3 torqueflite questions...

middle wire is ground, one is od, one is lockup google around or check your manual- how do you plan on controlling your od/ lockup do you have the engines computer- that would be easy
yes a-500 uses more oil and only use atf 4+ no dexron and especially no trick **** or type F or you will be buying a new converter and plugging up your cooler- which will destroy complete geartrain in trans and od
run big 1/2 lines to your big 1/2 in-1/2in out cooler - you can find good coolers in Ford trucks/ vans
early to 94 A 500 used 22 degree helix on planataries and insufficient oil will fry the thrust washers- which, when they fail, OD goes boom
on early trans kick out of od going up big hills or towing
later trans used 15 degrees- you can install later parts but shaft has to be correct years as the planateries as size changes by a small amount

early gears will not slide on late shaft but late gears are sloppy fit on early shaft and will strip the hubs and make more small pieces
which engine 318?
