What is the transmission failure of the Jeep Cherokee?

[DelJuniper]

The Jeep Cherokee is prone to transmission failures, with the dashboard displaying a "Service Transmission" warning. When this issue occurs, the vehicle typically enters a self-protection mode known as "limp mode" or "lock-up," resulting in sluggish acceleration and inability to gain speed. This serves as a reminder for the owner to seek vehicle maintenance, as the car's computer system prevents further driving and mandates a transmission inspection. Detailed information is as follows: 1. Transmission disassembly: This involves the valve body, which is particularly susceptible to failure in this transmission model. The valve body contains electronic components that, due to prolonged exposure to high-temperature transmission fluid, often develop circuit issues (commonly referred to as wiring harness problems). The wiring harness in this transmission can be replaced individually. 2. Overheated clutch plates: There are four sets of clutch plates in total, two of which may overheat to the point of disintegration upon touch. Overheated clutch plates must be replaced, as failure to do so will impair clutch braking and gear shifting. This is why aggressive acceleration should be avoided in limp mode, as it can cause severe damage to the transmission.
