Just bought a 2007 tundra

I just bought a 2007 Toyota tundra Sr5 full four door 2wd unfortunately, it dose not have a speck of rust. It has 192k should I do anything to it like change the trans fluid I heard it could damage it. It’s had a oil change every 5k miles. Should I change my spark plugs?

also I’m looking for parts like a tailgate any pointers? Im in Tennessee.

 

drain & fill, no flushing. if you're worried about spark plugs, take them out and lookatem. did it come with any service records? or a carfax? carfax will contain a lot of service records too

 

Thanks, yeah I checked it there wasn’t much information.

 

the only thing to do to make sure everything is good is get it done yourself. "baseline" as people call it. oil change, trans drain & fill, diffs, transfer case, spark plugs (they're cheap)... youtube is a treasure trove of how-to DIY videos.
