370 automatic gearbox oil and filter change

[Walker]

On the 370 auto gearbox as any one changed the oil and filter with after market filter and had problems removing filter holding fasteners or retightening them 

some one said don’t change it because one of the fasteners is held with a nut inside the spool which turns so you can’t retighten it 

thought  they  were all set screws 

mines done 30k so would like to change oil   Thanks

Done it. No didn't encounter any blind nuts, it would be a pretty stupid design if that were the case.  I do recall the screws are 3 or 4 different lengths, I made a piece of cardboard with holes where the screws fitted so I could put them back in the right places.  Don't overtighten them, I have a 1/4" drive inch pound wrench for this small stuff.
