Everyone has given you excellent advice. The only thing I might suggest is to make sure you can easily remove the upper transmission line ahead of time while the car is still cold.

I always flush my transmissions at operating temperature. Perhaps I am wrong but I think it increases the possibility of having any particulates in suspension when the fluid is pumped out. By being sure the line is easily removed you don't have to fool around handling it while wrestling with getting it loose. Hold the fitting on the radiator with one wrench while attempting to loosen the cooling line with the other. Be careful handling the old fluid while it is still hot. Good luck.

Dear EJO,

Good p.m. and may this find you well. You'll need:
12 Quarts of Mobil 1 Synthetic ATF (System capacity is 9 Quarts)
8 feet of 3/8" (10mm) Internal Diameter clear vinyl tubing
4 one-gallon plastic milk jugs (empty, clean, and dry), with screw caps
2 10" adjustable wrenches, or open-end wrenches
1 funnel with tip that will fit in the tranny filler tube

Using the 10" adjustable wrenches (or open-end wrenches), remove the upper transmission line from the ATF cooler (on the side of the radiator). Use one wrench to grip the hex fitting on the radiator. Use the other wrench to turn the fitting at the end of the transmission fluid line. Be sure NOT to let the wrench on the radiator hex fitting move at all: this will damage the radiator. Loosen the fitting at the end of the transmission fluid line and pull back on the line, gently, to separate it from the radiator. Push the transmission fluid line slightly aside (use a cable tie to hold it, if necessary).

Take the 3/8" diameter plastic tube and push one end of it over the nipple. If it won't slide, lubricate it with a bit of ATF. Put the other end into an empty milk jug. Put the end of the tube into the bottom of the jug. Put the milk jug inside a bucket (to catch any ATF overflow). Place the bucket on the side of the car, where you'll stand, when you add ATF.

Remove the transmission dipstick (yellow top), and put the tip of the funnel into the filler pipe. Press down firmly on the funnel, so that it stays in place. If need be, use some wire to secure the funnel, so that it doesn't come out or fall over.

Open two quarts of Mobil 1 ATF. Put the car in "Park" and set the emergency brake. Turn on the engine, which will cause ATF to be pumped out of the system, into the empty milk jug.

Immediately start pouring Mobil 1 ATF into the funnel. When the milk jug is half-filled, turn off the engine. The ATF will cease to flow, after a few seconds.

Open the next two quarts of Mobil 1 ATF. Turn on the engine. Add ATF via the funnel, as the milk jug fills. When the milk jug is filled to two inches from the top, turn off the engine. The residual ATF flow will fill the jug. Cap the milk jug and take it from the bucket. Set it aside. Put the next milk jug into the bucket. Insert the plastic tubing into the milk jug.

During the filling of the next milk jug, have your helper move the shift lever through the gears, leaving it in each gear for a few seconds. That will allow the fresh fluid to circulate completely and to flush-out used fluid. Your helper should keep his//her foot on the brake, while doing this. You might also want to chock a rear wheel.

Repeat this process, until you have filled two (2) milk jugs, and half of the third milk jug. You will have used 10 quarts of fluid. By then the fluid coming out should be a nice, clear rosy red. Turn off the engine. Remove the plastic tube from the radiator nipple, and re-connect the transmission line.

Remove the funnel from the filler tube. Check the fluid level. If it is over-filled, re-disconnect the transmission line from the radiator, and pump-out some more fluid. Re-connect the transmission fluid line to the radiator.

Turn on the engine and check the fluid level. Fill it to the level indicated on the dipstick. DO NOT OVER-FILL! If you over-fill, pump-out the excess, as above.

Most places that service transmissions will take the used fluid from you at no cost, so long as it is uncontaminated by water or gasoline.

Hope this helps.

Yours faithfully,

You'll need 12-13 quarts of Dexron III, 3 empty gallon milk jugs, a funnel with a long, slim neck which will fit into the tube where the transmission dip stick fits. All auto parts place should have this funnel.

You'll need a clear vinyl tube which will press fit onto the upper radiator nipple where the top transmission cooler tube connects. I don't recall the exact size of this tube but you can measure the nipple and figure it out. The tube needs to be long enough to reach from that top radiator nipple down into one of the milk jugs.

That's it, no special flusher needed. Connect the tube, have a friend at the controls, turn on the engine, let it pump out about 2 quarts, turn off the engine, add two quarts of new oil, repeat until you have gone through 10 or 11 quarts. On the last fill, it is best to under fill the transmission. Then reconnect the upper tube to the radiator nipple, drive the car until the transmission oil is at operating temperature and then fill as needed to the full mark. Do not over fill!

This is an easy job, I've done it alone. You don't really need a lift since the job is done from above the engine bay. The lift will be a great help in checking the wireing, etc. under the car though.

A true complete trans flush is done with about 13 quarts of oil. There is a machine that you put in line of the oil cooling lines then run the car in nuetral. the oil pump will push all of the oil through the systems getting caught in the machine and will draw the fresh oil out of the machine. See if the local community college doesn't have an auto program that you could take classes in to be able to use their tools and such.

This is one variety of the machine that you need:
