Just want to double check, when changing the tranny fluid, you need to disconnect the fluid supply line, which brings the cooled fluid back to the tranny. Anyhow, when you disconnect this line, do you disconnect it at the radiator end? Or the other end?

i thought u just dropped the tranny plug, let it drain and refilled it?

If you're just draining it from the plug, you only drain about 4-5 qts of it, which is about 50% of the fluid. After that's done, then you drain it from the supply line, that way you'll get the rest of it and have pretty much all new fluid in there, instead of a 50/50 mix of old and new.

i thought you can't drain all of it unless you drop torque converter, cause half of it is in there????

You can get all of it out if you start the engine and pump it out throught the supply line as suggested above, this will get all of the fluid in the conveter as well. Do this of course after you drain and refill the pan and do it 2 qts at a time. See my homepage for instructions.

It's easier to disconnect that line from the radiator that way you have the hose to pour the fluid into the container. If you did it from the trans side, it would make a huge mess.

Edit Add: It's easier doing the way I said if you are putting in a trans cooler, but, if you are flushing your trans, then disco it from trans side.
