Don't know what kind of manuals you drove but every manual I know of either takes gear lube (75w-90, 75w-140, etc), or many mazda/ford manual trannys actually take ATF.

I just changed mine to Amsoil as well, after I got my car up on ramps and saw the large fill and drain plugs plainly labled "see owners manual before refilling"... it was a simple job with the beer bong funnel to fill her up...
