OK, don't laugh... I changed my fluids yesterday and it turned out to be a
fiasco. Oil went fine. Hard to screw that up. Dropped the tranny pan and I
am glad I did. There was the typical metallic at the bottom like all
new/rebuilt trannys do. Got it all cleaned up and ready to go back together
w/a FRAM FT-1019 filter kit ($27... proud of 'em, ain't they?). Old one came
right out w/the o-ring. Looks same as new except it has copper inlet and
outlets. Much nicer than the FRAM.
OK, put the o-ring on FRAM and hmmm.... won't seem to go in. Got the
caliper out and mic'ed the inlet. Bit bigger (not bad only a few
thousandths) so I filed and emery clothed it. Worked on it for 2 hours and
still could not get that thing up there. Every so often I'd put the old one
back in just to be sure I wasn't loosing my mind and every time it would
slip right in place. I even went and got another filter from some off the
wall mfgr. It was bigger yet so it was worse. Put it right back in the box
for return.
Finally as night fell I decided to put the old one back (yuk) and button
it up so I could clean up the mess. My question is does anyone know the Mfgr
of the copper tube filters? My next step is to goto some of the trans shops
(Aamco, etc) here locally and ask them. Anyone had this silly problem before
or is it simply my luck running true to form of late?

OK Nate - Not laughing here! I also bought the Fram, and when I pulled out
the other installed filter, the Fram just didn't appear to be comparable
quality. (My totally subjective opinion). I returned it and found an AC
Delco that IIRC, had the copper tubes. Notes from by file read:

ATF - AC #TF-169 (or #12339142?) {Try Classic Automotive Supply?}

Now if you want to laugh, the first time I changed mine and installed the
Rausa pan, I was real proud after getting it all RTV'd and back together,
with fluid installed. As I was walking back into the garage, I noticed the
new filter still laying on my work bench! I was able to test that Ragusa
drain plug sooner than expected.

Nate,
The last two times I've changed the tranny fluid I bought the filter from Advance
Auto Parts (in Chattanooga). Their "PRoformace Filter Kit" includes a Saginaw
FK117 filter and Felpro transmission pan gasket. I believe the kit part number
is 34651 and I got it overnight through Advance's PDQ service. It costs about
$18 vs. about $29 for the genuine Delco part IIRC. The filter was stamped
"Taiwan" so I when I got the old one out I cut it half with my hacksaw to see
what was inside. There was multiple folds of filter media inside with metal
baffles to route the oil through it. The tube and new o-ring fit nicely in the
the transmission without any problems. Overall I'd guess that this filter is
adequate for the GMC, given that it and the oil get changed every 12,000 miles.
If you've got an Advance Auto Parts near by you might try this kit. Good luck.
