How many people here do anything with the $EE mask ('94-'95 LT1 apps)?

We're using an 8051 to control a Caddy 500/4L80E combo in our 1990 
Suburban and we have a couple of questions on things that are stumping us.

How does one set the torque convertor to lock in manual 2nd?

The VSS originally fed a DRAC which fed the speedo and goofy 1 channel 
rear-only ABS. Since the 8051 has the capability to output almost any 
multiple of the VSS frequency, we dumped the DRAC and are running the 
speedo and ABS off a PCM output, which mostly works... except that the 
ABS is constantly flashing the brake warning light with its trouble code 
indicating that it's not getting a good VSS signal. What's different 
between the DRAC output and the 8051 speedo output and how do we get the 
ABS to work with the speedo output?
