Just purchased my gs and I would like to know what is the best position to drive the car in?
D4/ or 4/ or D3 and will the power switch on will that eventually wear out the tranny. The car has 145,000 on it. Thanks
I understand d3 is for around town and will drive at higher rpm what is the fatest u can go in d3

 

Just leave it in D. ECT PWR shifts at higher RPMs with firmer shifts, it won't necessarily wear out the transmission any faster. I only use the 4,3,2, and L settings for engine braking when necessary (e.g. down a hill), limiting it to a specific gear in normal driving will have an adverse effect on your fuel economy and could increase wear to the driveline components.

 

 

I leave mine in D with power on. And only use e-shift buttons for downhill engine braking as well.

 

Thanks for your help

 

Keeping the car in PWR mode is supposedly better for your transmission as the firmer shifts produce less wear and heat.

 

I keep in D with POWER off. I get good gas mileage.

 

POWER when you need it, NORMAL when you don't SNOW for well, obvious reasons.

and doesn't driving it in 4 defeat the over drive gear and causes premature wear on the tranny parts?

 

thanks everyone
