About to do my first big mechanical repair on my 2001 Celica GTS. I got the car a year back and it has had problem after problem. BUT! Replacing the clutch should be the last thing needed so I can start daily driving it.

I wanted to ask while the transmission is out of the car, what are some other preventive maintenance things I should look at? we are currently doing clutch, flywheel, and throwout bearing. Anything else we should look at?

Also do you guys have any recommendations for parts? I got an idea for the clutch but the rest is up in the air
