3. Step-by-Step DIY Repair Guide for Subaru Crosstrek
Ensure fluid is at the hot full mark and not burnt or black. on the Subaru Crosstrek equipped with 2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP).
Monitor TCC Commanded vs TCC Slip RPM on scanner at 60 mph. With lockup engaged, slip RPM should be under 20 RPM. If slip remains 200–600 RPM, clutch is not locking. on the Subaru Crosstrek equipped with 2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP).
Replace transmission fluid and filter. In many cases, fresh fluid with new friction modifiers frees a sticky TCC solenoid valve. on the Subaru Crosstrek equipped with 2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP).
Drop transmission oil pan, remove valve body cover, test solenoid resistance (typically 10–20 ohms), and replace faulty TCC solenoid. on the Subaru Crosstrek equipped with 2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP).
Clear DTCs and test drive on highway to confirm lockup engagement. on the Subaru Crosstrek equipped with 2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP).

4. Subaru Crosstrek P0741 FAQs
What causes code P0741 to trigger on a Subaru Crosstrek?
On the Subaru Crosstrek (2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP)), P0741 is most frequently caused by Faulty TCC lockup solenoid or valve body channel stuck with varnish or Burnt or contaminated automatic transmission fluid.
Where is the OBD-II port located on my Subaru Crosstrek?
On the Subaru Crosstrek, the 16-pin DLC diagnostic connector is located Under driver side steering column. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Subaru Crosstrek with code P0741?
Yes, for local driving. Highway fuel economy will decrease by 2–4 MPG as the torque converter cannot achieve 100% mechanical lockup. Given that P0741 carries a Medium severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
