Help identifying my transmission - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This one has me stumped big time.
The transmission that came in my '67 appears to be a TH350. HOWEVER, it has only two speeds. The trans pan has the angled corner notch and 13 bolts indicating that it's a TH350 which is a three speed. Thought maybe it a TH250 but that's also a three speed from what I found. I may at a loss as to what it is. Any help in identifying it would be greatly appreciated.

Defective TH350 that fails to engage one of its three gear ratios?

Is there a transmission listed on the SPID?

Here's a link with info.

Sounds like there issue with the transmission not shifting.
