Consumer Description

LOSS OF POWER (INTERMITTENT) WHILE DRIVING AT A CONSTANT LOWER SPEED AND OCCASIONALLY DURING ACCELERATION. ADDITIONALLY, WHEN GOING UP A HILL THE AUTOMATIC TRANSMISSION DROPS IN GEARS WHICH SIGNIFICANTLY INCREASES RPMS THEN ONCE ON FLAT ROAD THE VEHICLE TAKES SOME TIME TO CHANGE GEARS. IF I HIT THE GAS PEDAL ONCE AT THE TOP OF THE HILL, THE RPMS GO PAST 3.5. SO I WAIT UNTIL THE CAR SWITCHES GEARS BEFORE PRESSING THE GAS PEDAL.
