I'm going to change my trans fluid and filter and want to adjust the bands while I'm in there. Anyone have a good link they can post up on how to do it properly ? I tried search and didn't find much. 2001 TJ 3 speed automatic. Thanks :cheers2:

There was an easy tutorial even in the Haynes manual, but if I recall, the tricky part was having the correct in-lbs torque wrench. I'll try to find my older Haynes manual later and post up. Same procedure I used on my older '97 TJ

From the FSM:
FRONT BAND ADJUSTMENT
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. 179).
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 5/16 socket.
(4) Back off front band adjusting screw 2-1/2 turns
for the 30RH and 2-1/4 turns for the 32RH.
(5) Hold adjuster screw in position and tighten
locknut to 41 N·m (30 ft. lbs.) torque.
(6) Lower vehicle.
REAR BAND ADJUSTMENT
The transmission oil pan must be removed for
access to the rear band adjusting screw.
(1) Raise vehicle.
(2) Remove transmission oil pan and drain fluid.
(3) Loosen band adjusting screw locknut 5-6 turns.
Be sure adjusting screw turns freely in lever.
(4) Tighten adjusting screw to 5 N·m (41 in. lbs.)
for the 30RH and 8 N·m (72 in. lbs.) torque for the
32RH (Fig. 181).
(5) Back off adjusting screw 7 turns for the 30RH
and 4 turns for the 32RH.
(6) Hold adjusting screw in place and tighten locknut
to 34 N·m (25 ft. lbs.) torque.
(7) Position new gasket on oil pan and install pan
on transmission. Tighten pan bolts to 17 N·m (13 ft.
lbs.) torque.
(8) Lower vehicle and refill transmission with
Mopart ATF Plus 3, Type 7176, fluid.

IMHO....this is the most useless item on the planet.
I have never seen or heard of an automatic tranny that needed the bands adjusted (other than at overhaul). I have also never heard of an auto that was having a problem that band adjustment fixed long term (but I'm only 50 years old).
I really think you are more likely to screw something up than to fix and/or improve the life of your transmission by making this adjustment.
You may have noted that on many new cars there is not even a recommendation to change auto trans fluid as a maintenance item for the entire life of the vehicle. If your tranny is working good the main thing that will kill it is contamination (dirt or water) or heat.

I adjusted the bands and I didn't notice any difference. That being said, it's easy to do and doesn't take much time so I will do it again after the next 30,000 miles. Maybe the point is to prevent you from having symptoms if you never have them adjusted? Don't know, don't care - it's free and it takes 5 minutes.
