Maintenance

Almost at 40,000 miles on my ‘22. Was thinking about changing front/rear diff fluids, transfer case fluid, but can’t find solid information in the manual about weight/capacities for this.
Has anyone changed theirs?
Also, thoughts on having transmission fluid changed? I don’t think it should never be changed as the manual indicates

Some good info in the this thread on another website.

Maybe stop by a GM dealer and ask the parts department what is recommended for your particular vehicle.
