2.) You state that a flush is unnecessary unless the fluid is discolored.
1.) Usually starts by approaching the filter from the top, thus FU the MAF connectors and whatever else they touch. If from the bottom, then the under engine tray is only undone on one side and bent down. If they are smart enough to take it off, they are not always smart enough to reinstall it, especially with all the fasteners.
You really need to read some previous posts. It's all documented there.
2.) Not at all. To the contrary, it is best changed before there is any discernible color or olfactory detectable change, which disappoints technicians to no end when they cannot show brown fluid being extracted. When there is visble color change via the white papaer towel test, then the transmission is overdue for new fluid and damage has occurred.
Minimum wage Pit Monkeys can do hundreds of dollars of damage in just one visit. Good to converse with them first to see if they are cogent beings and understand enough English to follow instructions. Never be afraid to tip for good service. Of them all, JF is the worst. Of the reamining competent better ones, you usually won't save money over the dealer's service, and the dealer will have a tech look at it while it is on the rack for any likely problems. Their kids wear shoes too, which cost.
