Abstract: Methods and systems are provided for diagnosing a stuck Active Transmission Warmup (ATWU) valve. In one example, a method for an ATWU valve monitoring routine of a vehicle comprises determining a temperature difference between an engine coolant temperature (ECT) and a transmission fluid temperature (TFT) over a duration before the ATWU valve is commanded from a closed position to an open position or from the open position to the closed position comparing a rate of change of the TFT before and after the ATWU valve is commanded to the open position or the closed position; and indicating a stuck ATWU valve based on at least one of the temperature difference, the TFT rate of change comparison, or a combination thereof, based on a calibration parameter.

Abstract: Systems and methods for diagnosing operation of a transmission warm-up valve are presented. In one example, the transmission warm-up valve is commanded to an open position and an estimated transmission fluid temperature is compared to an actual transmission fluid temperature to determine whether or not the transmission warm-up valve is operating as commanded.

Abstract: The invention discloses a pharmaceutical composition comprising phenylephrine in a sustained-release formulation alone or in combination with another active such as an antihistamine, an analgesic, an antipyretic or a non-steroidal anti-inflammatory agent or a mixture of two or more other actives. In a preferred embodiment, the composition comprises a solid dosage form with hydroxypropyl methylcellulose and carboxymethyl cellulose sodium as a matrix for sustained release of phenylephrine. Phenylephrine is released over a prolonged period of time by the solid dosage form essentially independent of pH.
