FMCSA and Coasting

He's talking about AMT transmissions in trucks the past ten years or so are programmed to kick the transmission into neutral when you crest a grade and coast down hills to save fuel. If you tap the brakes or accelerator it kicks it back into gear. Or hold your foot on the accelerator to keep it from kicking out.

 

You better believe they have their bases covered on this. But also you as the driver need to know when to take control and keep it in gear.

 

I don’t think I could get used to that.

 

Yeah it sucks. Loses about 4-5mph off your set cruise speed when it does it, then rolls and coasts slowly back up to that set speed. It's strange if you've never been in a truck that does it. Like a loss of control feel to it. But really it isn't. It can be programmed out.

 

I never did. I keep those transmissions in manual except for flat ground

 

Georgia Overdrive is what l have heard it called

 

Yep, Georgia Overdrive. From back when trucks topped out about 55-60 mph, throw it in Georgia and get 80 plus mph going down a hill.
