Major Causes of Transmission Problems

Transmission problems can be such a pain, right? And the sad part is that you don’t even know what’s the issue.

Well, fear not, my friend, because we’re here to help! 

Because this segment will be all about Chevy Tahoe transmission problems. But that’s not all. You get the fixes as well.

So, enough talking, let’s get down to business!

Problem 1: Transmission Slipping

Transmission slipping is a common problem for chevy 2007 owners. Let’s look at why the slipping occurs.

Well, transmission fluid leaks and clutch problems are two of the main reasons. If you notice those symptoms, then you’re halfway done!

But if you do nothing in this situation, your car’s health will keep going bad. So, you obviously want to fix that issue, right? 

Check out our suggestions below.

Solution 

Transmission fluid leaks are easily fixable. In some cases, changing the transmission fluid can solve this issue. You can resolve this issue without needing any expert.

In some other cases, torque converter replacement is the only way. 

In cases of clutch or band problems, more time and effort (also tools) are required. Because without dismantling the transmission, you can’t repair those parts. So, try to be careful while dismantling the transmission parts.

Note: You should only attempt to fix this issue if you know how transmissions work. Otherwise, call an expert.

Problem 2: Sprag Plug Malfunction

Sprag is a unidirectional mechanical thing in the transmission that helps to change gears. Now, there are times when it gets busted and affects the transmission. 

In such cases, you will barely have any power in the vehicle. The milage left on your car won’t matter in such scenarios. Those broken parts will need some good inspection.

Now, let’s move on to look what’s the possible solution.

Solution 

As the sprag clutch is an internal component, it needs repair or replacement. If you want to DIY, you’ll need the necessary tools. Such as wheel bearing kits, screwdrivers, and Allen keys.

But in most cases, it’s best to not handle this technical stuff yourself. So, you can definitely contact the repair shop.

3 Most Common Transmission Trouble Codes & Their Solution

Unable to figure out your Tahoe’s transmission problems? Fear not, buddy! We know that frustration, and it’s not a good feeling. 

All types of vehicles face many technical issues. Even the mighty ford mustang has electrical problems!

That’s why learning about these transmission trouble codes will help you a lot. These will help you understand more about your car’s underlying issues.

Here are some of them for you:

P0706: Transmission Range Sensor Circuit Range/Performance

This trouble code is all about your range sensor. This DTC informs the owners by showing some common symptoms. These include Tahoe not shifting gears or very hard gear shifts, and trouble with ignition. 

Upon noticing such symptoms, you can identify that your transmission is in a bad shape.

What are the causes, you ask? 

Well, there are many. ECU problems, faulty wiring, and gear shift damage are just a few of them. In such cases, resetting the ECU will do you no good.

To get a proper diagnosis, the shift level needs to be in the reverse position. Then check if your engine starts. 

If it does, then unplug the transmission range sensor and check again. You will be sure of your problem if the engine starts.

Solution

You can change the whole transmission sensor if you think it’s completely damaged. Or you can only replace the wiring connectors upon confirming issues. Some older models can be fixed by adding a new shift linkage as well.

P0867: Transmission Fluid Pressure

Your transmission requires a certain level of fluids to function. A very low level of fluid presence can cause major issues with this component. 

Symptoms such as overheating, slipping, or dirty fluids are clear indicators of this DTC code. The code can be caused by a low level of fluids, leakage, or pump failure. A faulty pressure sensor is also responsible for this code.

Solution

This code is a bit tricky to fix. Because it needs thorough inspection for multiple parts of the car.

First and foremost, check the fluid level and change it & the filter if necessary. It’ll also be wise to check if you accidentally mixed transmission fluid oil too much.

If that does not help the issue, you may need some repair. Whether it’s leakage, wiring, or transmission pump, you have to find the issue. After finding the right cause, any one of those, or all of those, might need changes. 

Wait wait! Don’t forget the sensors. Fluid pressure & temperature can also be the culprit. If such cases arise, you might have to discard them and bring new ones.

P0814: Transmission Range Display Circuit

This is another very common yet problematic trouble code for chevy Tahoe transmissions. Range circuit problems can arise because of multiple factors. Faulty parts such as wires, connectors, or range sensors are the common ones. 

To be sure about the P0814 trouble code, check the wiring and connectors. If they check out fine, diagnose the sensor adjustment. After checking it thoroughly, the sensor will surely tell you its condition.

Solution 

You can fix the issue at home with simple tools when it’s about the sensor adjustment. 

When the issue can’t be resolved that way, it might need some further inspection. Upon confirming the issue, you may have to change the wiring or the sensor.
