What tranny is this

[70redvert]

I pulled the motor and transmisssion out of my '70 Cutlass convertible
Can someone decode it for me. On the drivers side of the casing there is B3 in about 1" and half letter size, below that is the #s 6260110 and below that is the # 3. Does this help anyone?

Thanks for your time,

Greg

On the passenger side should be a rectangular tag riveted to the case and it will have two large letters on it on each end of the tag; OG or OW etc. and on the bottom will be the serial number of the trans, on the drivers side should have a number stamped just above the pan lip on the case corresponding to your vin if it is the original trans...

Let's start with, is this an automatic or a stick?

I'll assume it's an automatic, in which case this should help:
