Adjusting the bands on a 3 speed auto trans

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

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

Is this adjustment for a 1997 3 speed auto also?

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 had a th350 tranny that slipped like crazy. After a band adjustment the tranny worked like new. A lot of transmissions get rebuild when they only need a band adjustment.

I would only recommend adjusting the tranny if it feels like something is wrong.
