30K mile service recommendations

I use this on all my vehicles, effortless, doesn't spill a drop and threads directly into the diffs and various transmissions just need a cordless drill. I got the same one off Amazon.

When should the spark plugs be replaced?

I plan on adding A/T fluid exchange on the LC. I want to get the loose friction plate material out - as there is a lot going on making debris in that tranny w/ lock up converter & 8 speeds. I’ll do an initial tranny fluid change @ 10K miles, then every 20K mile intervals after @ 30k, 50k, 70k, etc. I’ve done it on my Tundras & plan to do same on our LC. I occasionally tow & wont take a chance. Also recommend pulling the secondary gauges up on the IP so you can watch your engine oil & tranny temp. Highest temp I’ve seen on 10 spd Tundra wasn’t towing, it was in a brutal 2hr rolling stop n go traffic jam going through Houston.
