The transmission shifts harshly, or it may stay in first gear. The harsh shifting is more noticeable on the 1-2 and 2-3 upshifts under light throttle. It is not affected by operating temperature. The MIL may be on with DTC P0730 or P0715 stored. PROBABLE CAUSE Contamination of the linear solenoid and its associated passages inside the transmission, or a broken spring internal to the transmission. Flush the transmission with Genuine Honda ATF-Z1, then replace the linear solenoid. If shift feel is not affected, replace the transmission.
