Transfer Case
Under normal or severe service conditions, change transfer case fluid at 30,000-mile or 24-month intervals.
- Drive vehicle until engine and transmission are at normal operating temperature. Park vehicle on level surface. Apply parking brake.
- 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). (Scheme 51) Transmission fluid temperature can be checked on models equipped with 4-speed transmissions using scan tool. Follow scan tool manufacturer's instructions. Add appropriate type of fluid as necessary. See «RECOMMENDED FLUID»(ref-170037-S21989413222004122800000). DO NOT overfill.
Scheme 51
Remove fill plug. Check fluid level. If fluid is not level with bottom of fill hole, add appropriate fluid. See RECOMMENDED FLUID .
Manufacturer recommends Mopar® ATF+4, Type 9602 fluid.
Note. Transmission and torque converter capacities are approximate. Always determine fluid level with dipstick. See TRANSMISSION FLUID CAPACITIES table.
| Application | (1) Refill - Qts. (L) | Dry Fill - Qts. (L) |
|---|---|---|
| 46RE, 48RE, 45RFE & 545RFE | 4.0 (3.8) | (2) 9.5 (9.1) |
| (1) Refill capacity indicates initial amount of fluid to add during fluid and filter change. Add necessary amount of fluid to bring level between MIN/MAX marks on dipstick after transmission fluid has reached normal operating temperature. (2) Quantity may vary by type of oil cooler and oil cooler lines. | ||

TRANSFER CASE FLUID CAPACITIES
- Remove drain plug (if applicable) and drain fluid into appropriate receptacle. Loosen oil pan bolts. Tap pan to break loose, and allow fluid to drain. Remove oil pan and filter.
- Install new filter on bottom of valve body. Tighten filter retaining screws to specification. See «TORQUE SPECIFICATIONS»(ref-170037-S11552221272004122800000) . Install new "O" ring on fluid pickup pipe, if necessary. Clean oil pan, and install using new gasket. Tighten drain plug (if applicable).
- Fill transmission with appropriate fluid. See «RECOMMENDED FLUID»(ref-170037-S21989413222004122800000) . Ensure vehicle is parked on level surface. Apply parking brake. Start engine and allow it to idle for a few minutes. Move gearshift lever through all gear ranges.
- Return gearshift lever to "NEUTRAL". Add fluid up to MIN mark on dipstick. Recheck fluid level when transmission reaches normal operating temperature. Fluid should be between MIN and MAX marks on dipstick. Do not overfill transmission.
Remove drain plug from transfer case. Remove fill plug for easier draining. With fluid fully drained, reinstall drain plug. Fill transfer case with appropriate fluid. See RECOMMENDED FLUID . Install fill plug. Tighten drain and fill plugs to specification. See TORQUE SPECIFICATIONS .
OIL COOLER FLOW CHECK
- With transmission filled to proper fluid level, disconnect oil cooler return line from transmission. Place container under oil cooler return line.
- Add one extra quart of ATF to transmission. Apply parking brake. Start engine and allow it to idle. Place transmission in Neutral. Check fluid flow from oil cooler return line.
- If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, replace radiator or external oil cooler. Reconnect oil cooler return line. Fill transmission to proper fluid level with ATF. See «CHECKING FLUID LEVEL»(ref-170037-S22516546192004122800000) .
ON-VEHICLE REPAIRS
Note. Various components may be serviced without transaxle/transmission removal. For servicing of those components, see appropriate component under ADJUSTMENTS and/or REMOVAL & INSTALLATION . For additional information on testing electrical components, see appropriate DIAGNOSIS article.
GEARSHIFT CABLE
Check adjustment by starting the engine in "PARK" and "NEUTRAL". Adjustment is correct if the engine starts only in these positions. Adjustment is incorrect if the engine starts in one but not both positions. If the engine starts in any position other than "PARK" or "NEUTRAL", or if the engine will not start at all, the transmission range sensor may be faulty.
- Shift transmission into PARK.
- Release cable adjuster lock tab (underneath the steering column) to unlock cable. (Scheme 52)
- Raise vehicle.
- Disengage the cable eyelet from the transmission manual shift lever.
- Verify transmission shift lever is in "PARK" detent by moving lever fully rearward. Last rearward detent is PARK position.
- Verify positive engagement of transmission park lock by attempting to rotate propeller shaft. Shaft will not rotate when park lock is engaged.
- Snap the cable eyelet onto the transmission manual shift lever.
- Lower vehicle.
- Lock shift cable by pressing cable adjuster lock tab upward until it snaps into place.
- Check engine starting. Engine should start only in "PARK" and "NEUTRAL".
