IDK what's going on, but I agree with your issue. Seems like a short change
interval to me too, given that auto trannys are mostly filled for life now and
sure get used a lot more hours and harder use than a lawn tractor. I wonder
about the filled for life concept too, where you can't even check the fluid level.
You would think some of them would develop a leak and if you don't realize it,
something very bad would happen. I wonder if they have a level sensor or
similar to warn of impending disaster?


"filled for life" in modern car automatic transmissions ?
.. are you sure ? not CVT transmissions of course
Got a link ?
