The Stovebolt Site Forums The Shop Area Driveline Questions about the '46 3-spd

Seems like I saw some literature once upon a time that says that it's supposed to be synchronized, is this true? On my dad's old truck double clutching second gear is a must. It's not required on 3rd gear but you kinda have to feel it in there. If it is supposed to have synchro's, can they still be had?

Dad says it's always been that way, but I think he also told me that back in the day his dad used parts from 12 different transmissions to make one working one.

Also what about the rear seal? The transmission has a tendency to get dry, the fluid seems to leak out and go down the torque tube. If it's just a little dry you can park it on a downhill incline and the fluid will run back into the trans and it'll be better for a while. How hard is i this to replace.

Finally, what is the correct weight and type of fluid?

I just finished rebuilding my 41 3speed which should be the same as your 46. Second and third are syhchronized, I got some of my parts out of a newer transmission 58-59, cluster gear and reverse idler were the same, the newer trans had a four lug synchro, I just cut it down to 2 and it looks the same as the old one now. I think I used the sliding clutch out of the newer trans also but had to machine down the sliding gear because it was too wide. I haven't put it back into the truck yet. I had to take some time to find new or good used parts such as the input gear and the main shaft but I found them.

I can't help you with the other questions, others will come along and help with that. Dave
