Using a drill pump to drain Tranny fluid

My tranny intake tube is at least 1/2"dia., using a smaller tube would really be a limitation of your pump (so you don't overheat it). As for doing it like this, you don't get anything out of your torque converter this way. I hope that you intend to change the filter, eventually.

I bought a Mighty-Vac hand pump at Sears. K-Mart has the same one under a different name. Under $10 and has all you need.

I have two pumps and a primer mounted on a square plastic box containing a receiver reservoir. It's handy to do it this way and clean. I even suck the fluid out if I'm pulling the pan because it's so easy. I vow that the next time that pan does come off there will be a drain on the pan.

I don't know whether this is feasable for your vehicle, but I purchased a Hayden kit for connecting an auxilliary transmission cooler. It consisted of two barbed fittings that screw in where the steel transmission lines attach to the radiator. On my Yukon, I removed the upper line and installed the barbed fitting there with a 5' piece of hose leading to a bucket. Start the engine and the trans will pump out fluid faster than you can pour it in. I pumped out 24qts. and refilled the same amount the last time I did this. This is what I do in between the recommended filter change intervals of

I've used a hand suction pump to remove most of the fluid from the transmission pan so that I would not generate a mess when I dropped the pan. You still need to drop the pan to change the filter, get the dregs of fluid, and clean the filings off the magnet.
