Car mostly sat for 10 mos. Afterwards, difficulty going from neutral to 1st at a stop and sometimes difficulty pulling from gear while driving and clutched in. Finally confirmation the clutch wasn’t engaging was up on a lift, pushing into 1st clutched in, and the wheels spun.
I’ve since replaced everything so I can’t say this is the exact cause. Symptoms match and the clutch disc movement wasn’t super slippery. I’ll report back as soon as it gets on the pavement.
