    picked up an old Gibson tractor, i know its o-t but old man Gibson used whatever parts he could get and man, thats traditional. So it has an old chevy trans in it, i found a bowtie on a shift fork. its not synchronized so pre '32? cant find any pics or drawings that match it. im missing a shift fork and parts of the shifter tower and need to find some.

    One car that Chevy made in huge numbers was the model 490. No idea if that is it, but try a google image seach for chevy or chevrolet 490 transmission or maybe even engine.

    Try some different keywords, you may find a lubrication chart that will show the motor and trans from above.

    I have a 1948 Gibson Model D Garden Tractor also. However, I've been told the trans and rear end are MOPAR (Plymouth). That's definitely a Chevrolet Bow Tie on the fork however (?). The rear is definitely an 8 3/4 on mine. You can do an internet search for Gibson tractors. They were made in Seattle, and later, in Colorado. I've seen some with a more "tractor-like" rear end, with open axles. Tiller steering, dual manual brakes, a drop hitch, and front blade.Mine is going to be used for yard art. They come up for sale around here pretty often, anywhere between $200-$1200. Seen them on E-Bay also. Butch/56sedandelivery.

    There's a current post on here, "Need help ID'ing an engine or two". One of the pics is a 216 Chevrolet block with a very similar trans bolted to it. It's probably from a truck as it has a foot starter. Butch/56sedandelivery.

    its close, but not the same. on mine, the shaft for the forks sits on top of the case and are held down by the cover. thanks for the help. ill try to clean it up and look for any casting numbers.

  11. looks like thy turned it a 1/4 turn, a lot of the old chev stuff will interchange, i stuck some 1947 parts in a 1954 trans, not quite original but they worked

    i was thinking the same thing, but i dont beleive it is. drain plug on bottom, bellhousing bolt pattern, etc. reseach shows they used mopar, jeep, ford, and chev transmissions in these. maybe the shift tower is chev and the trans. is not? the case has six bolt holes while the shift tower has 4. they line up.
