Think it's a holdover from old IEWL limitation of 3200 for blksize.  
TRANSMIT can do PDS or sequential.
If PDS it does the special IEBCOPY unload to 80/3120 FB documented in TSO  
Command Ref. Controlling member is IKJTSOxx. Yes Virginia there is a  
VIO(unit).

never  cared to look at what TRANSMIT allocated. I just tried and found 
that TRANSMIT  overrides the block size with 3120, when the data set already 
existed (and  uses this when it allocates the data set).
