6F24 Automatic Transmission - Service Information: Overview Dodge Dart PF

Scheme 5

Before the completion of the transaxle assembly procedure and before installing the valve body, an air test should be performed to determine the condition of the seals in the clutch and brake pistons. Using a rubber tip air nozzle, apply regulated 482 kPa (70 psi) shop air into the ports shown for each clutch or brake.

DESCRIPTION AND INSPECTION

The valve body is the device that controls the hydraulic power flow to the clutches and brakes within the 6F24 Automatic Transaxle. The valve body is equipped with on-off and variable force solenoids the are electrically controlled by the PCM. If the transaxle passes an air pressure test and is relatively clean, the transaxle should be OK and the valve body is most likely at fault. All of the valve body internal components must be a able to travel freely within there bores and cylinders. Any dirt or debris within the valve body can cause a valve or piston to bind and fail to function. The valve body valves are somewhat self cleaning. The leading edges of the valve chambers are ground sharply to cut through soft debris and allows the valve to function. The strainers and screen in the valve body are designed to filter out dirt and debris as the fluid circulates through the hydraulic passages. If a valve or piston is deeply scratched and can be felt with a fingernail the valve body or transaxle must be replaced depending on parts availability.

1. Remove the engine cover/air cleaner from the vehicle. For 2.0L, refer to «AIR CLEANER, REMOVAL»(ref-646216-S32691632802014072800000) . For 2.4L, refer to «AIR CLEANER, REMOVAL»(ref-646217-S18981223602014072800000) .
2. Drain the fluid from the transaxle. Refer to «FLUID, STANDARD PROCEDURES»(ref-646221-S28379567152014072800000) .
3. Using common pliers (3), compress the hose spring clamp (2) and slide it down the vent hose (1) away from the nipple adaptor.
4. Pull the vent hose end (1) off of the nipple adaptor (2).
5. Position suitable drain pan under the valve body cover to catch fluid that may spill as the cover is removed.
6. Remove bolts holding the valve body cover (2) to the transaxle (1).
7. Separate the valve body cover (1) from the transaxle (2).
8. Remove bolt holding fluid temperature sensor (1) to the valve body (2).
9. Pull temperature sensor (1) straight out of the port in the valve body (2).
10. Remove bolts holding the solenoid valve connector (2) to the valve body (1).
11. Starting at the bottom solenoid valve, using a suitable prying tool, pry outward at each solenoid (2) until the connector (3) is disengaged.
12. Remove the screw holding the manual shaft detent spring (1) to the valve body (2).
13. Separate the detent spring (2) from the valve body (1).
14. Remove bolts, 7 short (1) and 1 long (2) bolts, holding the valve body to the transaxle. The manual valve is loose after the valve body is removed and may fall out during removal.
15. Separate the valve body (2) from the transaxle (1).
16. Remove the two seals from the transfer ports in transaxle housing.
