This old transmission sat in our old shed back home in Ohio from at least the late 1950s until about 2000 when I brought it to my garage and stored it. I don’t remember if or where Dad said he got it. I am finally getting around to lightening my load so I pulled this out, cleaned the dirt and gunk off it, and gave it a light coat of penetrating oil. I was only slightly surprised to find that there was still some lube inside…not the full amount but enough to protect the works. I drained the case (and noted a faint gear lube smell---perhaps it dissipated over 80 years or maybe gear lube back then didn’t have the same distinctive odor??) but I did not rinse it clean…there is still a light coating on the gears.

From my research I believe that this 3 speed transmission was for 1937 thru 1939 Chevrolet passenger cars. The casting numbers on the case’s side are “590822 GM2 F297”. I believe that the last four digits are the date code and signify that it was made on June 29, 1937. There is what I believe to be a serial number rather crudely hand stamped into the bottom rear machined face on the case. Some of the stampings are weak but believe it reads “SD378II” (those last 2 digits are the capital letter “I” not the number “1”). Please see the close up photos of all those numbers. And please verify that those numbers fit your application; I am not an expert or a pro.

This transmission is being sold for rebuild. How much of a rebuild, I do not know. In the very least, it will need new gaskets and seals. All of the gears look in very good shape…no chipped or missing teeth…I don’t even see any pitting. There were no metal shavings or pieces laying in the case. All of the gears spin freely and smoothly. The only potential issue I can spot with the “guts” is that the front main bearing on the shaft to the clutch probably needs to be replaced…if you wobble that shaft there is maybe 1/16” movement at the very front end with the play coming at the bearing area.

The case itself is in very good shape with no leaks or cracks…with one notable exception: over a decade ago I moved it in my garage and managed to clip the case with a pipe I was trying to get at. The result was that I broke off about ½ of one of the four mounting flanges to the clutch’s bell housing. (Please see the photos—I have highlighted the break.) However, I have the broken off piece and will sell it with the trans…perhaps you can weld it back on. If not, there is still a surface area that a bolt can tighten against especially with a washer. Otherwise, the case is in very good condition…the fill and drain plugs are in good shape with full, clean threads.

The universal joint looks like it is in good shape but you might want to replace it while it is so accessible. The U-joint’s ball housing is in good shape although you will want to replace the front and rear seals. Also, one of the four attaching bolts for the housing is missing…and has been for a long time. However, it is not broken off in the hole…those threads seem fine.

The shift lever is solid and the only damage to it is some pitting in the metal of the shaft. There is no knob on the shifter. Also, one of the four bolts the hold the shift lever in place needs to have the threads cleaned up…I dinged them up a little and no longer have a tap and die set. (I started to remove the bolts before I realized that there’s a strong spring involved…when I tried to reinstall them, I damaged the threads on the end of one bolt…I stopped before I stripped the threads badly…just “chasing the threads” should do the trick…or you can get another bolt).

The old speedometer cable has been cut off but the speedo’s gearing looks good.

We live just a few miles north of Richmond, IL and the Wisconsin border.

Hope you can use it. Thanks for reading.
