Hey guys, thanks for welcoming me to the site! I have a 1947 3/4 ton chevy pu. The 4speed has been removed and it has a 3speed in its place. Anyway the 3speed started giving me some problems and jumping out of 2nd gear. I cant seem to find anyone that will commit to rebuilding it, they all give me the runaround. The casting # is 591195. I looked that up an it says its a commercial 3speed made from 41-47. I would love to have it rebuilt, but it looks like Im gonna have to go with a different tranny. Can anyone tell me what the easiest tranny swap would be without alot of FAB work under the truck???
My next question is if i put a 373 rearend in this truck will I have enough of a first gear or should i shoot for a 410 rearend. The truck still has the original 473 rearend in it and top speed is around 45-50. I would love to get the old truck up around 60 just to keep from getting run over out there.
Well thanks for reading the post and any help or advice will be greatly, greatly appreciated!
Thanks again and have a great day!
