I have 156k on my auto tranny so I decided to do a ATF change.
I drained about 4 quarts out of the tranny. The manual says the capacity is 2.0 quarts, so the other two or so quarts must be from the TC. I put in 2 quarts and it says its full now. If I drive it will the level go down and pump the fluid back into the TC ?
Also I was doing to reading and it looks like people say not to change the fluid on high milage trannys because the old fluid contains a bunch of the old friction material and the fresh fluid will allow the clutches to slip. Is this true ?

 

it actually varies...just refill till u get to the full line... theres a cold and hot side so make sure ur checking respectively... BTW i usually get 2 - 2.5 qts everytime i drain and refill

 

I also get between 2 and 2.5 quarts out of the pan when I drain my transmission. To my knowledge, there is no way to drain the torque converter unless you pump it all out of the line going to the radiator.

Just my $.02

 

first

ok you put the 2 quarts ..it was full ...run the car at idle ....check the fluid ....see what the level is

Check the Automatic Transmission Fluid (ATF) For Solid Performance
Your car’s automatic transmission fluid is a key element to keeping your car drivable.

* Among other things, on a day-to-day basis transmission fluid: Cleans
* Cools
* Lubricates
* Transmits force
* Transmits pressure
* Inhibits varnish build-up
* Protects the transmission

You check your automatic transmission fluid much the same way as you check your engine oil: Remove a dipstick from under the hood and inspect the fluid level. The dipstick for your automatic transmission fluid may be labeled TRANS or ATF; it may also be colored bright yellow or another color for easy recognition.

In most cases, automatic transmissions must be checked when the engine is running and only after it is warmed up. Driving the car 10 miles or more is the best way to properly warm it up.
Checking the ATF Overview:

* Park the car on a level surface.
* Leave your foot on the brake, keep the parking brake on, and let the engine idle.
* Move the gear shift through each gear. This will ensure that the hydraulic chambers in the transmission are filled with oil. Also, checking the level with the engine running allows for fluid to be circulating normally. By not following this step, you will get an incorrect reading.
* Note: Sometimes, checking your fluid with the car in park or neutral is required. Consult the owner’s manual for more information, or some vehicles have the instructions on the dipstick.
* Locate the transmission dipstick, usually placed at the rear of the engine. Pull the dipstick out and wipe it clean with a paper towel or a rag. Be sure to note the markings on the end of the stick that indicate fluid levels: "FULL" and "ADD 1 PINT".
* Also check the fluid for black deposits, metal particles and dirt. Do this by wiping the dipstick with clean a white paper towel and examining the fluid on the paper.
* Also check that the fluid is clean and transparent, not black and/or having a burnt smell.

To add transmission fluid:

* Only add transmission fluid if it is at or below the “Add” mark. Never fill it past the “Full” mark.
* Be sure to only use transmission fluid that is recommended by the manufacturer. Consult the owner’s manual for this information.
* Transmission fluid is usually sold in quarts. Do not add the entire quart at once; add small amounts at a time until you get the correct reading on the dipstick.
* Use a funnel to get the fluid into the small tube that the dipstick came out of.
* Wait for the fluid to settle after adding it.
* After a few minutes, start the vehicle. If it still is not reading the correct level, add more fluid.

good luck let me know how you made out
