Re: Identifying a 39 Tranny
the serial number stamped on the case will identify the year made.

Re: Identifying a 39 Tranny
You have to look inside, the serial number will show what years the case was originally used for, but the inside gears can still be most any year

Re: Identifying a 39 Tranny
first you are looking for a 37 up case with the number 78-xxxx embossed in the rear of the case. second pull the top cover off and the 2/3 gear shift fork will measure 3" thus the trans will have the best synchronizer. third the serial number stamped into the top of the case will tell you the year

Re: Identifying a 39 Tranny
Some '39 transmissions used the older synchronizer and gears. You can not use only the serial number to determine if a '39 transmission has the later gears. The only sure way is to remove the top and look inside.

Re: Identifying a 39 Tranny
Take the shift tower off, and look at the syncro where the shift forks enter. If its in the middle, like a sliced bagel, its the old style, and if the fork goes in way off center its the 39 & up gearset.

Re: Identifying a 39 Tranny
Also, it should be mentioned here that if you have the "78" case, and he proper shift fork, later side shift gears will fit right in. You don't need '39 gears. It makes the parts situation a bit easier.

So, as the tubman is saying, the gear set is the SAME from some 1939s thru 1948. Lots of '40-'48 transmissions still out there for parts. DD |
