Consensus is always composed as a matter of opinion. Looking through threads, many on here have experiences problems after a fluid change, i.e. Trans fluid is a high detergent fluid, after a change, dislodges debris within the tranny. The debris could clog up passages for the fluid to circulate, starving the tranny of fluid in critical places. Is it 100%? No... it doesn't always happen and I am sure those who have changed their tranny fluid have experienced many miles of trouble free service and really don't voice the success. But those who have changed the fluid and experience failure, you can bet that they will always broadcast it.
While I agree fluid changes are necessary... I do not agree with having to spend a few hundred to change the fluid on a working transmission, then experiencing a failure and spending a few grand to fix it. Again, matter of opinion. If it ain't broke, don't fix it.
