Fluid leak from a seal, gasket, sump pan, cooler line or housing joint; Fluid level not correctly set after previous servicing or a fluid change; Leaking or damaged transmission cooler, cooler pipes or connections; Faulty fluid level sensor or damaged sensor wiring or connector, giving a false low reading; Fluid foaming or being displaced due to a wrong fluid type or a blocked breather; Internal wear causing pressure loss and a level reading that is wrongly interpreted as low.

What it means

P070F is the generic code for transmission fluid level too low. The transmission control unit has decided that the fluid level is below the minimum needed for safe operation. Depending on the vehicle, it reaches this conclusion from a level sensor, from a calculated level based on temperature and pressure, or from signs such as clutch slip and pressure loss.

Symptoms

Transmission warning light or low fluid message on the dashboard
Delayed or harsh engagement when selecting Drive or Reverse
Slipping, flaring or erratic gear changes
Whining or buzzing noise from the gearbox
Transmission going into limp mode or restricted gears
Red or brown fluid spots under the car

Possible causes

Fluid leak from a seal, gasket, sump pan, cooler line or housing jointlikely
Fluid level not correctly set after previous servicing or a fluid changelikely
Leaking or damaged transmission cooler, cooler pipes or connectionspossible
Faulty fluid level sensor or damaged sensor wiring or connector, giving a false low readingpossible
Fluid foaming or being displaced due to a wrong fluid type or a blocked breatherrare
Internal wear causing pressure loss and a level reading that is wrongly interpreted as lowrare

How to diagnose

Read all stored and pending codes and the freeze frame data, noting the fluid temperature and the conditions when the code set
Look under the car and around the gearbox for wet areas, drips and fluid trails, paying attention to the sump, driveshaft seals, bell housing and cooler pipes
Inspect the level sensor, its wiring and connector for damage, corrosion or chafing
Check the fluid level using the procedure specified for that model, as many sealed units need a set temperature and a level or fill plug check
Examine the fluid condition and smell for burning, contamination or metal particles
Pressure test or inspect the cooler circuit and lines for leaks or restrictions
Check the live level or temperature data against the actual measured level to see whether the sensor is at fault
Clear the code after the repair and road test, then recheck for the code returning

How to fix

Repair the source of the leak by renewing the faulty seal, gasket, sump or pipe
Top up or correct the fluid level with the specified fluid, following the model-specific procedure
Replace the leaking cooler or damaged cooler lines and connections
Repair the wiring or connector fault, or replace the level sensor if it has failed
Drain and refill with the correct fluid type if the wrong fluid has been used
Investigate internal faults through a specialist inspection if the level is correct but the problem persists

Can I keep driving?

High severity

Avoid driving until the fluid level has been checked and corrected, as low fluid can quickly cause overheating and expensive internal damage. If the car must be moved, keep the distance very short and drive gently.
