Installing a rebuilt 4L80 transmission:
Do I pour a QT of ATF into the bone dry Torque convertor??
How much does a bone dry 4L80 get??
Should I run synthetic ATF??
And I am under the impression I put a few QTs of ATF into the transmission, and then before starting it check to see if my dip stick is reading full…??
And as my oil lines and coolers are not dry should I flush them before running the new transmission?
Note the old transmission was running fine so there is no junk in the fluid. I am just upgrading from a 130K good 4L60e to a fresh fully upgraded rebuild 4L80e with a rebuilt torque convertor.
Thanks for any and all help.

And Yes this project HAS taken 3+ years..and dreamed of and planed for about 29 years. The engine build was started in 2004.
Frankly after the first year 3 years ago I began having poor health, and this engine and transmission with a swap from a 4L60e to a 4L80e with an add-on US Gear Dual Range overdrive is a nightmare job, new transmission mount new drive shaft, etc. All the hook ups a swap of PCM etc. A major Herculean task!!
And an engine swap from a TBI to a TPI system with ALL the problems of converting the Vans PCM, hookups, is also A Major Herculean task.
Then there is my plan on rebuilding the interior, for the third time, changing the bed, from a single to a queen, rigging a stand for my sleep machine, and a batter system to get a full 8 hours if not AC is available, putting in a window heat pump, rigging a start stop thermostat controlled engine system so that we can have either heat or cooling from the vans own systems when we cannot get a hook up of 120V AC for the Heat pump.
Then there is still a worry about all the hoses and so on after sitting for over 5 years….
And my plan of switching from an engine drive fan to an electric fan system from my 2000 Mercury.
And I think I need a special Hydro power steering and brakes pump.
Quite frankly I fear I have taken on more than I can handle.
