[V8] V8 transmission filter

I went through this about a month ago.  All of the FLAPS wanted to sell 
me the wrong filter for the wrong transmission.  Some VW 3 speed with an 
ameoba-shaped pan.  I looked around and found a ZF4HP24 filter set--two 
of them.   One without pickup tube, one with 1" pickup tube.  The 
ZF4HP24A used the V8's has, apparently, a deeper pan than the HP24 used 
in Jag's and MB's.  I found one out of Chicago:  $65 for the filter, $55 
for shipping.  I declined and my mechanic brazed the old tube onto the 
new filter.

He strongly recommended a flush.  He disconnected the cooler lines as 
they pass under the engine rather than at the radiator due to my wishes 
(long story). 

Since we were doing a flush and complete fluid refill, my 
wife-er..wallet-..er.. banker said that I couldn't do the Mobil 1 Syn, 
so I went with Castrol Dex III. 

Glad I did not attempt myself: 12 of the exhaust bolts had to be cut 
off, all 4 donuts were toast, that would've set me back DAYS.
