The gearbox control system is not performing as expected. It is a summary code — the specific cause is usually in the transmission module's own fault memory.
P0701 — also written PO7O1, P 0701, 0701 — is the OBD-II code for transmission control system range/performance. Same code, same fix: this page covers every spelling of it.
P0701 is a transmission fault code, typically costing £150–£1800 to put right in a UK garage.
What causes P0701?
- Low or burnt transmission fluid
- Failing solenoid pack
- Worn clutch packs in an automatic
- Speed sensor fault
How P0701 is fixed
- Read the transmission module directly, not just the engine ECU
- Check fluid level and condition at the correct temperature
- Fluid and filter service on a neglected box
- Replace the solenoid body if commanded and actual pressures disagree
P0701 repair cost in the UK
Most P0701 repairs land between £150–£1800 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Can you drive with P0701?
Drive gently and avoid motorways. A slipping automatic destroys itself quickly.
Urgency: high.
