Transmission Question

In general, yes. The case may be beefier but the guts are the same. And the rear mount mounting bolts may have self locking nuts instead of castle nuts. So unless you are looking to be judged, yes.
 
Essentially the same transmission, except for the shape of the shifter handle. The '39 is a graceful "swan shape", where-as the pick-up leans rearward, then is straight to the top. DD
 
truck trans has 29 tooth cluster gear where the car has 28 tooth, essentially a lower gear for starting heavier loads. also works really well for higher ratio rear axles such as 3:54. 2nd gear is also a little lower, my experience running one was you seem to run out of gear in second, can't get very far and gets there quick

Hmmm, well I definitely have a 39 shifter in my 41 truck.

The ****** may be 39 also.

Here's a comparison of shifter levers.

Try to look at the flat pad at the top of the housing where it bolts to the engine. That is where the serial number is stamped. If you can post that number (it will most-likely start with an I8-*******), we can decipher the model year from that. See pic below for location. DD

Did the '40 Pickup have the '39 swan neck type shift lever then? My 40 does- but I wonder if it was swapped out at some point in it's life.

A couple of points to realize here before answering your question.......1/2 ton pick-ups were technically referred to as "Commercial", and NOT "Trucks". The term "Truck" was used by Ford when a heavier type of truck was being talked about.

Soooo......what most of us regularly refer to as a 1/2 ton pick-up usually came with a 3-speed top-shifter trans just like a '39, except with the differently-shaped straight shift lever. These light-duty 1/2-ton pick-ups could be ordered with that "granny" 4-speed, and when ordered as such, it's noted in the serial number by adding a "BB" prefix.

Didn't the 1/2 ton truck transmissions frequently have open-drive main shafts? It seems that a lot of the open-drive conversions I've used over the years - all came from trucks.

Anybody know?
 
^^ Yes, but the OP specifically stated 41 ford half ton, which had the closed drive.

Mart.
