Re: Problem with AT 4f27e
I think I actually understood that!
What's your current mileage? Also, if mileage is above 60K, and you haven't done a transmission fluid change, do so! that might clean up bad shifting. You can also replace the TPS (throttle position sensor) and/or IAC( idle air controller) both located around the throttle body and will run $30-40 each but should smooth out the idle and any RPM changes. If a tune up (with new spark plugs) hasn't been done in the last 50K, get it done. Quick acceleration runs will burn up plugs faster as quick acceleration isn't considered to be 'normal' operation and you should abide by the 'severe service' schedule in your owners manual for service requirements.
