Range selector mode indicator was not displaying correctly while in D. If I moved the shift lever slightly to N the D would indicate otherwise, while in drive it would not be indicated. All other positions were lit and displaying OK. Research pointed to a bad TRS aka Neutral Safety Switch.
Another thing that pointed to the TRS while in drive would intermittently not shift properly to OD or while at 50+ MPH inadvertently bump out of OD at which point I would shift to N and back to D to recover overdrive.
Took it to a trans shop that previously worked on it to diagnose with a DRB-II. The tech was moving the shift lever from P to 1st through the range and back again to observe what I was experiencing. He was not being gentle about it. My first thought was, "take it easy".. I never shifted like he was doing, and in hindsight, I should have said something. He thought there was a little bit of "play" in the lever. At 476,000 miles, probably so after all, it's not a new truck. His thoughts were also a bad TRS.
Shortly after I drove away all backlit indications went dark including no audible or visual turn signal blinking, odometer, fuel level, trouble indications. Turn signals work, just no audible or visual display. I called the trans shop shortly afterwards leaving a message with the owner. I never heard back.
I changed the TRS in hopes that it would solve the issues. It shifts and runs OK now however, I have no backlit display showing as I should. The rest of the console gauges display OK i.e. fuel level, Temp, Oil, Battery.
