Jeep Selec Trac Problems

1. Transmission

The first problem I had with my Jeep was that it shifted badly. I went to the Jeep dealership hoping they could fix that. When I took it to them, they said the problem had to do with a transmission solenoid, which only costs $125 if you want to replace it. 

2. Selec Trac Shift Cable

I took my Jeep to the dealership again because I couldn’t shift into “D” or reverse without holding down the gas pedal. The mechanic at the Jeep dealership told me about a problem with the shift cable for my Selec Trac transmission and that I will have to replace it.

The cost of this was $215, so instead of paying that much money, I decided to change it myself under warranty and bought a new one myself.

3. Selec Trac Front Differential

The mechanic at the dealership told me that my Selec Trac front differential is going bad and has to be replaced. I went ahead and bought a new one for about $275, but then decided to change it for myself after 12 years. They don’t have a “diff” in their name, but it is pretty much the same thing.

4. Selec Trac Transfer Case

I heard my Jeep not shifting properly, so I went to the Jeep dealership to get it fixed. They said there is a problem with the transfer case and that it had to be replaced. This cost $555 and I decided against getting it done myself.

5. Selec Trac Block

They went ahead and replaced my Selec Trac block as well, which cost $445. I decided not to get it done myself because they said that it was a very difficult job to do and that they would be using different parts on the front where the trans transfer case is so they will have to remove a lot of parts from the engine on my Jeep.

This is almost impossible unless you have like an automatic transmission, but even then it would be tough.

6. Selec Trac Shifter Linkage

Finally, I had a problem with my Jeep that was not mechanical. I got in for a few minutes and then drove off to go do something else. When I came back, my engine suddenly shut off. The mechanic took it out and told me that the transmission was completely damaged and that he wouldn’t be able to repair it because of how bad the damage was.

How Does Jeep Selec-Trac Work?

Jeep Selec-Trac is a full-time four-wheel drive system that was introduced in the 1980s. It is an electronic shift-on-the-fly system that allows the driver to switch between two and four-wheel drive while driving. The Selec-Trac system uses a sensor to detect when one of the driven wheels is slipping and sends power to the other wheels to prevent loss of traction.

The system has three different modes: 2WD, 4WD Auto, and 4WD Lock. 2WD Mode: In this mode, power is only sent to the rear wheels unless a slip is detected. This mode is best for dry pavement conditions.

4WD Auto Mode: Power is initially sent only to the rear wheels but is automatically redirected to all four wheels when slip is detected. This mode can be used on wet or icy roads. 4WD Lock Mode: Power is evenly distributed between all four wheels at all times.

This mode should only be used on very slippery surfaces such as mud or sand since it can cause tire wear if used on dry pavement.

What Jeep Has Selec-Trac System?

The Jeep Grand Cherokee has a Selec-Trac system that allows the driver to choose between two or four-wheel drive. This system is designed to give the driver more control over the vehicle, and it can be useful in different types of terrain. The Selec-Trac system is easy to use and it can be switched on and off with a simple push of a button.

How Do You Use a Jeep Grand Cherokee Selec-Trac?

Assuming you are referring to the Selec-Trac II 4WD system found in many Jeep Grand Cherokees: The Selec-Trac II 4WD system is an automatically engaging four-wheel drive system. There is no need to manually engage the front axle, as the system will do it for you when needed.

The Selec-Trac II 4WD system has three different modes that can be selected by the driver: 2WD Mode: In this mode, only the rear wheels of the Jeep are driven. This is the most fuel-efficient mode and should be used whenever possible.

It is also useful for towing purposes, as it puts less stress on the drivetrain. 4WD Auto Mode: This is the default setting for most driving conditions. The Jeep will remain in 2WD mode until sensors detect slippage from the rear wheels.

At that point, power will be distributed to all four wheels automatically. This provides increased traction and stability without sacrificing fuel economy. 4WD Low Mode: This mode should only be used when conditions are extremely slippery, such as on ice or in deep mud/snow.

In this mode, power is directed solely to the rear wheels until sensors detect slippage. At that point, power is then sent equally to all four wheels. This provides maximum traction but also decreases fuel economy significantly.

What is Wrangler Selec-Trac?

Wrangler Selec-Trac is a full-time four-wheel drive system found on some Jeep Wrangler models. It allows the driver to select between two-wheel drive and four-wheel drive, depending on road conditions. Four-wheel drive is generally used for off-road driving or when extra traction is needed, such as in snow or mud.

Two-wheel drive is typically used on paved roads. The Selec-Trac system automatically switches between the two modes, based on sensors that monitor wheel speed, throttle position, and vehicle momentum. The advantage of having a full-time four-wheel drive system is that it’s always ready to switch to a four-wheel mode when necessary.

This can be helpful if you find yourself in an unexpectedly slippery situation while driving on paved roads. If you’re interested in purchasing a Jeep Wrangler with Selec-Trac, be aware that it’s only available on certain trim levels and models.

It’s also important to note that this system doesn’t necessarily provide more power or performance – it simply helps with traction control.

What is the difference between Quadra Trac and Selec Trac?

Quadra Trac is the first four-wheel drive system in use by Jeep. Quadra Trac I was used from 1977 until 1988. It has a 4:1 low range and uses a part-time system with a two-speed transfer case.

Quadra Trac II was used from 1989 until 1994. It has the same basic setup as Quadra Trac I but adds a third speed (direct drive) to the transfer case and uses electronic sensors. This new system was only used on the Jeep Wagoneer and Grand Wagoneer.

Selec Trac is a newer four-wheel-drive drive system. It consists of a front part-time transfer case, a rear part-time transfer case, and an electronically controlled Dana 60 high and low-range differential.

The Quadra Trac uses an electro-actuated clutch pack that sits between the transmission and the front differential. This clutch pack can engage or disengage the front axles for better traction during wheel spin.

What is different about the Selec Trac drive system?

The Selec Trac drive system has a full-time (100%) transfer case and two different front axle gear ratios that can be selected either using an electronic shift lever or using a switch in the cabin of the vehicle. The front axle can be locked into low gear or neutral for off-road and low traction situations.

The Selec Trac uses a chain and sprocket system to connect the front axle to the transfer case. The front differential is located in the center of the transmission, so removing the transfer case from your vehicle will not affect your ability to drive.

The front differential is also placed at a lower angle than on previous Quadra Trac systems, which increases ground clearance.

How hard is it to change out an engine?

It really is not as hard as one would think. You just need to make sure you have the right tools and know how to take things apart. There are also lots of online videos that can help you along the way when you need them. 

It may seem overwhelming at first, but in reality, it is not too difficult to change out an engine if you have a diagnostic scanner and a YouTube account.

What does snow mode do in Jeep Grand Cherokee?

In snow mode, your Jeep Grand Cherokee will use the low-range transfer case and 4WD system to prevent it from spinning when you have high traction on the road. This will allow you to drive straight ahead in both low (2-wheel drive) or high (4-wheel drive) gears.

This is a good feature to have when driving in snowy conditions. In deep snow, however, it is still necessary to drive in 2-wheel drive or low range for best traction.

How do you put a manual transmission in a Jeep Grand Cherokee?

There are a few different methods of changing out the transmission on your vehicle. They include changing out the entire transmission and replacing only the transfer case and/or rear end.

This might be necessary if your transmission is worn out and needs to be replaced so that you can continue to use your vehicle while having more than one gear available.

This transfer case is the easier of the two to get in and out of. You can also see on my Jeep’s page that it has a rusted-out differential cover, but this does not affect the transfer case at all.

There are a few different ways you could do this swap by yourself, but it is extremely difficult and I would only recommend it if you have a lot of experience with vehicles and mechanical work. If you are willing to do some work, however, and have about an hour or so of time to spare, then I would recommend that you do this transfer case swap yourself.

If you go the easy way this is a fairly simple swap. The only issue one might run into is finding the gearbox you need for your vehicle. It’s relatively rare that someone would need this swap done because it is fairly easy to do yourself if you have mechanical experience.

What are the differences between a Chrysler and Jeep transfer case?

The gear ratios of a Chrysler and Jeep transfer case are very different, however, they both use the same size chain. The main difference is that they have different gear ratios so that they can both be used in front-wheel drive or rear-wheel drive vehicles. As you can see here to make this work a counter gear was added to the Chrysler Case. 

This change allows for more options and possible differentials that would have previously been incompatible with the Jeep transfer cases.
