only 1985 miles on it.
last week started noticing my transmission was acting funny, and of course with my warranty, took it in to find that the Transmission Range Sensor failed. 5 days later i finally got my car back with a new one installed....
but you know how you can feel even the slightest change in your vehicles performance, or that little knock you know wasnt there the other day... you can just tell when your car isnt acting right (if you pay attention to those things.. most guys do, but thats not a knock to you ladies.)
anyway, i think that my rpm's are just too high during normal driving. im at 20k rpm at 40mph in normal acceleration. It just seems too high. My idle rpm is at 7500 and i dont recall it being that hight before my sensor failed.
now, i also read on some forum in a far away land, that another customer had the same issue, and his MPG decreased by 10-15%...
is there a way to find the detailed specs on this card to find the normal range of rpms to mph and idle speed rpms?
what im thinking is that with the sensor that failed, something else may have been screwed in the process, and they cant detect it, and my transmission is going to drive in high gear all the time, thus killing my MPG which is the reason i bought this damn car in the first place...
anyone got anything i can run with?
Or ask them to show you any other Focus on their sales lot that idles that high.
7500 RPM is so far out of range, that I almost suspect an additional problem -- a bad RPM sensor or engine-control module.
Look into "lemon laws" in your area as well, in case you can't get it fixed and need to return the car for a refund (or threaten to do so).

but that still seems high.
and at 40 MPH i meant to say 2k... i must have added an extra 10k everywhere...sorry...
are my numbers still too high? i feel they are... any my gas guage is showing it... that needle is moving way faster than it did.
But with cars these days, it could be something as dumb as an oxygen sensor. Who knows. I suspect you'll have to diagnose this by calling the mechanic folks again.
There are fora out there for most models with great info and helpful enthusiasts. Since I can't link there, Google "ford focus forum" I'll bet they've got an answer.
As to automatic gearboxes shifting sooner or later it depends a bit on "style" of the driver and settings. But the logic in most common gearboxes is very primitive: basically output RPM is measured and engine vacuum (together with a kick-down from the throttle and position of the lever). That input is "calculated" into shift points using what is basically a "mechanical computer" in the form of valves, gaskets and a hydraulic maze.
There of course have been some improvements to make it slightly smarter and to allow to have more gears than a handful, but the basic system is still the same.
Far smarter "automatic" gearboxes exist (e.g. Volkswagen's DSG gearbox: these are actually *dual* regular manual gearboxes used in a sequential manner under computer control) but they're not typically used in mass market products by the ailing US automakers.
then, reset my milage tracker counter with a full tank of gas. drive normally to and from work and do some calculations...
13 Gal / Miles counted... hopefully will give me a good estimate.
they rate at 35 hwy and 28ish city...if i even come close to that ill be satisfied...
if i see something like 15-20... i might lose my cool over at their service shop...
1900 miles and this happens? not on my watch.
