Hey guys I tried digging up what should be checked and replaced @ 100K but cant find anything.

2007 Corolla
TRANSMISSION FLUID
TIMING BELT

Besides the basic oil, and brakes.
anything else that I should check out?

It runs fine, and is our beater car.
we have 2 other vehicles but don't use them much

I think its 97-present corollas have a chain, not a belt so your good on that.. A 105k service is usually this;

Plugs
Wires
Oil
Trans service
tire rotation
Serpentine belt
tensioner

Check your owners manual, usually they list the suggested services at milage intervals.

Yea for some dumb reason I cant find the manual and when I searched for it not much is comming up.
most of that I can do by myself.
I appreciate it
