Identifying a Fluid Drive transmission

[Pep48]

When I bought my 1948 coupe, there was no spare tire in the trunk, but there was a (spare?) transmission and also a bell housing and what looks like a torque converter. So, I'm wondering if this is a fluid drive set up?

 

How can I identify it? I'm not at my shop today, but I'll try to post some pics tomorrow, and look for casting or  ID plate numbers.

 

Did the Fluid Drive use the same transmission as the manual trans?

Thanks!

First welcome, 2nd, you are still under the become a new member section of the site  So go to browse forums select p15 d24 and start a new thread. Third, take quik trip to allpar.com search transmissions, look under the fluid drive section, there might be info there can use to help ID.  If not you can read up on the units, and their operation and care and feeding.  Hope you have an answersoon. Typically there was an m5 used from 41 till 46 ish and the m6 which took over till 49 ish till fully auto trans was introduced in 55.
