    Experiencing higher than usual RPM's in 4th gear on level road. Appears the torque converter is not locking up. Is there an electronic A/T controller going bad? I've had problems in the past with Honda automatics. They were notorious for failed electronic controllers. I read some other blogs stating the torque converter seal may be bad, causing higher RPM's. My fuel mileage is significantly decreased. Any info would be greatly appreciated!!!

    There have been a few cases of bad torque converters, trans computer is under pass seat, if it gets wet it can also be damaged.
