P0700 on Saturn
Transmission Control System Malfunction
P0700 on Saturn vehicles indicates transmission control system malfunction. Au7o has documented this code across 1 Saturn model — most commonly on Vue. 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 Saturn range from $1,200 to $4,500, 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 Saturn by Model
Saturn Vue(1 issue)
- Vue VTi CVT Catastrophic Failure (2002-2005)2002-2005
Early Saturn Vue (2002-2005) was offered with the GM VT25 (VTi) continuously-variable transmission paired with the 2.2L Ecotec. The CVT was infamously unreliable — failure rates so high that GM extended warranty to 5 years/75,000 miles, and many independents won't touch them. Symptoms: belt slip noise, surge under acceleration, eventual no-drive.

What does P0700 mean on Saturn?▼
P0700 stands for "Transmission Control System Malfunction." 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. On Saturn specifically, this code is documented across 1 model.
What causes P0700 on Saturn vehicles?▼
Common causes on Saturn: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0700 on a Saturn?▼
Repair costs on Saturn range from $1,200 to $4,500, depending on the specific model and root cause.
