Keep checking in gentlemen, our guro is traveling but will check in soon. Please provide as much details as you can. Multimedia, WELCOME!!

Multimedia check that the keypad has power when the key is turned on, the hot lead from the on/off start switch.

Cowboy Check the plugins on the shifter pad are not coming loose and on the trans itself. there appears to be a communication problem.

believe its the 3000 shifter butons on a dutch star . fluid levels are fine new filter . but the lights shouldnt effect that should it

Just to have the info, I'd first run a stall test. Make sure the engine is up to power and the trans isn't slipping or having torque converter problems.

Also, check the connector at the base of the selector. Look for loose terminals, etc.

If the light comes on, there should be a trouble code. What's that code(s)?

Hi
I have a MD 3060 ECM and my selector switch is blank and i have tried a different ECM and also a different selector and still no good at the moment the truck wont start and the (Check Transmission Light is on ) anyone have the same problem how do i resolve the issues.

Greetings all from China.

Sounds like the trans TCM or the shifter aren't getting power. Make sure the power is connected, and the TCM sees the ignition signal. It'll take a vehicle wiring diagram and some patience. Good luck.

Hi AllisonMan, have a 05 FL M2 with 3000 TRV with Transynd. Intermittant engine flare occurs at 35mph shift (2nd to 3rd gear?). Seems to occur more so when at operating temp. It was suggested by a tech at Freightliner could be solenoid connection. What does your experience tell you with this type of problem.
