NOTICE: Whenever a transmission has been disassembled to install new parts, the transmission fluid cooler tubes must be cleaned and backflushed using a suitable torque converter/fluid cooler cleaner. A new Oil-To-Air (OTA) transmission fluid cooler must also be installed. When internal wear or damage has occurred in the transmission, metal particles, clutch plate material or band material may have been carried into the torque converter and fluid cooler. These contaminants are a major cause of recurring transmission concerns and must be removed from the system before the transmission is put back into service. NOTE: After the transmission is removed for a major overhaul, it is important to completely clean all transmission components, including torque converter, cooler inlet tube, main control valve body, clutches and all coasting booster valve shuttle balls after any transmission service that generates contamination. These contaminants are a major cause for recurring transmission concerns and must be removed from the system before the transmission is returned to service. The cleaning of foreign material from the direct clutch check ball is often omitted. This omission can lead to a repeat servicing of the transmission. A new Oil-To-Air (OTA) transmission fluid cooler must be installed under the following condition. For additional information, refer to Section 307-02. Evidence of broken transmission components or transmission fluid contamination found due to the following transmission or converter failure modes: Major metallic failure Multiple clutches or clutch plate failure Sufficient component wear which results in metallic contamination 1. Disconnect the battery ground cable. For additional information, refer to Section 414-01. 2. WARNING: Before servicing a vehicle equipped with a fire suppression system, depower the system by following the procedure in Section 419-03. Failure to follow the instructions may result in serious personal injury. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02. 3. NOTE: Only if transmission disassembly or replacement is required, drain the transmission fluid. For additional information, refer to Fluid Pan, Gasket and Filter in this section. Drain the transmission fluid. Loosen the transmission fluid pan bolts and allow the transmission fluid to drain. After transmission fluid has drained remove the bolts and the pan and drain the remaining transmission fluid that is in the pan. 4. Install the transmission fluid pan and the old transmission fluid pan gasket. 1. Position the transmission fluid pan gasket. 2. Position the transmission fluid pan. 5. NOTE: To maintain the initial driveshaft balance, mark the rear driveshaft yoke and the axle pinion flange so they can be installed in their original positions. Mark the rear driveshaft yoke and the axle pinion flange and remove the 4 bolts.

Transmission Fluid Refill NOTICE: This procedure contains the air purge steps required to purge air from the cooling system. This procedure is NOT intended for use with the Transmission Fluid Level Check. NOTICE: The vehicle should not be driven if the fluid level is low as internal failure could result. NOTICE: The fluid fill plug is located near the exhaust system. The exhaust will be extremely hot during this procedure. NOTICE: The use of any other transmission fluid than specified, can result in the transmission failing to operate in a normal manner or transmission failure. NOTE: If the transmission starts to slip, shifts slowly or shows signs of fluid leaking, the fluid level should be checked. NOTE: Here is an overview of the Transmission Fluid Drain and Refill procedure. Adding 3.3L (3.5 qt) of clean automatic transmission fluid to the transmission is an initial fill enabling you to start the engine. The cold level range shown in the procedure allows the vehicle to be driven. The vehicle should be driven to allow the transmission fluid temperature to reach 85ºC-88ºC (185ºF-190ºF) in order to purge the air from the transmission cooling system. Fill the transmission fluid to the fill range on the fluid level indicator at the normal operating range 80ºC-85ºC (175ºF-185ºF). 1. NOTE: The transmission will need 3.3L (3.5 qt) of clean automatic transmission fluid added to the transmission as an initial fill if: the transmission has been overhauled. a new mechatronic assembly has been installed. the transmission fluid pan or fluid filter have been removed. Using the special tool, add 3.3L (3.5 qt) of clean automatic transmission fluid to the transmission through the fluid fill hole. For additional information, refer to Adding Additional Transmission Fluid in this procedure. 2. Check the transmission fluid level cold. 1. The vehicle is safe to drive if the transmission fluid is in the cold level range 32°C-43°C (90° F-11 0° F). Using the scan tool and the engine running, place the transmission selector lever in each gear position and hold approximately 5 seconds. Place the transmission selector lever in PARK, with the engine at idle (600-750 rpm).

Before road testing, be sure the fluid level and control cable adjustments have been checked and adjusted if necessary. Verify that diagnostic trouble codes have been resolved.Observe engine performance during the road test. A poorly tuned engine will not allow accurate analysis of transmission operation. Operate the transmission in all gear ranges. Check for shift variations and engine flare, which indicates slippage. Note if shifts are harsh, spongy, delayed, early, or if part throttle downshifts are sensitive. Slippage indicated by engine flare, usually means clutch, band or overrunning clutch problems. If the condition is advanced, an overhaul will be necessary to restore normal operation. A slipping clutch or band can often be determined by comparing which internal units are applied in the various gear ranges. The Clutch and Band Application chart provides a basis for analyzing road test results. Note that the rear clutch is applied in all forward ranges (D, 2, 1). The transmission overrunning clutch is applied in first gear (D, 2 and 1 ranges) only. The rear band is applied in 1 and R range only. Note that the overdrive clutch is applied only in fourth gear and the overdrive direct clutch and overrunning clutch are applied in all ranges except fourth gear. For example: If slippage occurs in first gear in D and 2 range but not in 1 range, the transmission overrunning clutch is faulty. Similarly, if slippage occurs in any two forward gears, the rear clutch is slipping. Applying the same method of analysis, note that the front and rear clutches are applied simultaneously only in D range third and fourth gear. If the transmission slips in third gear, either the front clutch or the rear clutch is slipping. If the transmission slips in fourth gear but not in third gear, the overdrive clutch is slipping. By selecting another gear, which does not use these clutches, the slipping unit can be determined. For example, if the transmission also slips in Reverse, the front clutch is slipping. If the transmission does not slip in Reverse, the rear clutch is slipping.
