Finally got that weird 2012 Focus transmission shudder figured out
Had this customer come in with a 2012 Focus that had a nasty shudder between 2nd and 3rd gear, you know the one. He'd been to two other shops already. I spent a solid three hours just on the test drive and data logging, trying to catch it. The TCM adaptations were a mess, but the real kicker was the clutch actuator motor. Ford's TSB said to replace the whole thing, but I found the internal gear was just slightly worn. Cleaned it up, re-greased it with some Motorcraft XT-10, and did a full reset with the IDS. Drove it around Grand Rapids for like 20 miles after and it was smooth as butter. The look on the guy's face when he picked it up was worth the headache. Anyone else had luck fixing those actuators instead of just swapping them?
