Refill ATF... Tips?

I use Mobil 1 in the trans and since you can't find it in one gallon bottles, I saved an old antifreeze container, rinsed it out, and filled it with the transmission fluid. Any hand pump for 1 gallon bottles will fit just fine, so you screw it on, and pump away. It's a little tedious, but not really difficult. There are certainly worse maintenance procedures on a 928 to perform.

FWIW, my el-cheapo solution (since I already had a Mitivac):

IIRC, it was late at night when I was doing a tranny filter / fluid change and this was the easy way out rather than waiting until the next day and getting a proper hand pump.
Works just great. In fact, I've still got that empty ATF bottle (actually, just need the cap and hoses) out in the garage for next time.

So on same principle would it be OK just to fill my Power Bleeder with ATF and clean it afterwards, or would it be a real no-no for using subsequently with brake fluid?

ATF will wreak havoc on brake parts, similar to the possible damage to AT components that brake fluid might cause. But you may be on to something, especially with the costs of the little garden sprayers coming in just north of $10 at the high-dollar spots like Wal-Mart. Cut off the end of the spray wand, and slide some plastic hose over it and clamp it. (kinda like Jed but I was thinking more like Elly May...) Those little plastic wire ties mkae good hose clamps for the clear vinyl tubing. Anyway, that would let you use the valve to manage the flow of ATF as you fill. Pump the sprayer pump instead of the little gear-oil pump. Over three gallons of ATF for full refill, lots of pumping.

And a reminder that the ATF bottle cap has threads that perfectly match the replacement lawn-mower gas tank caps that H-D sells. Pass the tube through the cap or glue in a couple stubs of copper tubing for the hoses to slide on to, and add a vent/return line to the cap too. Route the return line into an emptied ATF bottle to catch the overflow. The junk screen MUST be removed from the reservoir for this to work, else the fluid will pass across the screen directly to the vent hose. If you decide to just push the end of the supply hose into the reservoir a little, leave the screen in place while there's any chance of crud falling into the reservoir.

Now, is there any harm in storing ATF in the Sprayer?

Auto fill
ATF is thin enough to pour fairly quickly so I just put clear tubing on top of the quart/litre bottles, squeeze into reservoir. For heavier fluids (eg EP90) into gearboxes, diffs, I have run a clear tube from filler hole to outside the body, attached to a funnel tied to the fuel filler flap, and watched for overflow, catch whats left in tube somehow. With the 928 AT, fill reservoir, start/stop engine, repeat until level doesnt drop significantly, then top off while running.

OMG
a suction gun is the only we do it in the shop and the way I do it at home

Suck it out of the ATF bottle and squirt it into the trans bottle.
Now that was easy

Not sure why you'd want to.
The auto trans is so incredibly sensitive to contamination that I'd hesitate to store the fluid in anything but capped original bottles. There's always the chance that ATF will swell the rubber bits of the spray pump if left in extended contact too.
My brake bleeder gets flushed thoroughly with detergent and water before it gets put away. I leave it upside-down to dry out completely before storing it. When I pull it out to use it again, it gets a splash of new fluid flushed through everything so anything that might be left in there has a chance to go to the waste bucket. Moisture especially.
My next fluid change (soon) will use ATF from gallon plastic jugs. I'll probably make a new fill cap for the reservoir with a hose nipple in it somehow. I will still use the bottle pump since I have it. For most of us casual drivers, ATF gets swapped every few years at most, honoring the 25k change interval recommendation. I have two filter and gasket kits on the shelf and the ATF on the bench, so I'll be doing it soon just to clean up the garage; last change was about 17k ago, and at the rate I drive my own cars it will take another year or two to get all the way to the 25k interval.

I picked this little pump at Harbor Freight last night. Hopefully it will come in handy when I change the ATF soon.
