A few weeks ago I saw a thread about adjusting the bands in an auto trans. I can't find the post now. I think it was written by "JakeBrake" can some one repost it.

Thanks

All I can say is based on the information given to me by several rebuilders is this, Do Not adjust the bands unless it is slipping. The bands are thin pices of metal and once you adjust them to much they wear out and break. Then you have to rebuild your trans because the bands broke.

 

Some say adjust every 30,000 miles, others say don't until it slips. I adjusted mine because the fluid was burnt and was slipping. To adjust bands is real easy. You'll have the 48re so I'm not sure if it is the same as the 47re. But with the 47re there are to band, a front and a rear. You can adjust the front with out dropping the pan, the rear the pan needs to come off. Pretty much it is torque the adjuster down to 72"lbs and back off a certain amount depending on year and trans and then lock down.
