The newly running White Whale III (01 5.9 2wd auto) has a problem, the PCM is not activating the OD/ converter lock.

Anyone have good ideas on a scanner/ dongle/ software that will diagnose transmission problems reasonable?
My 92 had/has an overdrive or lockup issue and has been traced to the VSS or TPS not giving a steady signal. I found 2 weak grounds and 1 loose wire in the VSS switch pin plug. my overdrive is now solid.
