i did a search and read some thread that might be related and im thinking DRL problem. i put a towel over the sensor that's on my dash and i doubt it made any changes so here's my problem.

when the sun is out and hot outside the mileage of the vehicle would NOT show and im having shifting problems. its an automatic. i could drive and the car would rev,speed up, drive normal, act like it's in netural for a moment.

but once the speedo is working and the mileage is shows the car drive perfect like nothing is wrong with it. in another thread i figure it might be the ground wire located under the dash. i look around and i dont see any ground point near the brake pedal.
