I am not sure where to post this, but I have a 1991 Roadmaster Wagon with the amazing TBI 305...

My transmission died, so I swapped in a spare 4l60 (non E). This trans was from a 4.3 blazer 2wd, and has a 40 tooth vss reluctor.

My VSSB or DRAC module is looking for the 4x output from the original gear driven (700r4) vss...

So do I need a drac module from a truck, or can I change the jumpers around on the module I have?

Thanks Guys!
