A shift solenoid is an electrically switched valve in the valve body. Manufacturers use these codes differently: Ford reports an open circuit with the base code and shorts separately, newer GM units have separate low/high codes, and the letter is not tied to a valve number (Saab's 9-5: A = valve S2). P0759 is an intermittent fault of solenoid B: the feedback briefly shows a fault and then recovers. No manufacturer document available to us uses this code: Ford watches its solenoid circuits continuously under the open and short codes, GM counts failures over a window (more than 43 of 50) under P0758. Brief dropouts make the module switch the solenoid off and enter limp mode until the next start.
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
- Limp mode or jolt at times, then normal again
- Warning lamp comes and goes
Most likely causes
- Loose contact or corrosion at the transmission connector
- Chafed harness, dependent on temperature or vibration
- Coil with heat-dependent winding fault
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
- It affects emissions.
What each character of P0759 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 7: Transmission
- 59: Specific fault in that system
Frequently asked questions
