The oil level control is located on the electrohydraulic unit (4) and consists of the float (5) which is integrated into the electrohydraulic unit. The float is positioned to plug the opening (6) between the oil gallery (2) and gearset chamber (1) so that the rotating gearsets do not splash about in oil as the oil level rises. The oil level control reduces power loss and prevents oil from being thrown out of the transmission housing at high oil temperatures. See Fig. 182. OPERATION FLUID LEVEL CONTROL With low oil levels, the lubricating oil which flows constantly out of the gearset, flows back to oil gallery (2) though the opening (6) If the oil level rises, the oil presses the float (5) against the housing opening (6). The float (5) therefore separates the oil gallery (2) from the gearset chamber (1). The lubricating oil which continues to flow out of the gearsets is thrown against the housing wall, incorporated by the rotating parts and flows back into the oil gallery (2) through the upper opening (arrow). See Fig. 183. DIAGNOSIS AND TESTING CAUSES OF BURNT FLUID Burnt, discolored fluid is a result of overheating which has three primary causes. Internal clutch slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal failure. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is usually the result of a faulty or improperly installed drainback valve, a damaged oil cooler, or severe restrictions in the coolers and lines caused by debris or kinked lines. Heavy duty operation with a vehicle not properly equipped for this type of operation.

CAUTION: The torque converter must be replaced if a transmission failure resulted in large amounts of metal or fiber contamination in the fluid. The torque converter is a hydraulic device that couples the engine crankshaft to the transmission. The torque converter consists of an outer shell with an internal turbine (1), a stator (3), an overrunning clutch, an impeller (2), and an electronically applied converter clutch. The converter clutch provides reduced engine speed and greater fuel economy when engaged. Clutch engagement also provides reduced transmission fluid temperatures. The converter clutch engages in third through fifth gears. The torque converter hub drives the transmission oil (fluid) pump. See Fig. 267. A turbine damper (6) has been added for some applications to help improve vehicle noise, vibration, and harshness (NVH) characteristics. The torque converter is a sealed, welded unit that is not repairable and is serviced as an assembly. IMPELLER

1. Position a floor jack under the right side lower suspension arm. 2. Raise the wheel and allow the tire to lightly contact the floor (vehicle weight relieved from the tire). 3. Mount a dial indicator (Special Tool C3339 or equivalent) solidly on the upper suspension arm (Fig. 1 ). Fig. 1: Right Side View Of Suspension (Wheel/Tire Removed For Clarity) 4. Position the dial indicator plunger against the back side of the steering knuckle boss for the upper ball joint (Fig. 1 ). 5. Zero the dial indicator while pulling outward on the top of the tire. 6. While an assistant watches the dial indicator gauge, grasp the top of the tire and push inward. Record the dial indicator reading observed from the full outward to full inward position. 7. Repeat Step #1 through Step #6 on the left side upper ball joint. When both the left and the right upper ball joints have been inspected, proceed to Step #8. 8. Based on the results recorded in Step #6: a. If the lateral movement on both upper ball joints is less than 0.060 in. (1.52 mm), no further action is required. Remove the dial indicator, lower the wheel and return the vehicle to the owner. b. If the lateral movement on either of the upper ball joints is greater than 0.060 in. (1.52 mm), replace both upper ball joints as described in the Repair Procedure.

Anti-Theft Systems – Dakota & Durango DESCRIPTION VEHICLE THEFT SECURITY SYSTEM Vehicle Theft Security System (VTSS) provides perimeter protection against unauthorized use or tampering by monitoring vehicle’s doors, ignition system and liftgate (Durango). VTSS flashes headlights and sounds horn if any door, hood or liftgate (Durango) is opened without using valid key or Remote Keyless Entry (RKE) system. VTSS is controlled by Central Timer Module (CTM). CTM is located behind left side kick panel. VTSS is also equipped with a power-up mode. If battery is disconnected or loses power while VTSS is armed, VTSS system remains armed when power is restored. A tamper alert signal is sounded on vehicle entry if VTSS was triggered while away from vehicle. Horn will sound 3 times, alerting owner VTSS was triggered. SENTRY KEY IMMOBILIZER SYSTEM If vehicle is equipped with optional Sentry Key Immobilizer System (SKIS), ignition key will have a Gray molded rubber cap. Models not equipped with optional SKIS will have a Black molded rubber cap on the head of the ignition key. SKIS consists of the Sentry Key Immobilizer Module (SKIM), sentry transponder keys, SECURITY indicator LED and Powertrain Control Module (PCM). SKIM is located under steering column shrouds, near ignition lock cylinder. Transponder is located in ignition key. See Fig. 1 . If an invalid ignition key is used, SKIM will send invalid signal to PCM, causing engine to start and run for 2 seconds, then stop. If vehicle is started with invalid keys 6 times in a row, vehicle will shut down until correct key is used.
