Transmission oil change due to time?

I believe much of what you say is fabrication and without facts, merely opinion. Purchasing is a procurement element of a company. Not a policy or warranty implementer. I deal with purchasing guys everyday of the week. Their job is to purchase what the engineers & manufacturing ask for. Sure they shop around for the best price, but end result is they buy what the engineer and manufacturing supervisors need to get the job done.

You throw out a lot of general comments that don't mean much of anything or follow any rational thought in regards to the original question that was asked. Just a bunch of straw men arguments.

My discussion is based on printed documented data and information. Yours is hearsay.
