Automatic Transmission Band Adjustment:

The front band controls the 2nd gear cluster. The rear band controls the 3rd gear cluster and reverse. For a 2-3 shift, the transmission shifts back to 1st gear with the front band while the rear band engages 3rd gear. If the front band does not release the 2nd gear clutches before the third gear clutches engage, the transmission binds, which shortens the life of the transmission clutches. If the front band releases too early in the shift, the engine will overspeed (sounds and feels like a slip) during the 2-3 shift.

1. Loosen band adjusting screw locknut. Then back locknut off 3-5 turns. Be sure adjusting screw turns freely in case. Apply lubricant to screw
threads if necessary. The front band adjuster is on the outside of the transmission and the locknut requires a 3/4″ wrench.

2. Using Inch Pound Torque Wrench C-3380-A, a 3-in. extension and appropriate Torx™ socket (T-40), tighten adjusting screw to 72 in-lb. CAUTION: If Adapter C-3705 (from SPX Miller) is needed to reach the adjusting screw, tighten the screw to only 47-50 in. lbs. torque.

3. Back off adjusting screw the number of turns listed below for your transmission.

4. Hold adjusting screw in place and tighten lock-nut to:

41 N·m (30 ft. lbs.) for the front band
34 N·m (25 ft. lbs.) for the rear band
The adjustment screw inside the case is a square head bolt. You will need a 1/4 square head socket to fit your torque wrench. (this may also take a 1/4″ or 5/32″ six point socket)

    I had problems with my 06 Dodge diesel downshifting from second to first way too much. Under the least amout of pressure it would shift back into first… I was ready to order a new tranny off the internet for $3200 until i found this website about how to adjust the bands. Since i was having problems with the lower gears i only adjusted the low bands and my problem went away. It shifted better than it has in years. I then went ahead and took off the pan and adjusted the higher gear bands. This has saved me uncounted $$$ Thanks for this help… also this isn’t a job only for a seasoned mechanic… a novice back yard mechanic can do this with ease. The website says check the band adjustments every 3 yrs or 30K miles….. at 165K I figured it was past due….
    Thanks again
