Hi guys

Ive bought the truck at about 90k km
Did oil changes
Changed the rear diff fuild
Cleand the throttle boddy and the air filter
The truck now at 120k
And im wondering what else should i do
Wanted to change the trans fluid but its still nice and pink the guy at the shop said the same thing.
Second thinking that
I use the truck for work and got a metal canopy

Appriciate all feedback

with 120 i would change the trans fluid as its one of the most over looked things. change it before it starts getting burnt. also dont do a flush, even gm says not to do a flush. if you have an owners manual there should be a "maintenance scheduled" and do all those things assuming it hasnt been done before

Be a good idea to change the coolant out, unless it's been done. and also flush the brake fluid system out. It's hygroscopic, and should be changed at 3 to 5 years.
Might be time to change out the serpentine drive belt too. Also apply some white lithium grease to your door hinges.and perhaps some graphite lock oil to your door locks.
