After a busy week at work I have finally been able to get back to this.

After decoder factory reset
CV 29 = 54

I rebuilt the JMRI roster entry and selected the Tsunami Bachman Sound Value and have all controls back.

Thanks for the help!

Here is what I am reading using decoder pro.

CV 29 = 38, CV 7 = 82 no CV 25, 2,5,6

I reset and selected the Tsunami Diesel Bachmann Sound Value as the decoder and still get no throttle control with JMRI.

Thank you for the tip.  I will take a look.

Does anyone know the actual decoder model that is installed in the Rio Grande™ #5336 (Large Flying Grande) - SD45 - DCC Sound Value?  JMRI reads it as several different options.  There are two options in SoundTraxx; DSD diesel and DSX diesel.  I chose the latter and using the JMRI throttle can activate functions but can not control speed forwards or backwards.  Command station works fine for throttle.  If anyone has suggestions please let me know.  Thank you.
