you keep your ride smooth and worry-free.

What Is the Jeep Cherokee Transmission 722 6 Code P0700?

Before jumping into fixes, let’s clarify what this code means. The P0700 is a diagnostic

trouble code (DTC) that signals a problem with the transmission control system.

Specifically, it indicates that the transmission control module has detected an internal

fault and has set this generic code to alert the vehicle’s onboard computer.

The “722.6” refers to the transmission model itself—a 5-speed automatic transmission

originally developed by Mercedes-Benz and later used in various Jeep Cherokee models.

This transmission is known for its mechanical robustness but can be susceptible to certain

electronic and hydraulic issues as it ages.

When the P0700 code pops up, it’s often accompanied by other transmission-related

codes that the TCM records internally. These secondary codes provide more detail on the

specific fault, but P0700 serves as the initial “check engine” warning to signal

transmission control problems.

Why Does the P0700 Code Appear on Jeep Cherokee with 722.6

Transmission?

The P0700 code essentially means “transmission control system malfunction,” but the

root causes can vary widely. Some of the most common reasons this code appears on

Jeep Cherokees equipped with the 722.6 transmission include:

Faulty Transmission Control Module (TCM): The brain of the transmission, if

1.

malfunctioning, can trigger error codes.

Wiring and Connector Issues: Damaged or corroded wiring harnesses or

2.

connectors can disrupt communication between the TCM and transmission.

Transmission Fluid Problems: Low fluid levels, old or contaminated fluid, or leaks

3.

can affect hydraulic pressure and transmission performance.

Mechanical Transmission Issues: Problems like worn clutch packs, solenoid

4.

failures, or valve body malfunctions can cause the TCM to throw a P0700 code.

Sensor Failures: Speed sensors or input/output sensors that feed data to the TCM

5.

might malfunction, triggering errors.

Understanding these causes is crucial because the P0700 code itself doesn’t specify the

exact problem. It’s a gateway code that means additional diagnostic work is necessary.

Diagnosing Jeep Cherokee Transmission 722 6 Code P0700

Diagnosing issues related to the P0700 code on a Jeep Cherokee with the 722.6

transmission requires a systematic approach. Simply clearing the code without proper

diagnosis will likely result in the code returning, as the underlying problem remains

unresolved.

Step 1: Scan for Additional Transmission Codes

The first step is always to use a reliable OBD-II scanner capable of reading transmission-

specific trouble codes. Since P0700 is a generic alert, your scanner should reveal

secondary codes stored in the TCM that give more precise information, such as:

P0730 – Incorrect gear ratio

1.

P0740 – Torque converter clutch circuit malfunction

2.

P0750 – Shift solenoid malfunction

3.

P0715 – Input/Turbine speed sensor malfunction

4.

These codes help narrow down whether the problem is electrical, hydraulic, or

mechanical.

Step 2: Inspect Transmission Fluid

Since the 722.6 transmission depends heavily on clean, properly pressurized fluid,

checking the fluid level and condition is critical. Low fluid can cause erratic shifting and

trigger codes. Fluid that is dark, burnt-smelling, or full of debris indicates the need for a

flush or replacement.

Step 3: Examine Wiring and Connectors

Because communication between the transmission and control modules happens over

wiring harnesses, inspecting these for frays, corrosion, or loose connections is vital. Areas

near the transmission pan or under the vehicle are prone to damage from road debris or

heat.

Step 4: Test Transmission Components

If no electrical or fluid issues are apparent, mechanical components like solenoids,

sensors, or the valve body might be the cause. Many Jeep Cherokee owners report

solenoid pack failures in the 722.6 transmissions, which can cause shifting problems and

trigger the P0700 code.
