Base code for the tenth on/off shift solenoid of an automatic transmission; which valve gets the letter J is decided by the manufacturer. No manufacturer documents this code publicly. Ford's gasoline OBD summary ends its shift solenoid list at SS E, the Genesis 8-speed bulletin stops at solenoid F, and GM and Toyota label their later valves as pressure control or clutch solenoids, so J stays unused in the known sources. CARB requires automatic transmission solenoids to be checked for functional response and circuit faults. A manufacturer reporting the fault type through a DTC suffix, as Toyota does for pressure control solenoid L, would store such faults under this base code instead of P08CD to P08D4. Expect harsh, missing or substitute-gear shifts.
Medium severity. Can I keep driving?Drive as little as possible and gently. If the transmission slips or stays in one gear, go slowly to a repair shop or call for a tow truck.
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed or missing shifts
- Transmission may hold a substitute gear
Most likely causes
- Shift solenoid J faulty (coil or valve)
- Contaminated or degraded transmission fluid restricting the valve
- Connector or harness fault between TCM and solenoid
- Transmission control module output fault
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: hard
- It can trigger limp mode.
- It affects emissions.
What each character of P08CC means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 8: Transmission
- CC: Specific fault in that system
Frequently asked questions
Can I keep driving with code P08CC?
Drive as little as possible and gently. If the transmission slips or stays in one gear, go slowly to a repair shop or call for a tow truck.
What causes code P08CC?
The most common causes are: shift solenoid J faulty (coil or valve); contaminated or degraded transmission fluid restricting the valve; connector or harness fault between TCM and solenoid.
