It can cause the fluid to break down at a high rate. It is recommended to use the vehicle's instructed fluid level in order to handle this issue.
5. Over temperature Indicators:
The message sometimes shows the issue of transmission over temperature. For example, the pop-up message indicates the issue with the transmission temperature sensor circuit.
When the transmission temperature measurement and neutral safety switch function are on the same wire, it can give false warning. The false message can also be due to a faulty radiator.
6. Heavy Use:
The towing and hauling capacity associated with the Jeep Grand Cherokee makes the transmission work harder. In addition, it leads to the production of more stress that generates extra heat.
7. Clogged Radiator:
A clogged radiator in a vehicle is also a major cause of transmission over-temperature problems in the Jeep Grand Cherokee vehicle.
The radiator in the vehicle cools the transmission fluid. If the radiator is not working properly, it can cause the fluid to overheat, causing problems of transmission slipping or attaining the neutral or reverse phase.
8. A Fault in the Thermostat:
A faulty thermostat is responsible for creating the transmission over-temperature problem. The thermostat is responsible for regulating the temperature of the transmission fluid.
If the thermostat does not work properly, it can cause the same issue of fluid overheating, leading to the problems of slipping of transmission to the reverse or neutral.
