Automatic Transmission Servicing - 46RE & 47RE: Other Dodge Durango I

Transfer Case

Check transfer case fluid level when performing other underhood services. Under normal or severe service conditions, change transfer case fluid at specified interval. See TRANSFER CASE SERVICE INTERVALS table. Severe service conditions are conditions such as long periods of engine idling, trailer towing, extreme temperatures, off-highway operation, snow removal, or operating in dusty conditions.

TRANSFER CASE SERVICE INTERVALS

1. Drive vehicle until engine and transmission are at normal operating temperature. Park vehicle on level surface. Apply parking brake.
2. With engine idling, shift transmission through all gear ranges, ending in Neutral. Check fluid level. Fluid level should be between MIN and MAX area on dipstick with transmission fluid temperature at 180°F (82°C). Transmission fluid temperature can be checked on models equipped with 4-speed transmissions using scan tool. Follow scan tool manufacturers instructions. Add appropriate type of fluid as necessary. (Scheme 168)- (Scheme 170) RECOMMENDED FLUIDS. DO NOT overfill.

Scheme 168

Scheme 169

Scheme 170

Park vehicle on level surface. Remove transfer case fill plug from rear of transfer case. Fluid level should be even with bottom of fill hole. Add appropriate type of fluid as necessary. See RECOMMENDED FLUIDS . Install and tighten transfer case fill plug to specification. See TORQUE SPECIFICATIONS .

On 2000 models, manufacturer recommends Mopar(R) ATF+3, Type 7176 fluid. On 2001 models, manufacturer recommends Mopar(R) ATF+4, Type 9602 fluid for all transfer cases except NV247. On NV247, manufacturer recommends Mopar(R) transfer case lubricant (05016796).

1. Ensure vehicle is parked on level surface. Remove transfer case drain plug. Transfer case drain plug is located on right rear corner of transfer case. Allow fluid to drain.
2. Reinstall transfer case drain plug and tighten to specification. See TORQUE SPECIFICATIONS . Remove transfer case fill plug. Transfer case fill plug is located on rear of transfer case, below identification tag.
3. Fill transfer case with appropriate fluid until level is even with bottom of fill hole. See RECOMMENDED FLUIDS . Install and tighten transfer case fill plug to specification. See TORQUE SPECIFICATIONS .

OIL COOLER FLOW CHECK

1. With transmission filled to proper fluid level, disconnect oil cooler return line from transmission (rear cooler line). (Scheme 171) Place container under oil cooler return line.
2. Apply parking brake. Start engine and allow to idle. Place gearshift lever in Neutral. Check fluid flow from oil cooler return line.
3. If fluid flow is consistent and takes 20 seconds or less to obtain one quart, oil pump volume and oil cooler flow are okay. If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, disconnect oil cooler inlet line. Refill transmission to proper level and recheck flow.
4. If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, check line pressure. For 2000 models, see HYDRAULIC PRESSURE TESTS under PERFORMANCE TESTS in appropriate OVERHAUL article. For 2001 models, see HYDRAULIC PRESSURE TESTS under PERFORMANCE TESTS in appropriate DIAGNOSIS article. If fluid flow is consistent and takes 20 seconds or less to obtain one quart, replace oil cooler. Reconnect oil cooler lines. Fill transmission with appropriate ATF. See CHECKING FLUID LEVELS.

ON-VEHICLE REPAIRS

Note. Various components may be serviced without transaxle/transmission removal. For servicing of these components, see appropriate component under ADJUSTMENTS and/or REMOVAL & INSTALLATION . For additional information on testing electrical components, see appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.

Grand Cherokee

1. Shift transmission into Park. Remove gearshift lever bezel and floor console as necessary for access to shift cable adjustment screw. (Scheme 174) Loosen shift cable adjustment screw. (Scheme 175) Adjustment screw is located in slot at end of shift cable.
2. Raise and support vehicle. Unsnap shift cable eyelet from transmission control lever. Move control lever fully rearward. Ensure transmission is in Park by attempting to rotate driveshaft. Snap cable eyelet onto transmission control lever. Lower vehicle.
3. Tighten shift cable adjustment screw to 62 INCH lbs. (7 N.m). Verify adjustment by attempting to start engine in Park and Neutral. Adjustment is okay if engine starts in Park and Neutral, and does not start in any other gear position. Install gearshift lever bezel and floor console.
