2014 Seneca 37TS not downshifting

[LTUcrew]

Hi there,

Any know why out of the blue, my 14 TS stopped downshifting when I let off the gas? It will start downshifting when I drop the selector into 3 but when in D it stopped.

Previously it would do it almost instantly towing or not.

Exhaust brake turned on? My 2014 will "coast" with the EB off.

Once you come to a stop, does it start off in first and upshift okay? No trouble codes or warning lights evident?

I don’t have or have not found an exhaust brake switch anywhere. It shifts fine from a stop.

I complained to Freightliner about the exact same thing on my 22-37TS. They put it on the computer and test drove the diesel out of it and found nothing wrong. I can say that if you press the mode button it will down shift more like what you are used to. I attached a pic of the engine brake switch.

His rig is a 2014 as is mine. Lever shifter and no "Mode" button.

Exhaust brake switch directly under shifter.
