Auto gearbox oil change

[The Hoffi]

Hi all,
I am thinking of changing the oil in my auto gearbox but couldn't really find the right parts for it.

What parts do I need? Usually it would be a filter and the sump seal for the gearbox plus ATF oil.

Any special advice on this endeavour?

Thanks!

If you couldn't find any info on here about replacing the transmission fluid then I suggest you take your truck to a garage.

@Bushwacker: In case my search attempts were wrong could you kindly post a link to an existing thread where EXACTLY my question is answered? Would be much appreciated!
