2002 Diamante Trans (F4A51): 15 bolt trans-pan, removed pan& wondering where filter is? Numerous Auto Parts stores say it's an external screw on filter (looks like an oil filter). Can anyone tell me where it is? Much Thanks!!!

 

Here is a pic of where the trans filter is... hope this helps

 

you car does not have a servicable filter. The early cars did have a secondary external screw on filter which was deleted around 99, as it proved to be more trouble than anything due to peoples neglect.

the internal filter is designed for lifetime service, and you need to remove and disassemble the trans if you wished to replace it... but it doesnt need replacing.
all you need to do to maintain the trans is drain and fill it, which is how nearly all automatic transmissions have been for decades.
