What gear were you in and what were the rpms.

 

Well, what gear were you in?
Most people try to shift an automatic like a manual, and that just hurts the performance.
Just leave it in drive and step on the go-go pedal

 

D4

 

Next time I would recommend D3. D4 is basically your Overdrive and the car will automatically upshift.
Say in D3

 

but isnt it bad to drive around in D3??

 

No

You should use D3 for you normal every day driving, up to 50-55mph. So basically if you know you're gonna get on the highway, keep it in D3 until you reach around that speed and then upshift into D4 for highway speeds. This is all in your owners manual.

 

really? i never really read it to find that out. isnt it a lil quicker that way also?

 

kord: that will hurt your mileage tremendously. Mine shifts into 4th at a little over 35 mph! if it wasnt optimal for the engine to shift into 4th, it wouldnt.

 

I agree with you Fango: ive been 100mph in D3 and my rpms were around 5200 or so
and ive also been 110mph in D4 around 3500 rpms...Isnt it true the more rpms your pushing the more fuel your burning ? and mine shifts into 4th around 35 also!

 

but since then, I've hit 137 in D4 ..... even before it was dyno tuned.
