Sorry for starting a brand new topic, it's actually connected to
http://www.omegaowners.com/forum/index.php?topic=55239.msg833026#msg833026
(that one hasn't been touched for 4 years, so I decided to start a new topic)

So :
They say brake bands of auto gearbox should(must) be adjusted after changing ATF.
E.g. :
http://freeasestudyguides.com/transmission-brake-band.html

"...Some bands need adjustment; this is typical with older transmissions.
One end of the band is held with an anchor pin and the other a servo piston.
The anchor pin is where the adjusting screw will be found...."

Now, what exactly am I to do ?

Does this job need a mechanic and 1.000.000 $  ?
I hope it doesn't.

Is it maybe this screw ? :

The brake bands are inside the body of the transmission - getting to them (and adjusting them, if that's even possible on the GM gearboxes) would require near complete disassembly of the gearbox..

You'd have to take it to an automatic transmission specialist and pay a considerable sum for that kind of strip down.

I've not heard of anyone doing it on these (relatively modern) gearboxes..

Well, then, what is THAT screw on the picture ? :O)

[Jimbob]

It has been covered on here before...somewhere...

You need to remove the sumps
there are then 3? screws holding a dome like part on
under here is the screw to adjust the break band

its something like 5nm, then back 1 turn

so very tricky to accurately set.

this is all from memory, so dont rely on that info.

Try searching for "4L30E brake band adjustment".

I found this rebuild guide http://scottj.info/files/isuzu/4l30e.pdf

On page 108 it says that part #7 is "plug, converter housing"

HTH

[TheBoy]

I have never adjusted bands after atf renewal. Doubt anyone else has either...

If your just after servicing the box ATF and nothing is wrong, leave well alone. If it ain't broke don't fix it, but do service it.

If your getting any slippage or loss of drive then look further, but you'll need to remove the valve body as well(metal "panel" with oil ways and solenoids and wires screwed to it)

If it's banging into gear or thumping, then ATF change will sort that, usually. Don't touch the brake bands for that issue though.

What you've artiste would appear to be on the bell housing? There nout in there to adjust, even if the brake bands where accessible from outside the box, which the ain't!


Who told you to mess with brake bands anyway?
