The service manual I have only shows the 47re transmission, are the adjustment and diagrams for the 47 and 48 the same? The manual is for 00to 06 trucks, that is way I ask. Thanks

 

This is from my 06 manual:


ADJUSTMENT - BANDS
FRONT BAND
The front (kickdown) band adjusting screw is
located on the left side of the transmission case
above the manual valve and throttle valve levers.
(1) Raise vehicle.
(2) Loosen band adjusting screw locknut (Fig. 74).
Then back locknut off 3-5 turns. Be sure adjusting
screw turns freely in case. Apply lubricant to screw
threads if necessary.
(3) Tighten band adjusting screw to 8 N•m (72 in.
lbs.) torque with Inch Pound Torque Wrench
C-3380-A, a 3-in. extension and an appropriate
Torx™ socket.

adjusting screw, tighten the screw to only 5 N•m
(47-50 in. lbs.) torque.
(4) Back off front band adjusting screw 1-3/4 turns.
(5) Hold adjuster screw in position and tighten
locknut to 41 N•m (30 ft. lbs.) torque.
(6) Lower vehicle.

The Rear Band is inside:

access to the rear band adjusting screw.
