Spent some time today troubleshooting the LED Shift Select Display module. Lately I had been noticing that the LED display seemed to dim over time making the letters/numbers illegible. The current circuit board is a Stone Bennett #LA2-12. Thanks to the guys at BCS I was directed to United Transmission Exchange in San Bernardino, CA for a replacement board (Part #21438). During my discussion with United the gentleman suggested that I do a little troubleshooting first and make sure that all the grounding wires were properly connected and making good contact. He stated that most of the time that is the problem with the LED display going dim and did not want to sell me a new unit only to have the same problem once installed. He even offered to send me the complete wiring diagram for the unit so that I could check everything out. Hats off to the parts guys at BCS and United Transmission Exchange for their superb customer service.
