NOTE: Perform the Coast Down Adaptations first. The Transmission Temperature must be greater than 60°C 2. Drive the vehicle until the transmission temperature is in the specified range. 3. Perform 4 to 5 coast downs from 5th to 4th gear and then 4th to 3rd gear. NOTE: For Upshift adaptation, the Transmission temperature must be greater than 60°C (140°F) and less 4. From a stop, moderately accelerate the vehicle and obtain all forward gear ranges while keeping the Engine RPM below 1800 RPM. Repeat this procedure 4 to 5 times. 5. Obtaining 5th gear may be difficult at 1800 RPM. Allow the transmission to shift into 5th gear at a higher RPM then lower the RPM to 1800 and perform manual shifts between 4th and 5th gears using the shift lever. 6. The TCM will store the adaptives every 10 minutes. After completion of the adaptation procedure make sure the vehicle stays running for at least 10 minutes. 7. It is possible to manually store the adaptives under the 10 minute time frame using the scan tool Store Adaptives procedure. QUICK LEARN - 4.7L/5.7L VEHICLES The quick learn procedure requires the use of the scan tool. This program allows the electronic transmission system to recalibrate itself. This will provide the proper transmission • Transmission Assembly Replacement • Transmission Control Module Replacement • Solenoid Pack Replacement • Clutch Plate and/or Seal Replacement • Valve Body Replacement or Recondition To perform the Quick Learn Procedure, the following conditions must be met: • The brakes must be applied • The engine speed must be above 500 rpm • The throttle angle (TPS) must be less than 3 degrees • The shift lever position must stay in PARK until prompted to shift to overdrive • The shift lever position must stay in overdrive after the Shift to Overdrive prompt until the scan tool indicates • The calculated oil temperature must be above 60° and below 200° DRIVE LEARN - 4.7L/5.7L VEHICLES When a transmission is repaired and a Quick Learn procedure has been performed on the Transmission Control NOTE: It is not necessary to perform the complete Drive Learn procedure every time the TCM is Quick LEARN A SMOOTH 1ST NEUTRAL TO DRIVE SHIFT Perform this procedure only if the complaint is for a delayed or harsh shift the first time the transmission is put into NOTE: The transmission oil temperature must be between 80 - 110°F (27 - 43°C). 1. Start the engine only when the engine and ignition have been off for at least ten (10) minutes. 8E - 290 ELECTRONIC CONTROL MODULES - SERVICE INFORMATION WK |
