Does my auto tranny have a filter?

Is it like a domestic service where you just drain fluid, drop pan change filter and gasket?

Calls to the dealer are met with angry service ppl saying they "can't" tell me the details, and that I HAVE to come in to service the vehicle...

If your dealer is telling you that then you have to go elsewhere.

2001 and + Elantra don't have a filter on the tranny, you just need to flush it at maintenance intervals.

Thank you Jalmir :)
