I'm a 70 year old DIY that bought a then new 2005 TC for my son. Fast forward 15 years later I traded my Camry with his Scion. 3 weeks ago and 317,000+ miles the clutch started acting up. I couldn't get in gear less I turned off the car. Even when I start it with it in 1st gear and fully depressed the clutch, I can feel the car ever so slightly moving forward. Only way it can do that is if the pressure plate is not pulled back all the way. I changed the Primary and secondary slave cylinder with a 1/4 inch push rod, but still doing the same thing. Only two other possibility would be a bent fork and a worn surface on the throw out bearing or/and the contact to the "fingers of the pressure plate. So it's a clutch job on the TC and getting "phyched" up for it. Did I mention 3 weeks ago I started... did I also mention I just turned 70. Today I just split apart the engine and tranny... tomorrow I will be dropping the tranny, taking the pressure plate off, and installing the new pressure plate. Oops forgot I have to buy 6 new bolts, recommended not to use the old ones for more accurate torquing.

Congrats, jack.
don’t fret about your age, I’m ten years behind you and landed a 2012 tC.
check out my bio.
I'm a Chevy man myself. My first car that I bought in my senior year was a '67 327, Chevy Camaro. Had a 2 speed powerglide that I changed to 4 speed Muncice M21, Holly 650, Edelbrock Hi-rise. Loved the G-force. Unfortunately, due to hard times had to sell it around 2012. Yeah the Scion is great fun, though I no longer go radical for all out power. The age thing is a fact that I have to contend with that I no longer have the strength to bench press the tranny into connecting the engine. The Scion tranny install in the connection to the engine have 3 obstacles in lining up, the rear motor mount, the pilot shaft, and the bolt holes. The trans/axle does not have a flat bottom for a floor jack which makes lining up very difficult. Yesterday I spent 3 hours with no success, today I'm psyching myself up to tackle it again... I'm determined and confident I'll be able to do it. I have pixs on part of my process that I'll share later.

Chevy man here too! Impalas, Novas, Monte Carlo, Camaros. I had a 69 Vet, 327 Muncie rock crusher four speed.

I’m going to have my Scion manual trans diagnosed because of a bad whine noise in every gear. After a full clutch replacement it’s still noisy. I suspect it is the spline shaft from the trans into the clutch throw out bearing.

Whining noise in all gears, sounds like trans/axel (rear end gear box in our rear wheel drive) or CV joints (any detoriated rubber boots). I would check gear oil if it is to level, or drain and refill... see if there are any metal particles in the drain.

I know it’s the transmission because while the car is rolling and you pushed in the clutch, the sound speeds up or slow down depending on the high or low gear I’m in.
You did a clutch job already... did you change the throw out bearing? If you step down on the clutch and you hear noise when you do, it's more than likely the throw out bearing. Definitely throw out bearing if you don't hear the sound when the clutch is released. Common practice is to always change the throw out bearing with every clutch job.
