What does this fault code mean?

The fault code concerns clutch C3 in the gearbox, which is controlled by line pressure solenoid SL3. The control module has detected that clutch C3 or brake B2 has not engaged correctly. The fault is general and does not say more precisely what type of fault it is.

Possible causes

Clutch C3 or the band brake is damaged
Contact resistance, oxidation or a loose joint at the plug of line pressure solenoid SL3
Open circuit, short-circuit to ground or short-circuit to voltage on the cable to line pressure solenoid SL3
Line pressure solenoid SL3 is damaged
Internal fault in the transmission's control system or in the transmission control module (TCM)
Mechanical fault in the gearbox

What you can do
