fluid changes

[amp19]

What's the interval for these two services for avg driving habits? The maintenance schedule indicates 'inspect every 10K or 12 months' but not finding what mileage or length of time to give them a change:

differential fluid
manual tranmission fluid

Also, is it really 5 year / 75K for coolant & 126 months / 105K for the sparks as it states?

Appreciate the help!

I think it depends on how you use the car. If you drive it hard or beat on it I would say often. My car is modded with bolt-on's and tune and I just ordered plugs. That I will do every 20k miles. Coolant I will flush and fill between 30k-50K same for brake fluid. Diff and Manual Trans fluid probably every 2 years id I don't track it. If I track it I will change before track day and after along with plugs and oil. Honestly never looked at the schedule in the manual, this is JMHO

50k unless you’re a nut. Change it sooner if it bugs you.

nothing too strenuous in terms of driving habits. 2 years sounds about right for diff/manual fluids.

30-50K for tranny / lsd.

i have a ‘14 tacoma 4x4 TRD OR 4.0L with 200k miles. never touched the spark plugs / power steering / brake / dif fluids. For the coolant, i just keep it topped off over the years - i just finished off the 1 gal of toyo coolant i bought 10 years ago.

I change the oil & filter every 7-10k and i have changed the auto tranny twice - although the manual calls for no change on the tranny with an * which states every 60k for ”extreme conditions”. only had one repair so far - i replaced the alternator & belt because the bearings were starting to chirp at ~170k.

The Z Sport comes with an open differential so there's no clutch friction material to accumulate and need frequent gear oil changes. Manual gearbox oil does deteriorate but not very fast. Lots of S-Mode downshifts might warrant more frequent changes.

Long life spark plugs for forced induction is one of my favorite urban myths. The gap opens up significantly after 50k miles and new Iridium plugs at 30k is my plan. I've seen high mileage plugs run without misfire in a boosted engine but cold morning starting became almost instantaneous with new ones.

I'm every 10k miles following the severe driving maintenance schedule

I changed my MT fluid at 7500 miles to Redline. Why? Cause I'm a nut.

Went with a factory LSD. Did NOT come with a breather installed. SO, I slapped the Z1 diff cover on, and put Redline in there too.
