PCM transmission fluid extraction...How

[Dr.John]

I am trying to extract the ATF from my PCM 1:1.23 transmission, and I can't get the pickup tube to reach the bottom. I am using small (1/4') tygon tubing and it either is curling out of the way or is blocked from fraching the bottom.
What do you use?

If all else fails there is an allen head drain plug on the bottom. thats what i've used to drain in the past.

I'm not good at standing on my head, and I also was trying to avoid a mess :mrgreen:

If I can't find another way, I'll go for the wrench! 8-)

The 1/4" tubing should work, sometimes is just a matter of probing around inside the tranny to actually get to the bottom. As long as you're not forcing it, it shouldn't hurt anything.

I was wondering if anyone uses a metal tube? It looks as though the dipstick goes through a small (~1/4") hole internal to the transmission, but I don't know if it goes to the bottom or not.

Did it with a small metal tube attached to a piece of tygon tubing. Fit down inside the hole that the dipstick goes through. Griots Garage has a vacum unit with the metal tube already on it. You just have to straighten it out. Worked better than my wifes turkey baster.

With such a slick way to drain the engine oil its a shame there isn't a better way to do the tranny fluid.

Hey thanks! I had a feeling that this would be the case.

It should work the same and as well, the omission is just a cost saving measure is my guess!

I have used a shallow baking pan to drain the tranny and then suck it out of the pan. It seems like over kill but it is quicker than cleaning the bilge. You can actually make a pan out of heavy duty aluminum foil.

I bought a Pela (I think it's spelled Pela) oil pump from Overton's. the hose that came with it is smaller than 1/4 inch but I don't remember the actual size off the top of my head. The hose is farily rigid. It sucked out the 2 quarts in less than 5 minutes. I did need an extra hand to keep the hose in the bottom though as it tended to curl up and out of the trans. It sure would have been nice if they put a hose on the bottom of the trans though.

after dumping mine in the bilge , i went to my friends house to help him with his boat , and he pulls out 2 walmart bags and put them under the v-drive and let her rip . it worked perfectly , didn't spill a drop. i'm still trying to get that mess out of my boat.

I used a 1/4 inch pipe (the kind for an ice maker on a refrigerator) stuck it down in the small hole for the dipstick (not just the big opening at the top but the small one that the bottom of the stick goes down in) and ran the other end of the pipe down and out of my drain hole. I used my mouth to get a siphon going (since the tube was clear I didn't get a drop in my mouth :-) and let it drain into a bucket. It took awhile but got almost all of the fluid and once it started didn't require any attention. I checked it later in the day and put the new fluid in.

hmm,

I used a SS 1/4 tube that fits all the way down into the tranny, I leveled the boat in the driveway and then used a hand pump. I only got about 1qt and maybe 1/5th more. Anyone replace the drain plug with a fitting like the oil pan? Also, anyone "T" off the V-drive line. I like to change fliuds regularly and would do all three every 25 hours or so if it were more convienient, but today the tranny and V drive are a pain .

[mike-d]

hsmunoz,

I too would like to change fluids more often, but the vdrive and tranny are a pain. I will see if its feasable to tee off the plugs ala oil pan,maybe an automotive tee plug?

I bought a contraption called "SuckUp" from skiDIM. It's basically a big tank that you pull a vacuum on with a hand pump. Then you stick the small hose down the dipstick hole and release the vacuum. The tranny fluid is then sucked into the tank. It worked great and I had my tranny sucked dry in about a minute

I got the same SUCKUP, aside from the catchy name, it worked well on the motor and the trans. I got 4 quarts out of the engine no prob and about 2 out of the Tranny without too much hassle. I did work the tube around in the dipstick hole to make sure it was getting the bottom, same with the engine. You can hear when it's sucking air so you try for every last bit. I figure the 50 bucks for the suckup will pay for itself in no time at all.
