I Just Installed A Seperator Plate And Would Like To Know What The Fluid Loss Was About When I Removed The Pan. This Way I Will Be Close When I Refill.

Thanks

 

You need new Mercon V in any event.
Fil with 4 qts, start the engine, run thru the gears with your foot on the brake, then check the level with the motor running.
If it shows on the dip stick, let the engine run to warm the fluid then check the level again. Add fluid till it reaches to the bottom of the cross-hatch area.
After a road run to get the fluid up to it's normal operating temp fill to near the top of the crosshatch area and you done.
