This is a demonstration of how I tightened the bands of my automatic transmission and changed the transmission fluid and filter. The vehicle is a 1998 Dodge Ram 1500 4X4 with a 46RE transmission. This repair was done after a transfer case repair which required removal of the propeller shafts. With the front shaft out of the way, access to the front band adjustment screw was better than normal. It is possible to do this with the shaft in place, but access for demonstration is not as good. For details of how the propeller shaft is removed, see my other videos on repairing a Dodge transfer case oil leak.
Note that the details of how this is done, especially the torque settings and the number of rotations backward after ideal torque, are very specific to the 46RE transmission. Be sure the locknut is backed off enough that it doesn't bottom out when the adjustment screw is tightened. Before ever doing this type of procedure yourself, you should consult the dealers repair manual and verify the specific procedure in your car.
