Reprogram the TCM using the applicable PAK file. 2. Follow the procedure shown below (and outlined in Service Bulletin 16-80-11R) for flushing the transmission fluid and performing the Dynamic Check Mode. NOTE: TCM memory must be cleared prior to performing the following procedures. Transmission Flush Procedure 1.) Remove the ATF drain plug and drain ATF. 2.) Remove the oil pan and thoroughly clean (including the magnet) then reinstall following the steps in the applicable Service Manual. 3.) Refill ATF to correct level. Dynamic Check Mode 1.) Raise vehicle on lift. CAUTION: Be sure to keep the tires 30cm (12 inches) or more off the ground as the vehicle will vibrate on the lift during the following procedure. 2.) Depress the brake pedal and start the engine (keep pressing the brake pedal until Step 5) then press VDC OFF switch to deactivate VDC. 3.) Move the transmission select lever to the ”D” position and increase the engine speed to 1,000 rpm by pressing the accelerator pedal. Hold engine at 1000 rpm for two minutes. 4.) Release accelerator pedal, then move the select lever to the “N” position for two seconds, then back into the “D” position for two seconds, repeat (N to D) five times. The following steps need to be performed in Manual mode using the paddle shift switches. 5.) Move the select lever to the “M” position (Manual mode). Shift up to 2nd using the paddle shift switch (keep in 2nd for two seconds) then shift down to 1st using the paddle shift switch (keep in 1st for two seconds) repeat (2nd to 1st) five times. 6.) Release the brake pedal then accelerate gently to 40 mph by shifting into 3rd using the paddle shift switch. 7.) Keep at 40 mph, then shift up to 4th gear for two seconds then shift down to 3rd gear for two seconds; repeat (4th to 3rd) five times. 8.) Accelerate gently to 50 mph by shifting into 5th gear using the paddle shift switch. 9.) Keep at 50 mph, then shift down to 4th gear for five seconds then shift into 5th gear for five seconds; repeat (4th to 5th) five times. 10.) Decrease the vehicle speed by easing off the accelerator pedal (do not apply the brake pedal). Keep in each gear for five seconds (4th gear, 5 sec., approximate speed 40 mph) -> (3rd gear, 5 sec., approximate speed 30 mph) -> (2nd gear, 5 sec., approximate speed 20 mph) – > (1st, 5 sec., approximate speed 10 mph). 11.) Depress the brake pedal to stop the tires from rotating completely. Move the select lever to the “P” position (this completes the Dynamic check mode). 12.) Check for trouble code(s) using the SSMIII. If codes are stored, clear TCM memory again. The Dynamic Check Mode may store trouble codes due to variation of the wheel speeds. Bulletin Number: 16-86-12; Date: 12/11/12 Page 3 3.
