lightly on throttle. watch the youtube video a few posts up it explains it all

 

So I've finally gotten around to testing this out and mine does exactly what yours does. in MM rpms will just drop and not really hold the gear, but once I put it in D and drive for a few seconds cruising, it'll feel like it shifts into another gear and then it is locked into gear.

I wish MM would fully lock the gear.

 

^ according to the manual they are suppose to do the same thing

So its odd, that it will do something different in manual mode.

This means that the general knowledge of Manual mode with this Transmissions still has many unknowns.

 

I wonder if there's a way to change that.

I feel really unhappy now knowing that our transmission can lock gear a lot more but MM just really doesn't, or at least in the low rpms. Personally I like the feel of it being locked rather than stepping on it and it having to rev up to catch up to the motor, not smooth at all.

 

^ Yep def not smooth at all. In D it does not do this.

Is there a benefit of the transmission doing slip-lock while cruising?

I wonder if coasting in 5th turns off the fuel injectors, if it was locked like in D it would be right? Since its not locked its most likely not beneficial for MPG, right?

City wise you can short shift. But if your on the highway D is the way to go it seems.

 

dude what song is that in your video?

I tried this last night on the interstate ~75-80
Mine acts exactly the same in [D] and [5]
Revs don't drop.

Guess that's another difference between the 03-04 and the 04.5+

BTW, mine is an 03.0... so idk if that matters or not

 

Anytime you let off the gas and coast, the injectors are not firing. Whether in gear or not. Save for idle.

 

^^^ not sure what you mean Dave... injectors are of course running fuel (regardless of throttle)... I guess that's what "save for idle" meant?... but traveling 80mph and releasing theottlebisnt exactly idle...

 

Nope, fuel is not going to the injectors when you let off the throttle. That's why coasting in neutral gets worse MPGs than coasting in gear which requires absolutely no fuel. When coasting in gear, the engine is still technically running as the plugs are still firing. Not until you apply throttle do the fuel injectors come back on line. I said "save for idle" because obviously at slow slow speeds fuel does need to go to the engine to keep it from stalling. It's called coasting fuel shut-off. All modern day fuel injected cars do this. My Outback's navigation system indicates infinite MPGs while coasting in gear.

 

But Since the car is in slip lock, and the RPM's dip down. Its not really coasting in Gear while in MM.

While in Drive it is 100% coasting in gear.

If lets say my speed is 35 and I am in 4th, It will drop down to idle and bounce off it like a bouncing ball, so that the engine does not stall. But at higher speeds the drop in RPM is not that low so you dont see the bouncing effect.

 

This is a true fact!

 

How is there combustion with spark, air and no fuel?... in fact there wouldn't be air either withought the initial combustion... so how do you propose the engine does not stall out when there is no fuel being added?... granted, the duration is much shorter - but its there nonetheless
