Good evening, if you have the VIN of the vehicle please let me know so that I can find out what trans you have and what engine size. The band adjustment procedure is the same for all of them except for the number of turns to back off, Here is the procedure:
The front (kickdown) band adjusting screw is located on the left side of the transmission case above the manual valve and throttle valve levers.
CAUTION: If Adapter C-3705 is needed to reach the adjusting screw , tighten the screw to only 5 N·m (47-50 in. lbs.) torque.
The transmission oil pan must be removed for access to the rear band adjusting screw.
Once you get me the VIN, I will get back with the trans size you have which is either a 46RE or a 47RE, most likely the 47RE but lets be sure first.
5.8 L turbo diesel
...and the winner is 47RE so follow the directions for this trans when performing the adjustment.
