Yank 3600 Torque Converter Learning as i go with my 01 TA. I am going to install my 3600 torque converter, I know i need to put 1qtr in the converter before install like ATF in either a Dextron III or a Type F. My question is: By pulling the transmission down, will a lot of trans oil leak or hardly any? Should i purchase a few transmission Quarts to add to the transmission after the install? What kind of transmission oil?

DO NOT used Type F fluid.
It will be hard to get a full quart of fluid into the converter. When filling the converter, the fluid level will creep down after filling. I just fill to the base of the hub and leave it at that. In my opinion, all that is needed is a little fluid in the converter to lube it for a few seconds until the pump can fill it.
As to the amount of fluid you will need will depend on how big of a mess you want to make on the floor. I have never been able to remove a trans from an f-body without removing the dipstick tube from the trans case. When removing the dipstick tube fluid will run out onto the floor. I feel it is best to remove the pan and change the filter while the pan is off. You can figure that the converter will hold 2 to 2 1/2 quarts and the pan will hold 4 to 5 depending on the pan that you have. I would also blow or flush the cooler lines and cooler so add 1 quart for that. So, 7 to 9 quarts will be needed.

I would change the Fluid and Filter to be on the safe side at this point since it's coming out. Pull Pan, drain it all, new Filter, Pan back on, then drop it and put the new Convertor in. It'll be a subasantially less mess. New Convertor in, back in the car then put 8 quarts in. Turn the car on add a quart and check it, go from there.

As mentioned DO NOT USE TYPE F IN A 4L60E E PERIOD .
As for filling converter I am really not big on this, Truth is the converter will be full about 10 seconds after you start the car. Some say it soaks the clutch but that will happen pretty quick to while you finish filling check for leaks and run through gears preferably with wheels off ground before test driving.
Back to TYPE F it does not have the correct friction modifiers for a PWM type system . If you use it you will likely get converter chatter on lockup which is not pleasant.
My preference is DEX6 but dex three up is fine.

I would get a case 12 quarts just to have onhand. and a dex 3 or better as I said I used DEX 6 . This assuming trans and converter empty.

Agree brand not really important, I personally use DEX 6 and synthetics are awesome IMO

Dexron III/Mercon will work just fine. I have a 3quart deeper pan (B&M) and for me it was a 12 qt change. I am not a proponent of Dexron VI synthetic fluid in a 4L60E. I change my fluid every 25K (10 years), Sara (2001 Z28) is a garage queen.

The transmission performance shop that rebuilt my 4l60e that can take up to 550hp informed that i should use synthetic, i initially bought dexron iii but i am sending that back and got dexron vi synthetic. I bought 3 gallons.
