19 - Steering / Gear / TIE ROD, Steering / Diagnosis and Testing DIAGNOSIS AND TESTING OUTER TIE ROD 1. Raise and support the vehicle (Refer to 04 - Vehicle Quick Reference/Hoisting/Standard Procedure) . 2. Remove the front wheels. 3. Install two standard wheel mounting nuts, ﬂat side to rotor, diagonally opposite to each on the rotor. 4. Attach a magnetic dial indicator (2) to the inside or outside of the brake rotor, then align the dial indicator's contact pointer (1) with the direction of the stud axis and touch the outer tie rod. 5. Zero the dial indicator (3). NOTE: When checking free-play, DO NOT rotate the tie rod. Just because a tie rod rotates easily does not mean that it is necessarily faulty. Using more than light hand pressure will result in a false reading. 6. Grasp the outer tie rod near the ball stud and attempt to move the tie rod straight up and down using light hand pressure (less than 10 lbs. of force). 7. Measure and record any tie rod free-play movement. 8. Remove the magnetic dial indicator. 9. Remove the standard wheel mounting nuts from the two studs. If the free-play in the tie rod exceeds 0.05 mm (.002 in.), replace the outer tie rod (Refer to 19 - Steering/Gear/TIE ROD, Steering/Removal and Installation) . If the free-play is less than 0.05 mm (.002 in.) at the outer tie rod check the inner tie rod for free-play. INNER TIE ROD 1. Raise and support the vehicle (Refer to 04 - Vehicle Quick Reference/Hoisting/Standard Procedure) . 2. Grasp the inner tie rod near the steering gear bellows and attempt to move the tie rod straight up and down. If any free-play is felt, replace the inner tie rod end (Refer to 19 - Steering/Gear/TIE ROD, Steering/Removal and Installation) . 3. Remove the support and lower the vehicle.

INSTALLATION Follow the removal procedure in reverse for general reassembly of the components on the vehicle. The steps listed below are calling out specific procedures that should be followed during installation. Thread the outer tie rod end onto the inner tie rod, using the same number of threads as when removed. If a new tie rod end is to be installed, be certain the boot is properly lubricated. Clean all old grease and debris from the boot with a clean cloth. While holding the ball stud with a wrench, tighten the tie rod end to knuckle nut to the proper (Torque Specifications) . Tighten the tie rod jam nut to the proper (Torque Specifications) .

This fluid is NOT compatible with ATF+4 or any other current FCA US LLC transmission fluid. For specifics about this unique fluid see FLUIDS, LUBRICANTS AND GENUINE PARTS. The transmission case is a single-piece unit. The starter pocket, cooler line fittings, and manual park release lever are located on the driver's side of the case. The transmission wire harness connector and oil fill plug are located on the passenger side of the case. The two-wheel drive model uses a flanged output shaft

connection. The four-wheel drive model uses a sealed, externally-splined output shaft to form a dry connection between the adapter plate and the transfer case. Identification In the area of location (A) there are two barcodes and their corresponding alphanumeric codes. The top code identifies the COMPONENT TRACKING NUMBER. The bottom code identifies the PART NUMBER. OPERATION The 8HP75 is an electronic eight-speed automatic transmission. The Transmission Control Module Assembly (TCMA), which is integrated into the valve body, provides fully synchronized clutch-to-clutch shifting through four planetary gear sets. The TCMA includes a mounting plate that holds the Transmission Control Module (TCM) and a molded wiring harness for connection to various transmission sensors and solenoids. The valve body assembly contains all the sensors and solenoids required for operation, completely inside the transmission. Eight speeds allow the engine to maintain its optimal rpm range, increasing fuel economy and performance. Transmission control is performed by the TCM based on hard-wired and Controller Area Network (CAN ) bus signals from sensors and modules. The TCM receives driveability data from the Powertrain Control Module (PCM) and other modules over the CAN-Chassis (CAN-C) bus. The TCM also receives shift lever position information from the Electronic Shift Module (ESM) over a dedicated transmission CAN bus. The TCM processes this input data and controls operation of the torque converter clutch, park lock system, solenoid valves, and pressure regulating valve. The input and output speed sensors are Hall-effect sensors that measure shaft rotational speed. The input speed sensor is located at the top, near the center, of the of the TCMA and reads input shaft speed from the magnetic ring on the P2 carrier. The output speed sensor is located at the back of the TCMA and reads output shaft speed from the P4 carrier. GEAR RATIO 1st 5.000 2nd 3.200 3rd 2.143 4th 1.720 5th 1.313 6th 1.00 7th 0.823 8th 0.640 Reverse 3.478 FILTER SERVICE The 8HP75 has a conventional fluid sump design, however, the transmission oil filter is integrated into the transmission oil pan resulting in a lower profile for improved vehicle packaging. The transmission oil pan gasket is reusable providing it is not damaged during removal. If the gasket is damaged inspect the transmission oil pan for damage. Replace the transmission oil pan gasket or the transmission oil pan and gasket as an assembly. FLUID CHECK AND FILL A transmission fluid fill tube and indicator are not provided. All work is performed under the vehicle while raised on a hoist. In the event of a transmission shift quality concern, a fluid leak, or in conjunction with a transmission repair, the transmission fluid level must be validated and topped off as necessary. The procedure involves the use of a scan tool to monitor transmission fluid temperature. Specific service procedures are necessary to check and fill the transmission with fluid (Refer to 21 - Transmission and Transfer Case/Automatic/FLUID and FILTER/Standard Procedure) . Epicyclic Gear Sets

EP (1, 2, 3, 4) epicyclic gear train The 8 forward gears and reverse are implemented by connecting four single-arm epicyclic gear trains. The two front gear trains have a common sun gear, while the power is always output through the fourth epicyclic gear train planet carrier. Engagement Elements There are five engagement elements divided as follows: Brakes A B Clutches C D E Multiple-disc clutches C, D and E transmit the engine torque to the epicyclic gear train, while brakes A and B offload the engine torque to the transmission housing. The engagement elements are hydraulically closed. The fluid pressure compresses the disc pack to engage the clutch. When the hydraulic pressure decreases, the diaphragm spring pushes the piston into its rest position. The engagement elements serve to engage the gears under load without interrupting the traction force. For each gear, three engagement elements are always closed while two engagement elements will always remain open. Each open engagement element creates drag torque which allows an increase in transmission efficiency. Brakes

1 Brake B Piston 2 B1 Chamber 3 Return Spring 4 Brake B 5 Brake A 6 Return Spring Brake B has a spring pack to return the piston into position. Brake A has a diaphragm return spring. Clutches 1 Piston 2 Pressure chamber 3 Hydraulic compensation chamber 4 Diaphragm 5 Diaphragm spring The dynamic pressure of clutches C, D and E is compensated.
