Drive 3
 

When Im in the city I keep my v6 in drive 3. I never go above 4 and half grand. Will this have any negative effect on my car? I hate it when Im in drive 4 and it shifts back and forth.

drive 3 limits your car to maximum of 3rd gear.
if you push 45-50 in town you'll get excessive rpms.
but if your just mopeding around at 30-40 drive 3 is fine.
excessive rpms btw wont harm your car in that speed range it will just burn extra gas.
>>Later>>

Why not just put it in D4 and let your tranny decide which gear is best?!

i dunno 'bout the v6 but the i4 really likes rpms over 3500. they work best there.

For acceleration, sure..

But when cruising, why waste gas for nothing??

Agreed. If you're just cruisin, leave it in D4.

my point exactly.

maybe he likes the roar of the engine ;) who knows ?

craziness needs no explanation... so i wont try to explain.
