Ram Automatic Transmission Band Adjust
Visit Geno's Garage
for Truck accessories.
Recommended Intervals for Band Adjust, Fluid Change, Filter Change:
24,000 miles or 24 months, whichever comes first
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.

From: Devin Olson <>
If I had the gosh-darned Torque wrench (with a 5/16 Square socket) ahead of time, it would have been a whole lot less frustrating.
Nut Bolt Sizes:
Rear band adjustment (inside the tranny) locknut = 9/16".
Rear band adjustment screw = 1/4" hex.
Front band adjustment (outside of the tranny on the driver's side) locknut = 3/4".
Front band adjustment screw = 5/16" SQUARE male.

Ok here is the scoop for you guys.
If you can use a torque wrench you and adjust the bands on your tranny. The bands should be adjusted every fluid change. For severe service vehicles that is every 12k or normal i believe is 30k.
There are 2 adjustment screws - one on the outside of the tranny and one on the inside (you get to it by taking off the pan). The basic procedure is the same for both but torque specs are a little diff for each. If you guys want to know specifics email me back an i will get them. I am at work and doing this from memory. Here are the steps for each:
1. Loosen the adjustment screw 5 - 6 turns and make sure it spins freely in the hole.
2. Tighten the adjustment screw to 8nm.
3. Back off adjustment screw exactly 2 turns
4. Tighten lock nut to torque spec (diff for each bolt)
That's it you do that for each screw and you are good
Basically if you bands are not adjusted correctly your transmission will not shift like it should and will cause premature band wear.

<< Thank you very much for answering my question about adjusting the bands. I'm still in doubt about something. Does band adjustment involve only tightening a bunch of bolts? I can get the torque wrenches, but when I drop the transmission pan, am I going to be puzzled by some new hi-tech scheme. >>
Here is the procedure:
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 front (kickdown) band adjusting screw locknut.
(3) Back locknut off 3-5 turns. Be sure adjusting screw turns freely in case. Apply lubricant to screw threads if necessary.
(4) Use a 0-100 in. lb. torque wrench to set the adjusting screw. A 5/16 or 11/32 in. 12 point socket, or crowfoot wrench will be required to turn the adjusting screw.
(5) Tighten the band adjusting screw to 72 in. lbs. torque. Then back off adjusting screw as follows: 2 1/4 turns on 42RH (3.9L engine in 4 X 2 1500) 2 7/8 turns on 46RH (3.9L, 5.2L, 5.9L engines) 1 7/8 turns on 47RH (V-10 and Cummins diesel engines)
(6) Hold adjuster screw in position and tighten locknut to 30 ft. lbs torque.
REAR BAND ADJUSTMENT
The rear (Low - Reverse) band adjusting screw is located inside the transmission on the rear band lever.
(1) Remove Transmission oil pan and drain fluid.
(2) Loosen band adjusting screw locknut 5-6 turns. Be sure screw turns freely in lever.
(3) Use a 0 - 100 in. lb. torque wrench to tighten the adjusting screw.
(4) Tighten adjusting screw to 72 in. lbs. torque. Then back off band adjusting screw as follows: 4 turns on 42RH 2 turns on 46RH 3 turns on 47RH
(5) Hold adjusting screw in place and tighten locknut to 25 ft. lbs. torque.
(6) Position new gasket on oil pan and install pan on transmission. Tighten pan bolts to 13 ft. lbs. torque.
(7) Lower vehicle and refill transmission with Mopar ATF Plus, Type 7176 fluid.
This procedure is copied from the 1995 Ram Truck Service Manual from Chrysler. I don't know if there is any change to the procedure for the later models, but I suspect it is the same. I will post this to the RTML as some others may find it useful.
