Thank you so much mate. My 2012 1.4t LT is at 152,000 miles...I just repaired 3 leaks in the coolant system and drained and changed coolant while at it, which is done every 150,000 miles from what I know. But thanks!

the 6t40 trans really just needs extra care and love to make it run good for a long time. That and an aftermarket transmission cooler should really be recommended for them. It'll extend the fluid change intervals and allow for it to take more power.

Spark Plug Replacement
Huh! My Owner's Manual for my 2012 Chevy Sonic 1.4L Turbo shows the plugs need to be replaced at 97,500 miles, not 60,000 miles. I wonder if there's a service bulletin reflecting this change (I'll have to ask my service department about this). It's also the same for the Severe Service too.

Amending my Owner's Manual from 97,500 to 60,000
Well, everyday you learn something and I'm glad this forum is available!
I'm going to go ahead and add the change to my Owner's Manual and schedule to have my plugs replaced. Thanks!

If you are modified, I would adjust this interval every 40k from every 60k. If you're stock, Keep to the 60,000 interval for spark plug service.
If you have an automatic trans and the car is stock. 30,000 miles for transmission fluid and flush. If modified, I'd do this every 15,000 or add a transmission cooler. I will be doing a write up on how to add one now that I'm replacing my transmission at 70,000.
Inspect axle seals and other items such as cam sensor seals every 10,000 miles. These are common items to replace on the LUJ/LUV/6t40.
Replace the serpentine belt every 40,000-60,000 miles. Mine is showing signs of failure after 50,000 miles, but really started getting noticeable around 70,000. There should never be a faded white line down the center of the belt. So these belts will probably end up splitting down the middle if they get too worn.
