The Stovebolt Site Forums The Shop Area Engine Shop Manual Trans Fluid;

I've got a '59 apache 36 w/ manual 4-speed that i just cleaned and sealed up(looks great)and need to replace fluid....my service manual states 5 1/2 pints SAE 90W and i can't seem to locate this @ my local parts store. Is there a "new" or substitute oil? Unfortunately the "kids" @ local parts store have no idea what i'm talking about or care!! How about a synthetic? Thanks for all the info, you gear heads out there have helped me immensely!

Theres all kinds of gear oil on the market today 90 to 125 wt.and synthetics stick with a good brand name like moble or pensoil and make sure it's for gear boxs it will say on the label anything from 75-90 multi grade to 90 wt will do.
