SYMPTOM *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.* PARTS INFORMATION Linear Solenoid Assembly: P/N 28250-P4R-315, H/C 5317219 Drain Bolt Washer: P/N 90471-PX4-000, H/C 3300936 REQUIRED MATERIALS Genuine Honda ATF-Z1: P/N 08200-9001, H/C 6512628 Civic and 2WD CR-V – 11.6 quarts required 4WD CR-V – 12.4 quarts required

To prevent system contamination, whenever the evaporator core is replaced, also replace the receiver/drier. NOTE: The evaporator core is not separately serviceable, it is serviced only with the evaporator core housing assembly. NOTE: If an evaporator core leak is suspected, the evaporator core must be leak tested before it is removed from the vehicle; see—– 07-10 A/C EVAPORATOR / CONDENSER CORE ONVEHICLE LEAK TEST . 1. Remove the evaporator core housing. See 07-11 EVAPORATOR CORE HOUSING REMOVAL / INSTALLATION . 2. Transfer the components from the old evaporator core housing to the new evaporator core housing. 3. Install the evaporator core housing. See 07-11 EVAPORATOR CORE HOUSING REMOVAL / INSTALLATION . 1. Disconnect the blower motor and blower motor resistor electrical connectors. 2. Disconnect the heater hoses. a. Using suitable tools, clamp-off the heater hoses. b. Release the clamps and disconnect the heater hoses. 1. Detach the pin-type retainer and position aside the windshield washer hose. 2. Disconnect the vacuum supply hose near the evaporator core housing. 3. Disconnect the condenser to evaporator line spring lock coupling from the evaporator core inlet. See 07-10 SPRING LOCK COUPLING . • Discard the O-ring seals. NOTE: The following step is performed at the lower passenger side dash panel, inside the passenger compartment.Disconnect the vacuum hose connector and remove the nut.
