The changing of entire trans can be great or it can bite. Most of my experience is with Ford but picking up Nissan fast and how the corporations work.
Ford quit going into transmissions too unless only simple stuff, when they yank they commonly change out the entire unit as it changes everything to be able to say they truly have fixed it. The issue being many dealers do not have a dedicated 'trans only guy' smart enough to be able to fix every little detail and on ATX that can burn the dealer pretty bad, there being so many little things that can be missed one over and over to make repeat customer complaints. I queried Ford techs back in the '00s when I could not get ATX parts from them for a 5 year old car (NLA, ????) and they told me they pretty much never rebuilt anything at all back then, only changing entire units out. Not needing parts meant letting them run out of stock to be NLA faster. It made more profits doing so too.
It has become common to simply shove that onto other entities now in American business, the business model being to sublet the problematic work out to specialists who do that type of thing all day long and nothing else. The so-called 3rd party supplier then takes the hit there for the main company and it makes it easy for the 2nd party to put the blame off on somebody else, customers understanding then that the dealer 'got screwed' too just like the customer feels he has. It lowers bad customer feelings, them being the unlearned they usually are. What corporations look for nowadays, other companies that can take some of the losses off of them, the entire idea of the 3rd party company.
With the mystery of the CVT that will be done even more by Nissan I think. The main issue with CVT is that chain to pulley interface, it's the main wear item and you pretty much are going to be doing major teardowns to get that fixed, there is no way around it. Easier to contract that work out to somebody else to worry about and simply have lines of transmissions just waiting to go into the cars. That way you get out of having a high paid all knowing tech guy around all day who may be wasted when there is no work and it's hard to find them at the lower wages they want to pay now anyway. The CVT itself is an effort to do the same, much simpler inside to lower cost greatly but until they figure out the heat treats and materials needed to make the chains last longer the 3rd party rebuilder there will be taking the hit for Nissan as it changes them over and over.
