thats why i have 70k left on my warrentyI was told by the Service Dept too, that it's sealed. No need to check. They will "check it" when it's time to service. If one is loosing trans fulid, then there is a problem - we all know that.
How lucky will be to catch it as it starts?
Not likely. Even the best of us, let's say check it every two weeks. Look fine on day 1. On day 3 a leak started, and the trans be gone on day 4. $3,000!!!!
