I realize this will trigger some mechanics but anecdotally, it’s never been an issue for me. I’ve also never heard of anyone developing transmission problems as a result of not flushing/changing their fluid.
Transmission flushes have been around for 25-30 years. Completely unnecessary in the majority of cases, but takes about the same amount of time as a drain/refill and they have to 'hook it up to the machine' so the service is more expensive. It's just an up-sell for increasing profits.
But it's an easy sell...a normal drain/refill only replaces 50%-70% of the fluid (depending on model and type). Don't you want to get ALL of the dirty fluid out? Of course you do...sign here.
But ATF is not engine oil. It's not critical to get every drop out, particularly if regular maintenance is done.
As I mentioned in my first post on this, sometimes issues appear after a service. But rarely due to lack of service, assuming the proper fluid level is maintained.
Re: Leaks after service
If it leaks after service, that's 100% on the tech doing the work. No magical leaks appear if pan gasket is installed correctly.
