Excessive Hydraulic Fluid Leakage
Table of contents
P1CCB JEEP Possible Causes
- Transmission Hydraulic System
- Transmission Mechanical Operation
- Faulty Transmission Controller Module (TCM)
How do I fix code P1CCB JEEP?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P1CCB JEEP code
The cost of diagnosing the P1CCB JEEP code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1CCB JEEP Description
This diagnostic checks if the leakage of the hydraulic circuit is below an acceptable amount. The purpose of this diagnostic is to protect the electro pump and to detect which hydraulic components are not working as expected. A small amount of leakage is normal due to the presence of electrovalves in the circuit. The Transmission Controller Module (TCM) uses leakage estimation models based upon fluid temperature, hydraulic pressure and electrovalves status. If the decrease in hydraulic pressure in a defined amount of time is greater than allowable, a leakage failure is detected. There are four leakage monitoring strategies used by this diagnostic: Circuit leakage with all electrovalves switched off. Odd clutch electrovalve leakage during regulation (switched on). Even clutch electrovalve leakage during regulation (switched on). Gate select electrovalve leakage during regulation (switched on).
