P0700 on Saab
Transmission Control System Malfunction
P0700 on Saab vehicles indicates transmission control system malfunction. Au7o has documented this code across 2 Saab models — most commonly on 9-3, 9-5. P0700 is a general code indicating the transmission control module (TCM) has detected a fault somewhere in the transmission control system and has requested the check engine light be turned on. By itself it doesn't pinpoint the problem — it's an 'umbrella' code that tells you to look for additional, more specific transmission codes stored alongside it. The actual fault could be electrical, a sensor, a solenoid, or an internal transmission issue. You may notice harsh or delayed shifts, slipping, or the transmission going into a protective 'limp' mode. Typical repair costs on Saab range from $120 to $3,000, depending on the specific model and root cause.
Common Causes of P0700
- •Stored companion transmission codes pointing to the real fault
- •Faulty shift solenoid or pressure control solenoid
- •Low, dirty, or degraded transmission fluid
- •Faulty transmission speed or input/output sensor
- •Wiring, connector, or ground problems at the transmission
- •Failing transmission control module (TCM)
- •Internal transmission mechanical wear or clutch problems
- •Valve body fault or sticking valves
P0700 on Saab by Model
Saab 9-3(1 issue)
- 9-3 Sentronic (Aisin AF33-5) 5-Speed Auto Failure2003-2011
Second-gen 9-3 (2003-2011) Sentronic 5-speed automatic is the Aisin AF33-5. Develops harsh shifts, slipping, then total failure typically by 100,000-150,000 miles. Saab's "lifetime fill" claim was the prime contributor. Failure mode includes valve body wear and torque-converter shudder.
Saab 9-5(1 issue)
- 5-Speed Automatic Transmission Limp Mode / Valve Body Faults2002-2009
The automatic 9-5 can drop into limp mode (locked in a single gear until restart) and develop slipping or harsh shifts. Early versions of the 5-speed automatic introduced around 2002 had valve-body and software issues; common triggers include the torque-converter lock-up solenoid, speed-sensor faults, and degraded fluid. In limp mode the car launches in a high gear with an unlocked converter and bangs into gear on upshifts.
