How to adjust bands and change automatic transmission fluid
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.
This is an amateur demonstration done for entertainment purposes only. The
information offered here is given in good faith but with no guarantees of
accuracy or safety. Any misadventure you encounter if you decide to do
maintenance on your own vehicle is your responsibility.
