Most GL5 gear oils are buffered and don't have issues with manual transmissions. The LSD additives will usually not assist the shift so avoid gear oils equipped with LSD additive.
Redline MT90, Torco RTF, Amsoil MTG, BG, Eneos, Idemitsu, Synlube, Motul, Ford, GM, ..... have gear oils for your manual trannie.
Toyota also recently developed a lifetime fill LV MTF. With Nissan, Kia, Hyundai, GM,....and numerous other automakers switching manuals to thinner 75w85's in place of 80w90 gear oils, I am going to guess that LV MTF is an 85wt, or possible thinner gear oil. A 75w85 GL4 might also be an option.
